Abstract

This document describes how to prepare internationalized host names for
for use in the DNS. The steps include:
- mapping characters to other characters, such as to change their case
- normalizing the characters
- excluding characters that are prohibited from appearing in
internationalized host names

1. Introduction

When expanding today's DNS to include internationalized host names,
those new names will be handled in many parts of the DNS. The IDN
Working Group's requirements document [IDNReq] describes a framework for
domain name handling as well as requirements for the new names. The IDN
Working Group's comparison document [IDNComp] gives a framework for how
various parts of the IDN solution work together.

A user can enter a domain name into an application program in a myriad
of fashions. Depending on the input method, the characters entered in
the domain name may or may not be those that are allowed in
internationalized host names. Thus, there must be a way to normalized
the user's input before the name is resolved in the DNS.

It is a design goal of this document to allow users to enter host names
in applications and have the highest chance of getting the name correct.
This means that the user should not be limited to only entering exactly
the characters that might have been used, but to instead be able to
enter characters that unambiguously normalize to characters in the
desired host name. At the same time, this process must not introduce any
chance that two host names could be represented by two distinct strings
of characters that look identical to typical users. It is also a design
goal to have all preprocessing of IDN done before going on the wire, so
that no transformation is done in the DNS server space. Name preparation
can be done in other places, such as in the registration process.

This document describes the steps needed to convert a name part from one
that is entered by the user to one that can be used in the DNS.

1.1 Terminology

The key words "MUST", "SHALL", "REQUIRED", "SHOULD", "RECOMMENDED", and
"MAY" in this document are to be interpreted as described in RFC 2119
[RFC2119].

Examples in this document use the notation for code points and names
from the Unicode Standard [Unicode3] and ISO 10646. For example, the
letter "a" may be represented as either "U+0061" or "LATIN SMALL LETTER
A". In the lists of prohibited characters, the "U+" is left off to make
the lists easier to read.

Note: A glossary of terms used in Unicode and ISO 10646 can be found in
[Glossary]. Information on the 10646/Unicode character model can be
found in [CharModel].


2. Preparation Overview

The steps for preparing names are:

1) Input from the application service interface -- This can be done in
many ways and is not specified in this document

2) Map -- For each character in the input, check if it has a mapping
and, if so, replace it with its mapping. The mappings are a combination
of folding uppercase characters to lowercase and hyphen mapping. This
is described in Section 4.

3) Normalize -- Normalize the characters. This is described in Section 5.

4) Look for prohibited output -- Check for any characters that are not
allowed in the output. If any are found, return an error to the
application service interface. This is described in Section 6.

5) Resolution of the prepared name -- This must be specified in a
different IDN document.

The above steps MUST be performed in the order given in order to comply
with this specification.

The steps in this document have associated tables in the document. The
tables are derived from outside sources, and the derivation is briefly
described in the document. Although a great deal of effort has gone into
preparing the tables, there is a chance that the tables do not correctly
reflect the outside sources. Regardless of whether or not the tables
differ from the sources, implementations MUST use the tables in this
document for their processing. That is, if there is an error in the
tables, the tables must still be used. Future versions of this document
may include corrections and additions to the tables.


3. Mapping

Each character in the input stream is checked against the mapping table.
The mapping table can be found in Appendix E of this document. That
table includes all the steps described in the subsections below.

The mappings can be one-to-none, one-to-one, or one-to-many. That is,
some characters may be eliminated or replaced by more than one
character, and the output of this step might be shorter or longer than
the input.

Design note: Characters that are not wanted in internationalized name
parts can either be mapped to nothing in the mapping step, or cause an
error in the prohibition step. The general guideline used to pick
between the two outcomes was that removing alphabetic, non-protocol
characters be done in the mapping step, but all other removals be done
in the prohibition step. This allows for simple linguistic errors on the
part of an input mechanism to be caught in the mapping step, but to not
hide serious errors such as entering protocol characters or invisible
characters from the user.

3.1 Case mapping

For each character in the input, if there is a lowercase mapping for
that character, the input character is changed to the mapped lowercase
character(s). The entries in the mapping table are derived from [UTR21].

Design note: this step could have been "change all lowercase characters
into uppercase characters". However, the upper-to-lower folding was
chosen because most users of the Internet today enter host names in
lowercase.

3.2 Additional folding mappings

There are some characters that do not have mappings in [UTR21] but still
need processing. These characters include a few Greek characters and
many symbols that contain Latin characters. The list of characters to
add to the mapping table were determined by the following algorithm:

b = Normalize(Fold(a));
c = Normalize(Fold(b));
if c is not the same as b, add a mapping for "a to c".

Because Normalize(CaseFold(c)) always equals c, the table is stable from
that point on.

3.3 Mapped out

The following characters are simply deleted from the input (that is,
they are mapped to nothing) because their presence or absence should not
make two domain names different.

Some characters are only useful in line-based text, and are otherwise
invisible and ignored.

00AD        SOFT HYPHEN
1806        MONGOLIAN TODO SOFT HYPHEN
200B        ZERO WIDTH SPACE
FEFF        ZERO WIDTH NO-BREAK SPACE

Variation selectors and cursive connectors select different glyphs, but
do not bear semantics.

180B        MONGOLIAN FREE VARIATION SELECTOR ONE
180C        MONGOLIAN FREE VARIATION SELECTOR TWO
180D        MONGOLIAN FREE VARIATION SELECTOR THREE
200C        ZERO WIDTH NON-JOINER
200D        ZERO WIDTH JOINER


4. Normalizaiton

The output of the mapping step is normalized using form KC, as described
in [UTR15]. Using form KC instead of form C causes many characters that
are identical or near-identical to be converted into a single character.
Note that this specification refers to a specific vesion of [UTR15].
If a later version of [UTR15] changes the algorithm used for normalizing,
that later version MUST NOT be used with this specification. Note that
it is likely that this specification will be revised if UTR15 is changed,
but until that happens, only the specified version of [UTR15] must
be used.


5. Prohibited Output

Before the text can be emitted, it must be checked for prohibited
characters. There is a variety of prohibited characters, as described in
this section.

One of the goals of IDN is to allow the widest possible set of host
names as long as those host names do not cause other problems, such as
conflict with other standards. Specifically, experience with current DNS
names have shown that there is a desire for host names that include
personal names, company names, and spoken phrases. A goal of this
section is to prohibit as few characters that might be used in these
contexts as possible.

Note that every character listed in this section MUST NOT be transmitted
on the DNS service interface. If a DNS server receives a request
containing a prohibited character, then the DNS server MUST NOT
resolve that name.

Some characters listed in one section would also appear in other
sections. Each character is only listed once.

The collected list of prohibited characters can be found in Appendix F
of this document. The list in Appendix F MUST be used by implementations
of this specification. If there are any discrepancies between the list
in Appendix F and subsections below, the list Appendix F always takes
precedence.

5.1 Currently-prohibited ASCII characters

Some of the ASCII characters that are currently prohibited in host names
by [STD13] are also used in protocol elements such as URIs. The other
characters in the range U+0000 to U+007F that are not currently allowed
are also prohibited in host name parts to reserve them for future use in
protocol elements.

0000-002C
002E-002F
003A-0040
005B-0060
007B-007F

5.2 Space characters

Space characters would make visual transcription of URLs nearly
impossible and could lead to user entry errors in many ways.

0020        SPACE
00A0        NO-BREAK SPACE
2000        EN QUAD
2001        EM QUAD
2002        EN SPACE
2003        EM SPACE
2004        THREE-PER-EM SPACE
2005        FOUR-PER-EM SPACE
2006        SIX-PER-EM SPACE
2007        FIGURE SPACE
2008        PUNCTUATION SPACE
2009        THIN SPACE
200A        HAIR SPACE
202F        NARROW NO-BREAK SPACE
3000        IDEOGRAPHIC SPACE
1680        OGHAM SPACE MARK
200B        ZERO WIDTH SPACE

5.3 Control characters

Control characters cannot be seen and can cause unpredictable results
when displayed.

0000-001F   [CONTROL CHARACTERS]
007F        DELETE
0080-009F   [CONTROL CHARACTERS]
2028        LINE SEPARATOR
2029        PARAGRAPH SEPARATORS

5.4 Private use and replacement characters

Because private-use characters do not have defined meanings, they are
prohibited. The private-use characters are:

E000-F8FF   [PRIVATE USE, PLANE 0]
F0000-FFFFD [PRIVATE USE, PLANE 15]
100000-10FFFD  [PRIVATE USE, PLANE 16]

The replacement character (U+FFFD) has no known semantic definition in a
name, and is often used in renderers to say "there would be some
character here, but it cannot be rendered". For example, on a computer
with no Asian fonts, a name with three katakana characters might be
rendered with three replacement characters.

FFFD        REPLACEMENT CHARACTER

5.5 Non-character codepoints

Non-character code points are code points that have been assigned in
ISO 10646 but are not characters. Because they are already assigned,
they are guaranteed not to later change into characters.

FFFE-FFFF   [NONCHARACTER CODE POINTS]
1FFFE-1FFFF [NONCHARACTER CODE POINTS]
2FFFE-2FFFF [NONCHARACTER CODE POINTS]
3FFFE-3FFFF [NONCHARACTER CODE POINTS]
4FFFE-4FFFF [NONCHARACTER CODE POINTS]
5FFFE-5FFFF [NONCHARACTER CODE POINTS]
6FFFE-6FFFF [NONCHARACTER CODE POINTS]
7FFFE-7FFFF [NONCHARACTER CODE POINTS]
8FFFE-8FFFF [NONCHARACTER CODE POINTS]
9FFFE-9FFFF [NONCHARACTER CODE POINTS]
AFFFE-AFFFF [NONCHARACTER CODE POINTS]
BFFFE-BFFFF [NONCHARACTER CODE POINTS]
CFFFE-CFFFF [NONCHARACTER CODE POINTS]
DFFFE-DFFFF [NONCHARACTER CODE POINTS]
EFFFE-EFFFF [NONCHARACTER CODE POINTS]
FFFFE-FFFFF [NONCHARACTER CODE POINTS]
10FFFE-10FFFF  [NONCHARACTER CODE POINTS]

5.6 Surrogate codes

The following are permanently reserved for use as surrogate code values
in the UTF-16 encoding, will never be assigned to characters and are
therefore prohibited:

D800-DFFF   [SURROGATE CODES]

5.7 Inappropriate for plain text

The following characters should not appear in regular text.

FFF9        INTERLINEAR ANNOTATION ANCHOR
FFFA        INTERLINEAR ANNOTATION SEPARATOR
FFFB        INTERLINEAR ANNOTATION TERMINATOR
FFFC        OBJECT REPLACEMENT CHARACTER

5.8 Inappropriate for domain names

The ideographic description characters allow different sequences of
characters to be rendered the same way, which makes them inappropriate
for host names that must have a single canonical order.

2FF0-2FFF   IDEOGRAPHIC DESCRIPTION CHARACTERS

5.9 Change display properties

The following characters, some of which are deprecated in ISO 10646,
can cause changes in display or the order in which characters appear
when rendered.

200E        LEFT-TO-RIGHT MARK
200F        RIGHT-TO-LEFT MARK
202A        LEFT-TO-RIGHT EMBEDDING
202B        RIGHT-TO-LEFT EMBEDDING
202C        POP DIRECTIONAL FORMATTING
202D        LEFT-TO-RIGHT OVERRIDE
202E        RIGHT-TO-LEFT OVERRIDE
206A        INHIBIT SYMMETRIC SWAPPING
206B        ACTIVATE SYMMETRIC SWAPPING
206C        INHIBIT ARABIC FORM SHAPING
206D        ACTIVATE ARABIC FORM SHAPING
206E        NATIONAL DIGIT SHAPES
206F        NOMINAL DIGIT SHAPES


6. Unassigned Characters

All characters not yet assigned in [ISO10646] are called "unassigned
characters". Authoritative name servers MUST NOT have internationalized
name parts that contain any unassigned characters. DNS requests MAY
contain name parts that contain unassigned characters. Note that this is
the only part of this document where the requirements for queries
differs from the requirements for names in DNS zones.

Using two different policies for where unassigned characters can appear
in the DNS prevents the need for versioning the IDNprotocol [IDNrev].
This is very useful since it makes the overall processing simpler and do
not impose a "protocol" to handle versioning. It is expected that ISO
10646 will be updated fairly frequently; recently, it has happened
approximately once a year. Each time a new version of ISO 10646 appears,
a new version of this document can be created. Some end users will want
to use the new characters as soon as they are defined.

The list of unassigned characters can be found in Appendix G of this
document. The list in Appendix G MUST be used by implementations of this
specification. If there are any discrepancies between the list in
Appendix G and the ISO 10646 specification, the list Appendix G always
takes precedence.

Due to the way that versioning is handled in this section, host names
that are embedded in structures that cannot be changed (such as the
signed parts of digital certificates) MUST NOT have internationalized
name parts that contain any unassigned characters.

6.1 Categories of characters

Each character in ISO 10646 can be categorized by how it acts in
the process described in earlier sections of this document:

AO      Characters that may be in the output

MN      Characters that cannot be in the output because they are
          mapped to nothing or never appear as output from
          normalization

D       Characters that cannot be in the output because they are
          disallowed in the prohibition step

U       Unassigned characters

A subsequent version of this document that references a newer version of
ISO 10646 with new characters will inherently have some characters move
from category U to either D, MN, or AO. For backwards compatibility, no
future version of this document will move characters from any other
category. That is, no current AO, MN, or D characters will ever change
to a different category.

Authoritative name servers MUST NOT contain any name that has characters
outside of AO for the latest version of this document. That is, they are
forbidden to contain any IDN names containing characters from the MN, D,
or U categories.

Applications creating name queries MUST treat U code points as if they
were AO when preparing the name parts according to this document. Those
applications MAY optionally have a preprocess that provide stricter
checks: treating unassigned characters in the input as errors, or
warning the user about the fact that the character is unassigned in the
version of this document that the software is based on; such a choice is
a local matter for the software.

Non-authoritative DNS servers MAY reject names that contain characters
that are in categories MN or D for the version of this document that
they implement, but MUST NOT reject names because they contain name
parts with characters from category U.

6.2 Reasons for difference between authoritative servers and requests

Different software using different versions of this document need to
interoperate with maximal compatibility. The scheme described in this
section (authoritative name servers MUST NOT use unassigned characters,
requests MAY include unassigned characters) allows that compatibility
without introducing any known security or interoperability issues.

The list below shows what happens if a request contains a character from
category U that is allowed in a newer version of this document. The
request either resolves to the domain name that was intended, or
resolves to no domain at all. In this list, the request comes from an
application using version "oldVersion" of this document, the
authoritative name server is using version "newVersion" of this
document, and the character X was in category U on oldVersion, and has
changed category to AO, MN, or D. There are 3 possible scenarios:

1. X becomes AO -- In newVersion, X is in category AO. Because the
application passed X through, it gets back correct data from the
authoritative name server. There is one exceptional case, where X is a
combining mark.

The order of combining marks is normalized, so if another combining mark
Y has a lower combining class than X then XY will be put in the
canonical order YX. (Unassigned characters are never reordered, so this
doesn't happen in oldVersion). If the request contains YX, the request
will get correct data from the authoritative name server. However, no
domain name can be registered with XY, so a request with XY will get a
"no such host" error.

2. X becomes MN -- In newVersion, X is normalized to character "nX" and
therefore X is now put in category MN. This cannot exist in any domain
name, so any request containing X will get back a "no such host" error.
Note, however, if the request had contained the letter nX, it would have
gotten back correct data.

3. X becomes D -- In newVersion, X is in category MN. This cannot exist
in any domain name, so any request containing X will get back a "no such
host" error.

In none of the cases does the request get data for a host name other
than the one it actually wanted.

The processing in this document is always stable. If a string S is the
result of processing on newVersion, then it will remain the same when
processed on oldVersion.

There is always a way for the application to get the correct data from
the authoritative name server. For example, suppose that <ALPHA> was
unassigned in oldVersion, and that it is assigned in newVersion, but
case-folded to <alpha>. As long as the application supplies strings
containing <alpha> instead of <ALPHA>, the correct data will be
returned. Because the processing is stable, a different application
running newVersion can pass a processed host name to the application
running oldVersion. It will only contain <alpha>, and will return the
correct results from the authoritative name server.

6.3 Versions of applications and authoritative name servers

Another way to see that this versioning system works is to compare what
happens when an application uses a newer or older version of this
document.

Newer application -- Suppose that a application or intermediary DNS
server is using version newVersion and the authoritative name server is
using version oldVersion. This case is simple: there will be no names on
the server that cannot be accessed by the application because the
resolver uses a superset of the code points accepted by the server.

Newer server -- Suppose that an application or intermediary DNS server
is using oldVersion and the authoritative name server is using
newVersion. Because the application passed through any unassigned
characters, the user can access names on the server that use characters
in newVersion. No names on the site can have characters that are
unassigned in newVersion, since that is illegal. In this case, the
application has to enter the unassigned characters in the correct order,
and has to use unassigned characters that would make it through both the
mapping and the normalization steps.


7. Security Considerations

Much of the security of the Internet relies on the DNS. Thus, any change
to the characteristics of the DNS can change the security of much of the
Internet.

Host names are used by users to connect to Internet servers. The
security of the Internet would be compromised if a user entering a
single internationalized name could be connected to different servers
based on different interpretations of the internationalized host name.

Current applications may assume that the characters allowed in host
names will always be the same as they are in [STD13]. This document
vastly increases the number of characters available in host names. Every
program that uses "special" characters in conjunction with host names
may be vulnerable to attack based on the new characters allowed by this
specification.

E. Mapping Table

The following is the mapping table from Section 3. The table has three
columns:
- the character that is mapped from
- the zero or more characters that it is mapped to
- the reason for the mapping
The columns are separated by semicolons. Note that the second column may
be empty, or it may have one character, or it may have more than one
character, with each character separated by a space.
