Internet-Draft iris-areg October 2004
1. Introduction
This document describes an IRIS namespace for Internet address
registries using an XML Schema [5] derived from and using the IRIS
[9] schema. This schema and registry type are provided to
demonstrate the extensibility of the IRIS framework beyond the use of
domains, a criteria defined in CRISP [11].
The schema given is this document is specified using the Extensible
Markup Language (XML) 1.0 as described in XML [2], XML Schema
notation as described in XML_SD [4] and XML_SS [5], and XML
Namespaces as described in XML_NS [3].
Examples of client/server XML exchanges with this registry type are
available in Appendix A.

2. Document Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC2119 [8].

3. Schema Description
IRIS requires the derivation of both query and result elements by a
registry schema. These descriptions follow.
The descriptions contained within this section refer to XML elements
and attributes and their relation to the exchange of data within the
protocol. These descriptions also contain specifications outside the
scope of the formal XML syntax. Therefore, this section will use
terms defined by RFC 2119 [8] to describe the specification outside
the scope of the formal XML syntax. While reading this section,
please reference Section 5 for needed details on the formal XML
syntax.
3.1 Query Derivatives
3.1.1 <findContacts> Query
<findContacts> searches for contacts given search constraints.
The allowable search fields are handled by one of the elements in the
"contactSearchGroup" (see Section 3.1.8).
This query also provides optional <language> elements containing
language tags. Clients MAY use these elements to give a hint about
the natural language(s) of the affected element. Servers MAY use
this information in processing the query, such as tailoring
normalization routines to aid in more effective searches.
The client SHOULD pass the names unchanged to the server, and the
implementation of the server decides if the search is case sensitive
or not.
3.1.2 <findOrganizations>
The <findOrganizations> element allows searches by name of
organizations.
The child element <name> allows the query to be constrained based on
the name of the organization. The constraint can either constrain
the query by an exact match using the <exactMatch> element, or it may
constrain the query by a subset of the name using the <beginsWith>
and <endsWith> elements.
This query also provides optional <language> elements containing
language tags. Clients MAY use these elements to give a hint about
the natural language(s) of the affected element. Servers MAY use
this information in processing the query, such as tailoring
Gunduz & Newton Expires April 4, 2005 [Page 5]
Internet-Draft iris-areg October 2004
normalization routines to aid in more effective searches.
The client SHOULD pass the names unchanged to the server, and the
implementation of the server decides if the search is case sensitive
or not.
3.1.3 <findAutonomousSystemsByName> and <findNetworksByName>
The <findAutonomousSystemsByName> and <findNetworksByName> elements
allow searches by name of autonomous systems, and networks,
respectively. Both have the same format.
The child element <name> may either have as children the <exactMatch>
element or the <beginsWith> and <endsWith> elements.
3.1.4 <findNetworksByAddress>
The <findNetworkByAddress> element is a query for a network given a
related IP address or IP address range. It has the following child
elements:
o <ipv4Address> - has a child <start> element containing the
starting IPv4 address of the network and an optional child of
<end> containing the ending IPv4 address of the network.
o <ipv6Address> - same as <ipv4Address> but the child addresses
contain IPv6 addresses. Clients MUST convert any short-form
notation to the fully-qualified notation.
o <specificity> - determines the network specificity for the search
(see Section 4). Valid values are "exact-match",
"all-less-specifics", "one-level-less-specifics",
"all-more-specifics", and "one-level-more-specifics". This
element may have the optional attribute 'allowEquivalences'. When
set to "true", the result set should include networks with
equivalent starting and ending addresses.
The results from this query MUST be either the <ipv4Network> result
or the <ipv6Network> result. More than one network result MAY be
returned.
3.1.5 <findNetworkBySpecificity>
The <findNetworkBySpecificity> element is a query for a network given
a the handle of a related network. It has the following child
elements:
o <networkHandle> - Specifies the network handle.
o <specificity> - determines the network specificity for the search
(see Section 4). Valid values are "all-less-specifics",
"one-level-less-specifics", "all-more-specifics", and
"one-level-more-specifics".
Gunduz & Newton Expires April 4, 2005 [Page 6]
Internet-Draft iris-areg October 2004
The results from this query MUST be either the <ipv4Network> result
or the <ipv6Network> result. More than one network result MAY be
returned.
This query could be used to discover the parentage relationships
between networks that have the same starting and ending addresses.
3.1.6 <findASNByNumber>
The <findASNByNumber> element allows a search for autonomous system
number ranges given a related ASN range. It has the following child
elements:
o <asNumberStart> - Specifies the start of the ASN range.
o <asNumberEnd> - Specifies the end of the ASN range.
o <specificity> - determines the range specificity for the search
(see Section 4). Valid values are "exact-match",
"all-less-specifics", "one-level-less-specifics",
"all-more-specifics" and "one-level-more-specifics". This element
may have the optional attribute 'allowEquivalences'. When set to
"true", the result set should include ranges with equivalent
starting and ending numbers.
The results from this query MUST be <autonomousSystem> result. More
than one result MAY be returned.
3.1.7 <findByContact>
The <findByContact> element allows a search for autonomous system
number ranges, IP networks and organizations on fields associated
with that entity's contact. Search constraints of <returnASNs>,
<returnIPv4Networks>, <returnIPv6Networks> and <returnOrganizations>
MUST restrict the results to ASN ranges, IPv4 networks, IPv6 networks
and organizations, respectively.
The allowable search fields are handled with either the
<contactHandle> element or one of the elements in the
"contactSearchGroup" (see Section 3.1.8). The <contactHandle>
element allows for the entities to be selected based on the contact
having the specified contact handle.
The query MAY also be constrained further using the optional <role>
element. The contents of this element signify the role the contact
has with the entity.
This query also provides optional <language> elements containing
language tags. Clients MAY use these elements to give a hint about
the natural language(s) of the affected element. Servers MAY use
this information in processing the query, such as tailoring
Gunduz & Newton Expires April 4, 2005 [Page 7]
Internet-Draft iris-areg October 2004
normalization routines to aid in more effective searches.
The results from this query MUST be the <ipv4Network> results, the
<ipv6Network> results, the <autonomousSystem> or <organization>
results. More than one result MAY be returned and the results MAY be
of mixed types.
3.1.8 Contact Search Group
Some of the queries above have similar query constraints for
searching on contacts. This section describes those common
parameters.
<commonName> allows the query to be constrained based on the common
name of the contact. The constraint can either constrain the query
by an exact match using the <exactMatch> element, or it may constrain
the query by a subset of the common name using the <beginsWith> and
<endsWith> elements.
<organization> allows the query to be constrained based on the
organization ID (handle) of the contact.
<eMail> constrains the query based on the e-mail address of the
contact. This may be done by an exact e-mail address using the
<exactMatch> element or by any e-mail address in a domain using the
<inDomain> element. The <inDomain> MUST only contain a valid domain
name (i.e. no '@' symbol), and the matching SHOULD take place only
on the domain given (i.e. no partial matches with respect to
substrings or parent domains).
The <city>, <region>, and <postalCode> elements restrict the scope of
the query based on the city, region, or postal code of the contact,
respectively. Each one must only contain an <exactMatch> element
containing the exact city, region, or postal code (i.e. no substring
searches).
3.2 Result Derivatives
3.2.1 <ipv4Network> and <ipv6Network> Results
The <ipv4Network> and <ipv6Network> share a common defintion of
'ipNetworkType'. It has the following child elements:
o <networkHandle> contains the registry-unique assigned handle for
this network.
o <name> contains a human friendly name for the network.
o <startAddress> contains the first IP address of the network.

described by this element.
o <eMail> contains the email address for this contact.
o <sip> contains the sip address for this contact.
o <organization> contains an entity reference to the organization
associated with this contact. The referent MUST be an

3.2.5 Contact References
The registry schema defined in Section 5 normalizes out a group of
elements used to reference contacts. This group is used by many of
the result types for this registry. The group has the following
elements, each of which may appear as many times as needed. The
referent of each MUST be <contact> (Section 3.2.3) results.
o <adminContact>
o <techContact>

Gunduz & Newton Expires April 4, 2005 [Page 10]
Internet-Draft iris-areg October 2004
3.2.6 Common Result Child Elements
The registry schema defined in Section 5 normalizes out a group of
common elements used most of the reult types. The group has the
following elements:
o <numberResourceRegistry> contains an entity reference to the
number resource registry of record. The referent MUST be an
<organization> (Section 3.2.4) result.

an entity that is indirectly associated with this result object.
This element can be used for comments and remarks.
3.3 Support for <iris:lookupEntity>
The following types of entity classes are recognized by the
<lookupEntity> query of IRIS for this registry:
o ipv4-handle - a registry unique identifier specifying an IPv4
network. Queries with these names will yield a <ipv4Network>
result.
o ipv6-handle - a registry unique identifier specifying an IPv6
network. Queries with these names will yield a <ipv6Network>
result.
o as-handle - a registry unique identifier specifying an autonomous
system. It yields a result of <autonomousSystem>.
o contact-handle - a registry unique identifier of a contact.
Yields a result of <contact>.
o organization-id - a registry unique identifier of an organization.
Yields a result of <organization>.
o The entity names of these entity classes are case insensitive.

4. Terminology for Nesting of Networks
The following terms are defined for describing the nesting of IP
networks.
o More specific: Given two networks, A and B, A is more specific
than B if network B includes all space of network A, and if
network B is larger than network A.
o Less specific: Opposite of more specific. The network B is less
specific than network A if network A's all space is included in
network B and if network A is smaller than network B.
o Most specific: Given a set of networks, the network or networks
that are more specific than zero or more of other networks in the
set, and that are not a less specific of any of the networks in
the set.
o Least specific: Given a set of networks, the network or networks
that are not more specific to any of the other networks in the
set.
Examples:
+-------------------------------------------------------+
| |
| Given the networks A, B, C and D as follows: |
| |
| A |---------------------------------| |
| B |-----------------| |
| C |---------| |
| D |-------| |
| |
| |
| The network A is less specific than B, C and D. |
| The network B is more specific than A. |
| Among these four networks, A is the least specific, |
| and C and D are the most specific networks. |
| |
+-------------------------------------------------------+
Figure 1: Nesting Example 1
Gunduz & Newton Expires April 4, 2005 [Page 12]
Internet-Draft iris-areg October 2004
+-------------------------------------------------------+
| |
| Given the networks E, F and G: |
| |
| E |----------| |
| F |--------------| |
| G |---| |
| |
| The networks E and F are least specific networks. |
| The networks F and G are most specific networks. |
| |
+-------------------------------------------------------+
Figure 2: Nesting Example 2
The following definitions assume that there are no overlapping
networks in the database. A network overlaps with another one when
they encompass each other's space partially. Examples:
A |---------------------|
B |----------------------------|
Figure 3: Nesting Example 3
C |------------------|
D |---------|
Figure 4: Nesting Example 4
Here, the networks C and D are NOT overlapping networks, because even
if network D encompasses a part of network C's space, network C does
not encompass network D's space partially (it encompasses network D
completely).
The address directory can contain more than one network with the same
range. They are said to be exact match networks.
Parent/child relationship in the internet address directory is
unidirectional. That is, there might also be parent/child
relationship with exact match networks, but a network cannot be a
parent and a child of its exact match network at the same time.
Nested matching searches:
[1] Given a range, find all the networks that contain that range (ie,
all less specifics and exact matches). These networks are the
networks that fulfill the following condition:
Gunduz & Newton Expires April 4, 2005 [Page 13]
Internet-Draft iris-areg October 2004
(start(network) <= start(search)) AND (end(network) >= end(search))
[2] Given a range, find only the most specific network that contains
that range (could be multiple networks, but usually single); This is
the set of networks from [1], with the provision that: no network in
the return set is contained by any other network in the set. If
there are exact match networks in the set from [1], they both must
appear in the result set. The result set must not contain a network
that is exact match to the query range.
A |-------------------------------|
B |---------------------------|
C |-------|
Query |- - - - - - - - - -|
Figure 5: Nesting Example 5
In the above case, the query must return B.
A |-------------------------------|
B |---------------------------|
C |---------------------------|
D |-------|
Query |- - - - - - - - - -|
Figure 6: Nesting Example 6
Here, the query must return B and C (they are exact matches of each
other).
A |-------------------------------|
B |---------------------------|
C |---------------------------|
D |-------|
Query |- - - -|
Figure 7: Nesting Example 7
Here, the query must return B and C (they are exact matches of each
other). D must not be in the result set, as it is exact match to the
query.
[3] Given a range, find all the networks that are fully within that
range. The set must not contain an exact match:
(start(network) >= start(search)) AND (end(network) <= end(search))
Gunduz & Newton Expires April 4, 2005 [Page 14]
Internet-Draft iris-areg October 2004
AND NOT ((start(network) = start(search)) AND (end(network) =
end(search)))
[4] Given a range, find only the least specific networks that are
fully within that range. This is the set of networks from [3], with
the provision that:
no network in the return set contains any other network in the return
set.
Query |- - - - - - - - - - - - - - - - - - - - - - -|
A |------------------|
B |-------------------------|
C |--------|
D |---------|
Figure 8: Nesting Example 8
[5] Given a range, find the networks that begin and end on the same
IP addresses as the range ("exact match").
That is, the networks that fulfill the following condition:
(start(network) = start(search)) AND (end(network) = end(search))
[6] Given a range find the exact match network if exists, and if not,
perform the [2] search.
For the cases [1]-[6], if a network handle is given as the input,
then the server must find the network with this handle, and then
perform the specified search for its range.
Parent-child relationship searches:
[7] Given a network handle, find the network that is the direct (one
level up) parent of the network with the given handle.
[8] Given a network handle, find the network or networks that are
direct (one level down) children of the network with the handle
given.

6. BEEP Transport Compliance
IRIS allows several extensions of the core capabilities. This
section outlines those extensions allowable by IRIS-BEEP [10].
6.1 Message Pattern
This registry type uses the default message pattern as described in
IRIS-BEEP [10].
6.2 Server Authentication
This registry type uses the default server authentication method as
described in IRIS-BEEP [10].
Gunduz & Newton Expires April 4, 2005 [Page 33]
Internet-Draft iris-areg October 2004
7. URI Resolution
7.1 Application Service Label
The application service label associated with this registry type MUST
be "AREG1". This is the abbreviated form the URN for this registry
type, urn:ietf:params:xml:ns:areg1.
7.2 Top-Down Resolution
The top-down alternative resolution method MUST be identified as
'top' in IRIS URI's.
The client SHOULD start every query from the CRISP server
crisp.nro.org and follow the referrals to find the authoritative
server to actually query.

8. Internationalization Considerations
This document lays out no new considerations for internationalization
beyond that specified in IRIS [9].

9. IANA Considerations
The following URN will need to be registered with IANA according to
the IANA considerations defined in IRIS [9]:
urn:ietf:params:xml:ns:areg1
The following NAPSTR application service label will need to be
registered with IANA according to the IANA considerations defined in
IRIS [9]:
AREG1

Appendix B. Acknowledgements
Many of the concepts concerning the use of SRV records for step-wise
refinement towards finding authoritative servers and many of the
details of result objects in this draft were originally created by
Eric A. Hall in his memos regarding the use of LDAP to satisfy the
CRISP requirements. These concepts have contributed significantly to
the development of this protocol.
