Abstract
The Registration Data Access Protocol (RDAP) is used by Regional
Internet Registries (RIRs) and Domain Name Registries (DNRs) to
provide access to their resource registration information. The core
specifications for RDAP define basic search functionality, but there
are various IP and ASN-related search options provided by RIRs via
their Whois services for which there is no corresponding RDAP
functionality. This document extends RDAP to support those search
options.

1. Introduction
The Registration Data Access Protocol (RDAP) [RFC7480] is used by
Regional Internet Registries (RIRs) and Domain Name Registries (DNRs)
to provide access to their resource registration information. The
core specifications for RDAP define basic search functionality, but
this is limited to domains, nameservers, and entities. No searches
were defined for IP networks or autonomous system numbers.
In an effort to have RDAP reach feature parity with the existing RIR
Whois services in this respect, this document defines additional
search options for IP networks and autonomous system numbers, along
with an additional link relation for finding more-specific resources.
1.1. Requirements Language
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] [RFC8174].
2. Search Path Segment Specification
The new resource type path segments for search are:
Harrison & Singh Expires 9 April 2023 [Page 2]
Internet-Draft RDAP RIR Search October 2022
'ips': Used to identify an IP network search using a pattern to
match one of a set of IP network attributes.
'autnums': Used to identify an Autonomous System number search
using a pattern to match one of a set of Autonomous System number
attributes.
Search path segments are formed using the same logic as in section
3.2 of [RFC9082].
2.1. IP Network Search
Syntax: ips?handle=<handle search pattern>
Syntax: ips?name=<name search pattern>
Searches for IP network information by handle are specified using the
form:
ips?handle=XXXX
XXXX is a search pattern representing an IP network identifier, the
syntax for which is specific to the registration provider. The
following URL would be used to find information for IP networks with
handles matching the "NET-199*" pattern:
https://example.com/rdap/ips?handle=NET-199*
Searches for IP network information by name are specified using the
form:
ips?name=XXXX
XXXX is a search pattern representing an IP network identifier that
is assigned to the network registration by the registration holder.
The following URL would be used to find information for IP networks
with names matching the "NET-EXAMPLE-*" pattern:
https://example.com/rdap/ips?name=NET-EXAMPLE-*
2.2. Autonomous System Number Search
Syntax: autnums?handle=<handle search pattern>
Syntax: autnums?name=<name search pattern>
Searches for autonomous system number information by handle are
specified using the form:
Harrison & Singh Expires 9 April 2023 [Page 3]
Internet-Draft RDAP RIR Search October 2022
autnums?handle=XXXX
XXXX is a search pattern representing an autonomous system number
identifier, the syntax for which is specific to the registration
provider. The following URL would be used to find information for
autonomous system numbers with handles matching the "AS1*" pattern:
https://example.com/rdap/autnums?handle=AS1*
Searches for autonomous system number information by name are
specified using the form:
autnums?name=XXXX
XXXX is a search pattern representing an autonomous system number
identifier that is assigned to the autonomous system number
registration by the registration holder. The following URL would be
used to find information for autonomous system numbers with names
matching the "ASN-EXAMPLE-*" pattern:
https://example.com/rdap/autnums?name=ASN-EXAMPLE-*
3. Responding To Searches
As with [RFC9083], responses to the IP network and autonomous system
number searches defined in the previous section take the form of an
array of object instances, where each instance is an appropriate
object class for the search (i.e., a search for /ips yields an array
of IP network object instances, and a search for /autnums yields an
array of autonomous system number object instances). These arrays
are contained within the response object.
The names of the arrays are as follows:
for /ips searches, the array is "ipSearchResults"; and
for /autnums searches, the array is "autnumSearchResults".
4. Link Relations
An IP network, autonomous system number, or reverse domain object may
have a 'parent' object and one or more 'child' objects. The 'parent'
object is the next-least-specific object that exists in the relevant
registry, while the 'child' objects are the next-most-specific
objects that exist in the relevant registry. For example, for a
registry with the following four IP network objects:
192.0.2.0/24
Harrison & Singh Expires 9 April 2023 [Page 4]
Internet-Draft RDAP RIR Search October 2022
192.0.2.0/25
192.0.2.128/25
192.0.2.0/32
the parent object of 192.0.2.0/32 would be 192.0.2.0/25, the parent
object of 192.0.2.128/25 would be 192.0.2.0/24, the parent object of
192.0.2.0/25 would be 192.0.2.0/24, and 192.0.2.0/24 would have no
parent object. Conversely, the child objects for 192.0.2.0/24 would
be 192.0.2.0/25 and 192.0.2.128/25, for 192.0.2.0/25 192.0.2.0/32,
and for 192.0.2.128/25 and 192.0.2.0/32 there would be no child
objects.
In order to permit clients to locate the parent object for a given
object, an operator MAY include a link using the "up" link relation
that links to the parent object. Similarly, in order to permit
clients to locate the child objects for a given object, an operator
MAY include a link using the "down" link relation that when resolved,
returns a response that has the same format as a search for the
relevant object type containing all of the child objects for that
object. For example:
{
...
"links": [
...,
{
"value": "http://rdap.example.com/ip/192.0.2.0/25",
"rel": "up",
"href": "http://rdap.example.com/ip/192.0.2.0/24",
"type": "application/rdap+json"
},
{
"value": "http://rdap.example.com/ip/192.0.2.0/25",
"rel": "down",
"href": "http://rdap.example.com/ip-down/192.0.2.0/25",
"type": "application/rdap+json"
}
]
}
In the example above, the link target for the link with the "down"
relation is "http://rdap.example.com/ip-down/192.0.2.0/25". However,
the link structure used by a server for these links is not defined by
this specification, and clients MUST NOT make inferences about
supported behaviour by inspecting the structure of these links.

5. Reverse Search
RDAP reverse search is defined by
[I-D.ietf-regext-rdap-reverse-search]. That document limits reverse
search to domains, nameservers, and entities. This document extends
reverse search to cover IP networks and autonomous system numbers as
well, by incorporating the text from section 2 and additionally
permitting "searchable-resource-type" to be "ips" or "autnums".
6. RDAP Conformance
A server that supports all of the functionality specified in this
document MUST include the string literal "rir_search" in the
rdapConformance array in their response objects.
7. Privacy Considerations
The search functionality defined in this document may affect the
privacy of entities in the registry (and elsewhere) in various ways:
see [RFC6973] for a general treatment of privacy in protocol
specifications. Registry operators should be aware of the tradeoffs
that result from implementation of this functionality.
Many jurisdictions have laws or regulations that restrict the use of
"Personal Data", per the definition in [RFC6973]. Given that,
registry operators should ascertain whether the regulatory
environment in which they operate permits implementation of the
functionality defined in this document.
8. Security Considerations
[RFC7481] describes security requirements and considerations for RDAP
generally.
9. IANA Considerations
IANA is requested to register the following value in the RDAP
Extensions Registry:
* Extension identifier: rir_search
* Registry operator: Any
* Published specification: [this document]
* Contact: IETF <iesg@ietf.org>
Harrison & Singh Expires 9 April 2023 [Page 6]
Internet-Draft RDAP RIR Search October 2022
* Intended usage: This extension identifier is used for RIR-specific
search operations.
IANA is also requested to register the following value in the Link
Relations Registry:
* Relation Name: down
* Description: Refers to a set of child documents in a hierarchy of
documents.
* Reference: [this document]
