1. Introduction
[RFC8805] and [RFC9632] detail the IP geolocation feed (commonly
known as 'geofeed') file format and associated access mechanisms.
While [RFC9632] describes how a registry can make geofeed URLs
available by way of a Routing Policy Specification Language (RPSL)
[RFC2622] service, the Regional Internet Registries (RIRs) have
deployed Registration Data Access Protocol (RDAP) ([RFC7480],
[RFC7481], [RFC9082], [RFC9083]) services as successors to RPSL for
Internet number resource registrations, and maintaining feature
parity between the two services supports client transition from RPSL
to RDAP in this context. To that end, this document specifies how
geofeed URLs can be accessed through RDAP. It defines a new RDAP
extension, "geofeed1", for indicating that an RDAP server hosts
geofeed URLs for its IP network objects, as well as a new media type
and a new link relation type for the associated link objects.
Fetching and making use of geofeed data is out of scope for the
purposes of this document. See [RFC8805] and [RFC9632] for further
details.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in
BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all
capitals, as shown here.
Indentation and whitespace in examples are provided only to
illustrate element relationships, and they are not a required feature
of this specification.
"..." in examples is used as shorthand for elements defined outside
of this document.
2. Specification
2.1. Media Type for a Geofeed Link
[RFC9632] requires a geofeed file to be a UTF-8 [RFC3629] comma-
separated values (CSV) file, with a series of "#" comments at the end
for the optional Resource Public Key Infrastructure (RPKI, [RFC6480]) (RPKI) [RFC6480]
signature. At first glance, the "text/csv" media type seems like a
good candidate for a geofeed file, since it supports the "#" comments
needed for including the RPKI signature.
However, although the CSV geofeed data could be viewed directly by a
user such that the "text/csv" media type was appropriate, the most
common use case will involve it being processed by some sort of
application first, in order to facilitate subsequent IP address
lookup operations. Therefore, using a new "application" media type
with a "geofeed" subtype (Section 4.2.5 of [RFC6838]) for the geofeed
data is preferable to using "text/csv".
To that end, this document registers a new "application/geofeed+csv"
media type in the IANA Media Types Registry "Media Types" registry (see Section 6.3), and
a new "+csv" suffix in the IANA Structured "Structured Syntax Suffixes Registry Suffixes" registry
(see Section 6.4).
2.2. Geofeed Link
An RDAP server that hosts geofeed URLs for its IP network objects
(Section 5.4 of [RFC9083]) may include link objects for those geofeed
URLs in IP network objects in its responses. These link objects are
added to the "links" member of each object (Section 4.2 of
[RFC9083]).
In RDAP, the "value", "rel", and "href" JSON members are required for
any link object. Additionally, for a geofeed link object, the "type"
JSON member is RECOMMENDED. The geofeed-specific components of a
link object are like so:
* "rel" --
"rel": The link relation type is set to "geofeed". This is a new
link relation type for IP geolocation feed data, registered in the
IANA Link Relations Registry "Link Relations" registry (see Section 6.2) by this document.
* "href" --
"href": The target URL is set to the HTTPS URL of the geofeed file
(Section 6 of [RFC9632]) for an IP network.
* "type" --
"type": "application/geofeed+csv" (see Section 2.1).
An IP network object returned by an RDAP server MAY contain zero or
more geofeed link objects, though typically an IP network will have
either no such link objects zero or only one. The scenario where more than one geofeed
link object could be returned is when the server is able to represent
that data in multiple languages. In such a case, the server SHOULD
provide "hreflang" members for the geofeed link objects. Except for
the multiple-languages scenario, the server SHOULD NOT return more
than one geofeed link object.
2.3. Extension Identifier
This document defines a new extension identifier, "geofeed1", for use
by servers that host geofeed URLs for their IP network objects and
include geofeed URL link objects in their responses to clients in
accordance with Section 2.2. A server that uses this extension
identifier MUST include it in the "rdapConformance" array
(Section 4.1 of [RFC9083]) for any lookup or search response
containing an IP network object, as well as in the help response.
Here is an elided example for of this inclusion:
{
"rdapConformance": [ "rdap_level_0", "geofeed1", ... ],
...
}
If the server includes "geofeed1" in the "rdapConformance" array,
then for any response concerning a particular IP network object for
which the server possesses a geofeed URL and is able to return it to
the client (i.e. (i.e., the server is not compelled to omit it due to
regulatory constraints or similar), the server MUST include a
corresponding geofeed link object in the response.
An RDAP server may make use of the "application/geofeed+csv" media
type and the "geofeed" link relation defined in this specification in
its responses without including the "geofeed1" extension identifier
in those responses, because RDAP servers are free to use any
registered media type or link relation in a standard response without
implementing any particular extension. The additional value of
including the extension identifier in the "rdapConformance" array is
that it signals to the client that the server hosts geofeed URLs for
its IP network objects. This is useful where a client receives an IP
network object without a geofeed link object, because in that case
the client can infer that no geofeed data is available for that
object, since the server would have provided it if it were available.
Although a server may use registered media types in its link objects
without any restrictions, it is useful to define new RDAP extensions
for those media types in order for the server to communicate to
clients that it will make data for that type accessible, in accessible. This is the
same
way that as what the server does with the "geofeed1" extension
identifier.
The "1" in "geofeed1" denotes that this is version 1 of the geofeed
extension. New versions of the geofeed extension will use different
extension identifiers.
2.4. Example
The following is an elided example of an IP network object with a
geofeed link object:
{
"objectClassName": "ip network",
"handle": "XXXX-RIR",
"startAddress": "2001:db8::",
"endAddress": "2001:db8:0:ffff:ffff:ffff:ffff:ffff",
"ipVersion": "v6",
"name": "NET-RTR-1",
"type": "DIRECT ALLOCATION",
"country": "AU",
"parentHandle": "YYYY-RIR",
"status": [ "active" ],
"links":
[
{
"value": "https://example.net/ip/2001:db8::/48",
"rel": "self",
"href": "https://example.net/ip/2001:db8::/48",
"type": "application/rdap+json"
},
{
"value": "https://example.net/ip/2001:db8::/48",
"rel": "geofeed",
"href": "https://example.com/geofeed",
"type": "application/geofeed+csv"
},
...
],
...
}
3. Operational Considerations
When an RDAP client performs an IP network lookup, per Section 3.1.1
of [RFC9082], the RDAP server is required to return the most-specific
IP network object that covers the IP address range provided by the
client. That IP network object may not have an associated geofeed
link, but it is possible that a less-specific IP network object does
have such a link. Clients attempting to retrieve geofeed data for a
given IP address range via RDAP should consider whether to retrieve
the parent object for the initial response (and so on, recursively)
in the event that the initial response does not contain geofeed data.
Conversely, server operators should consider interface options for
resource holders in order to support the provisioning of geofeed
links for all networks covered by the associated data.
It is common for a resource holder to maintain a single geofeed file
containing the geofeed data for all of their resources. The resource
holder then updates each of their network object registrations to
refer to that single geofeed file. As with geofeed references in
inetnum objects (per [RFC9632]), clients who find a geofeed link
object within an IP network object and opt to retrieve the data from
the associated link MUST ignore any entry where the entry's IP
address range is outside the IP network object's address range.
Section 3.2 of [RFC8805] recommends that consumers of geofeed data
verify that the publisher of the data is authoritative for the
relevant resources. The RDAP bootstrap process ([RFC9224]) [RFC9224] helps
clients with this recommendation, since a client following that
process will be directed to the RDAP server that is able to make
authoritative statements about the disposition of the relevant
resources.
To prevent undue load on RDAP and geofeed servers, clients fetching
geofeed data using these mechanisms MUST NOT do frequent real-time
lookups. See Section 6 of [RFC9632] for further details.
4. Privacy Considerations
All the privacy considerations from Section 7 of [RFC9632] apply to
this document. In particular, the service provider publishing the
geofeed file MUST take care not to expose the location of any
individual.
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.
5. Security Considerations
Section 6 of [RFC9632] documents several security considerations that
are equally relevant in the RDAP context.
A geofeed file MUST be referenced with an HTTPS URL, per Section 6 of
[RFC9632]. The geofeed file may also contain an RPKI signature, per
Section 5 of [RFC9632].
Besides that, this document does not introduce any new security
considerations past those already discussed in the RDAP protocol
specifications ([RFC7481], [RFC9560]).
