Deprecating infrastructure "int" domains
draft-davies-int-historic-05
Abstract
The document deprecates the use of any "int" domain names that were
designated for infrastructure purposes by the IETF, and identifies
them for removal from the "int" top-level domain. Any implementation
that involves these domains should be considered deprecated. This
document also requests moving the status of RFC 1528 and RFC 1706 to
historic.

1. Introduction
The "int" top-level domain [RFC1591] is a specialized domain
designated for intergovernmental organizations, which are
organizations established by international treaties between or among
national governments.
Historically, the "int" domain was also used for Internet
infrastructure related purposes. This practice ended in 2001 when
the "arpa" domain was declared the appropriate home for
infrastructural identifier spaces [RFC3172]. In conjunction with
this change, the eligibility for "int" domains was limited to only
intergovernmental treaty organizations.

Internet-Draft Infrastructure .int domains November 2022
The documented uses of infrastructural identifiers in the "int"
domain were largely experimental and are now in practice obsolete.
This document requests moving the related specifications to historic
status, along with removing any associated delegations from the "int"
zone in the domain name system.
2. Historical infrastructural uses
The following domains were used for infrastructural identifier
purposes that are now considered historic. Although each of these
names was either delegated or documented at one time, the parties
administering them have long since stopped using them.
2.1. atma.int
The atma.int domain was experimentally defined to implement address
lookups for Asynchronous Transfer Mode (ATM), including ATM End
System Addresses (AESAs). [ANS]
2.2. ip4.int
The ip4.int domain was described as providing an alternative to in-
addr.arpa domain for mapping host IPv4 addresses to host names. The
in-addr.arpa domain zone continues to be administered for this
purpose [RFC1035].
2.3. ip6.int
The ip6.int domain was originally delegated for mapping host IPv6
addresses to host names. It was subsequently removed from the "int"
zone, having been replaced by ip6.arpa for this purpose [RFC4159].
2.4. nsap.int
The nsap.int domain name was specified to experimentally map Open
Systems Interconnection (OSI) Network Service Access Points to domain
names [RFC1706].
2.5. rdi.int
The rdi.int domain name experimentally mapped OSI Inter-Domain
Routing Protocol's Routing Domain Identifiers [ISO10747] to the
domain name system.
2.6. reg.int
The reg.int domain name hosted an experimental mechanism for
publishing IANA registration values in the domain name system.

Internet-Draft Infrastructure .int domains November 2022
2.7. tpc.int
The tpc.int domain name hosted an experimental remote printing
service that served as a gateway between Internet mail and facsimile
transmission [RFC1528].
3. Updates to other RFC Series documents
3.1. RFC 1528
The specification for tpc.int [RFC1528] should be deemed historic as
it no longer functions as described in the document.
3.2. RFC 1706
The specification for nsap.int [RFC1706] should be deemed historic as
it no longer functions as described in the document.
4. IANA Considerations
The IANA shall coordinate the removal of any of the historical "int"
domains discussed in this document that are still delegated in the
"int" zone.
5. Security Considerations
Some old systems might have one or more subdomains of these names
hardwired and expect a positive response for at least the second-
level domain. This is, of course, true for any name in the DNS and
should not be the sole basis to retain obsolete names.
Existing applications should eliminate any reliance upon these zones
for their historic purpose. The operator of the "int" domain should
be cautious about any potential re-use of these domains for
intergovernmental treaty organizations.
6. Additional Information
This document is the result of an comprehensive inventory conducted
by the IANA team of .int domains to accurately establish and record
their purpose based on historical documentation. As part of this
inventory, the domains delegated for infrastructure identifier
related purposes were studied. Query patterns in the DNS for these
domains were analyzed and judged to be insignificant, and preliminary
outreach was conducted to the contacts for the associated domains.
The assessment concluded that these domains are highly likely to be
obsolete and this document is intended to formalize that assessment.

Internet-Draft Infrastructure .int domains November 2022
There are a small number of existing "int" domains nominally for
"international databases" that are not defined by any standards
documentation, and are assigned to entities rather than for an
identifier purpose. While they would not qualify for a "int" domain
under current criteria, their disposition is beyond the scope of this
memo.
