Internet-Draft
The document marks as historic any “int” domain names that were
designated for infrastructure purposes, and identifies them for removal
from the “int” top-level domain. Any implementation that involves these
domains should be considered deprecated. This document also marks
RFC 1528 and RFC 1706 as historic.
The “int” top-level domain 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
. In conjunction with this change, the eligibility for “int”
domains was limited to only intergovernmental treaty organizations.
The documented uses of infrastructural identifiers in the “int” domain
were largely experimental and in practice obsolete. This document
formalizes moving the related specifications to historic status, along
with removing any associated delegations from the “int” zone in the
domain name system.
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.
The atma.int domain was experimentally defined to implement address
lookups for Asynchronous Transfer Mode (ATM), including ATM End System
Addresses (AESAs).
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
.
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been replaced by ip6.arpa for this purpose .
The nsap.int domain name was specified to experimentally map Open
Systems Interconnection (OSI) Network Service Access Points to domain
names .
The rdi.int domain name experimentally mapped OSI Inter-Domain Routing
Protocol’s Routing Domain Identifiers to the domain name
system.
The reg.int domain name hosted an experimental mechanism for publishing
IANA registration values in the domain name system.
The tpc.int domain name hosted an experimental remote printing
service that served as a gateway between Internet mail and facsimile
transmission .
The specification for tpc.int should be deemed historic
as it no longer functions as described in the document.
The specification for nsap.int should be deemed historic
as it no longer functions as described in the document.
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.
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.
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.
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.
Domain names - implementation and specification
This RFC is the revised specification of the protocol and format used in the implementation of the Domain Name System. It obsoletes RFC-883. This memo documents the details of the domain name client - server communication.
Principles of Operation for the TPC.INT Subdomain: Remote Printing -- Technical Procedures
This memo describes a technique for "remote printing" using the Internet mail infrastructure. In particular, this memo focuses on the case in which remote printers are connected to the international telephone network. This memo defines an Experimental Protocol for the Internet community. It does not specify an Internet standard.
Domain Name System Structure and Delegation
This memo provides some information on the structure of the names in the Domain Name System (DNS), specifically the top-level domain names; and on the administration of domains. This memo provides information for the Internet community. This memo does not specify an Internet standard of any kind.
DNS NSAP Resource Records
This document defines the format of one new Resource Record (RR) for the DNS for domain name-to-NSAP mapping. The RR may be used with any NSAP address format. This memo provides information for the Internet community. This memo does not specify an Internet standard of any kind.
Management Guidelines & Operational Requirements for the Address and Routing Parameter Area Domain ("arpa")
This memo describes the management and operational requirements for the address and routing parameter area ("arpa") domain. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
Deprecation of "ip6.int"
This document advises of the deprecation of the use of "ip6.int" for Standards Conformant IPv6 implementations. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
