    <abstract>


<t>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.</t>

<section anchor="introduction" title="Introduction">

<t>The “int” top-level domain <xref target="RFC1591"/> is a specialized domain
designated for intergovernmental organizations, which are organizations
established by international treaties between or among national
governments.</t>

<t>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
<xref target="RFC3172"/>. In conjunction with this change, the eligibility for “int”
domains was limited to only intergovernmental treaty organizations.</t>

<t>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.</t>

</section>
<section anchor="historical-infrastructural-uses" title="Historical infrastructural uses">

<t>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.</t>

<section anchor="atmaint" title="atma.int">

<t>The atma.int domain was experimentally defined to implement address
lookups for Asynchronous Transfer Mode (ATM), including ATM End System
Addresses (AESAs). <xref target="ANS"/></t>

</section>
<section anchor="ip4int" title="ip4.int">

<t>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
<xref target="RFC1035"/>.</t>

</section>
<section anchor="ip6int" title="ip6.int">

<t>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been replaced by ip6.arpa for this purpose <xref target="RFC4159"/>.</t>

</section>
<section anchor="nsapint" title="nsap.int">

<t>The nsap.int domain name was specified to experimentally map Open
Systems Interconnection (OSI) Network Service Access Points to domain
names <xref target="RFC1706"/>.</t>

</section>
<section anchor="rdiint" title="rdi.int">

<t>The rdi.int domain name experimentally mapped OSI Inter-Domain Routing
Protocol’s Routing Domain Identifiers <xref target="ISO10747"/> to the domain name
system.</t>

</section>
<section anchor="regint" title="reg.int">

<t>The reg.int domain name hosted an experimental mechanism for publishing
IANA registration values in the domain name system.</t>

</section>
<section anchor="tpcint" title="tpc.int">

<t>The tpc.int domain name hosted an experimental remote printing
service that served as a gateway between Internet mail and facsimile
transmission <xref target="RFC1528"/>.</t>

</section>
</section>
<section anchor="updates-to-other-rfc-series-documents" title="Updates to other RFC Series documents">

<section anchor="rfc-1528" title="RFC 1528">

<t>The specification for tpc.int <xref target="RFC1528"/> should be deemed historic
as it no longer functions as described in the document.</t>

</section>
<section anchor="rfc-1706" title="RFC 1706">

<t>The specification for nsap.int <xref target="RFC1706"/> should be deemed historic
as it no longer functions as described in the document.</t>

</section>
</section>
<section anchor="iana-considerations" title="IANA Considerations">

<t>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.</t>

</section>
<section anchor="security-considerations" title="Security Considerations">

<t>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.</t>

<t>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.</t>

</section>
<section anchor="additional-information" title="Additional Information">

<t>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.</t>

<t>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.</t>
