                Deprecating infrastructure "int" domains


   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.

Internet-Draft         Infrastructure .int domains            March 2021

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.

   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.

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.


   The domain was experimentally defined to implement address
   lookups for Asynchronous Transfer Mode (ATM), including ATM End
   System Addresses (AESAs).  [ANS]


   The domain was described as providing an alternative to in- domain for mapping host IPv4 addresses to host names.  The domain zone continues to be administered for this
   purpose [RFC1035].

   The domain was similarly delegated, and subsequently removed
   from the "int" zone, having been replaced by for the purpose
   of mapping host IPv6 addresses to host names [RFC4159].

   The domain name was specified to experimentally map Open
   Systems Interconnection (OSI) Network Service Access Points to domain
   names [RFC1706].


   The domain name experimentally mapped OSI Inter-Domain
   Routing Protocol's Routing Domain Identifiers [ISO10747] to the
   domain name system.


   The domain name hosted an experimental mechanism for
   publishing IANA registration values in the domain name system.


   The domain name hosted an experimental remote printing
   service that served as a gateway between Internet mail and facsimile
   transmission [RFC1528].
