             Formally Deprecating Some ICMPv4 Message Types
                  draft-gp-obsolete-icmp-types-iana-01

Abstract

   A number of ICMPv4 message types have become obsolete in practice,
   but have never been formally deprecated.  This document deprecates
   such ICMPv4 message types, thus cleaning up the corresponding IANA
   registry.  Additionally, it updates RFC792 and RFC950, obsoletes
   RFC1788, and requests the RFC Editor to change the status of RFC1788
   to "Historic".

Internet-Draft      Deprecating Some ICMPv4 Messages        January 2013


1.  Introduction

   A number of ICMPv4 [RFC0792] message types have been specified over
   the years.  A number of these message types have become obsolete in
   practice, but have never been formally deprecated.  This document
   deprecates such ICMPv4 message types, "cleaning up" the corresponding
   IANA registry.  Additionally, it updates RFC792 and RFC950, obsoletes
   RFC1788, and requests the RFC Editor to change the status of RFC1788
   to "Historic".

   Section 2 discusses each of the obsoleted ICMPv4 messages.  Section 4
   requests the RFC Editor to change the status of RFC1788 to
   "Historic".


2.  Discussion of Deprecated ICMPv4 Message Types

   The following subsections discuss the details of those ICMPv4 message
   types being deprecated, based on publicly available information
   and/or information provided by the requester of the corresponding
   assignment.

2.1.  Alternate Host Address (Type 6)

   There is no publicly-available information about this message type.

2.2.  Information Request (Type 15)

   This message type is specified in [RFC0792].  However, other
   mechanisms (such as DHCP [RFC2131]) have superseded this message type
   for the purpose of host configuration.

2.3.  Information Reply (Type 16)

   This message type is specified in [RFC0792].  However, other
   mechanisms (such as DHCP [RFC2131]) have superseded this message type
   for the purpose of host configuration.

2.4.  Address Mask Request (Type 17)

   This message type is specified in [RFC0950], and was meant to provide
   a means to obtain the subnet mask.  However, other mechanisms (such
   as DHCP [RFC2131]) have superseded this message type for the purpose
   of host configuration.

2.5.  Address Mask Reply (Type 18)

   This message type is specified in [RFC0950], and was meant to provide
   a means to obtain the subnet mask.  However, other mechanisms (such
   as DHCP [RFC2131]) have superseded this message type for the purpose
   of host configuration.

2.6.  Traceroute (Type 30)

   This message type is specified in [RFC1393], and was meant to provide
   an alternative means to discover the path to a destination system.
   This message type has never been widely deployed, and the status of
   [RFC1393] has been changed to "Historic" by [RFC6814] and the
   corresponding option this message type relies on (Traceroute, Type
   82) has been formally obsoleted by [RFC6814].

2.7.  Datagram Conversion Error (Type 31)

   This message type was originally mean to report conversion errors in
   the TP/IX [RFC1475] protocol.  However, TP/IX was never widely
   implemented or deployed, and the status of [RFC1475] is "Historic".

2.8.  Mobile Host Redirect (Type 32)

   This message type was originally specified as part of an experimental
   protocol for IP Mobile Hosts [cmu-mobile].  However, it was never
   widely implemented or deployed.

2.9.  IPv6 Where-Are-You (Type 33)

   This message type was originally specified in
   [draft-simpson-ipv6-discov-formats] for the purpose of identification
   of adjacent IPv6 nodes.  It was never widely deployed or implemented.

2.10.  IPv6 I-Am-Here (Type 34)

   This message type was originally specified in
   [draft-simpson-ipv6-discov-formats] for the purpose of identification
   of adjacent IPv6 nodes.  It was never widely deployed or implemented.

2.11.  Mobile Registration Request (Type 35)

   This message type was originally meant for transparent routing of
   IPv6 datagrams to Mobile Nodes [draft-simpson-ipv6-mobility].  It was
   never widely deployed or implemented.

2.12.  Mobile Registration Reply (Type 36)

   This message type was originally meant for transparent routing of
   IPv6 datagrams to Mobile Nodes [draft-simpson-ipv6-mobility].  It was
   never widely deployed or implemented.

2.13.  Domain Name Request (Type 37)

   This message type was originally specified in [RFC1788] for the
   purpose of learning the Fully Qualified Domain Name associated with
   an IP address.  This message type was never widely deployed or
   implemented.

2.14.  Domain Name Reply (Type 38)

   This message type was originally specified in [RFC1788] for the
   purpose of learning the Fully Qualified Domain Name associated with
   an IP address.  This message type was never widely deployed or
   implemented.

2.15.  SKIP (Type 39)

   This message type was originally specified in
   [draft-ietf-ipsec-skip-adp] for informing supported capabilities in
   the SKIP [draft-ietf-ipsec-skip] protocol.  This message type was
   never widely deployed or implemented.


3.  IANA Considerations

   The "Internet Control Message Protocol (ICMP) Parameters" registry
   [IANA-ICMP] contains the list of the currently assigned ICMP message
   Types.

   This document formally deprecates the following ICMP message Types,
   and requests IANA to mark them as such in the corresponding registry
   [IANA-ICMP]:

   o  Alternate Host Address (Type 6)

   o  Information Request (Type 15)

   o  Information Reply (Type 16)

   o  Address Mask Request (Type 17)

   o  Address Mask Reply (Type 18)

   o  Traceroute (Type 30)

   o  Datagram Conversion Error (Type 31)

   o  Mobile Host Redirect (Type 32)

   o  IPv6 Where-Are-You (Type 33)

   o  IPv6 I-Am-Here (Type 34)

   o  Mobile Registration Request (Type 35)

   o  Mobile Registration Reply (Type 36)

   o  Domain Name Request (Type 37)

   o  Domain Name Reply (Type 38)

   o  SKIP (Type 39)

      The ICMPv4 Source Quench Message (Type 4) has already been
      deprecated by [RFC6633].


4.  Changing the status of RFC1788 to Historic

   This document requests the RFC Editor to change the status of
   [RFC1788] to "Historic".

      The status of [RFC1385] and [RFC1393] is already "Historic".  The
      status of other RFCs (such as [RFC0792] and [RFC0950] is not
      changed since other parts of these documents are still current.


5.  Security Considerations

   This document does not modify the security properties of the ICMPv4
   message types being deprecated.  However, formally deprecating these
   message types serves as a basis for e.g. filtering these packets.


6.  Acknowledgments

   The authors would like to thank Ron Bonica and Joel Halpern for their
   guidance.
