Formally Deprecating some IPv4 Options
draft-gp-intarea-obsolete-ipv4-options-iana-02
Abstract
A number of IPv4 options have become obsolete in practice, but have
never been formally deprecated. This document deprecates such IPv4
options, thus cleaning up the corresponding IANA registry, and
serving as a basis for providing advice about the filtering of
packets containing these options. Additionally, it requests that the
status of the corresponding RFCs be changed to "Historic".

Internet-Draft Deprecating some IPv4 Options September 2012
1. Introduction
The Internet Protocol version 4 (IPv4) [RFC0791] provides for
expansion of the protocol by supporting a number of "options" in the
variable-length IPv4 header. IPv4 options are identified by an
option "type" value, whose registration is managed by IANA [IANA-IP].
A number of IPv4 options have become obsolete in practice, but have
never been formally deprecated. This document deprecates such IPv4
options, "cleaning up" the corresponding IANA registry.
This document also obsoletes [RFC1385], [RFC1393], [RFC1475], and
[RFC1770], and requests the RFC Editor to change their status to
"Historic".
2. Discussion of Deprecated Options
The following subsections discuss the details of options being
deprecated, and no other reference information has been found.
2.1. Stream ID
The Stream ID option is obsolete. It is specified in RFC 791
[RFC0791], and deprecated in Section 3.2.1.8 of RFC 1122 [RFC1122]
and Section 4.2.2.1 of RFC 1812 [RFC1812].
2.2. Extended Internet Protocol
The Extended Internet Protocol option is defined in [RFC1385], and is
superseded by [RFC2460].
2.3. Traceroute
The Traceroute option is defined in [RFC1393]. The Traceroute option
is defined as "experimental" and it was never widely deployed on the
public Internet.
2.4. ENCODE
This option was used for experimentation around IP-layer encryption.
No products are known to ever have shipped with support for this
option.
2.5. VISA
This option was part of an experiment [VISA87] [VISA89] at USC and
was never widely deployed.

Internet-Draft Deprecating some IPv4 Options September 2012
2.6. Address Extension
The Address Extension option is defined in the Experimental
[RFC1475], and marked as IPv7.
2.7. Selective Directed Broadcast
The Selective Directed Broadcast option is originally defined in
[RFC1770].
2.8. Dynamic Packet State
The Dynamic Packet State option was specified in
[I-D.stoica-diffserv-dps]. The aforementioned document was meant to
be published as "Experimental", but never became an RFC.
2.9. Upstream Multicast Pkt.
This option was originally specified in [draft-farinacci-bidir-pim].
Its use was deprecated by [RFC5015], which employs a control plane
mechanism to solve the problem of doing upstream forwarding of
multicast packets on a multi-access LAN.
3. IANA Considerations
The "IP OPTION NUMBERS" registry [IANA-IP] contains the list of the
currently assigned IP option numbers. This registry also denotes an
deprecated IP Option Number by marking it with a single asterisk
("*").
This document formally deprecates the following options, and requests
IANA to mark them as such in the corresponding registry [IANA-IP].
Copy Class Number Value Name Reference
---- ----- ------ ----- ------------------------------- ------------
1 0 8 136 SID - Stream ID [RFC791,JBP]*
1 0 14 142 VISA - Expermental Access Control [Estrin]*
0 0 15 15 ENCODE - ??? [VerSteeg]*
1 0 17 145 EIP - Extended Internet Protocol[RFC1385]*
0 2 18 82 TR - Traceroute [RFC1393]*
1 0 19 147 ADDEXT - Address Extension [Ullmann IPv7]*

1 0 23 151 DPS - Dynamic Packet State [Malis]*
1 0 24 152 UMP - Upstream Multicast Pkt. [Farinacci]*
The IP Options "MTU Probe" (MTUP, value 11) and "MTU Reply" (MTUR,
Pignataro & Gont Expires March 27, 2013 [Page 4]
Internet-Draft Deprecating some IPv4 Options September 2012
value 12) initially defined in [RFC1063] have already been deprecated
by [RFC1191].
4. Changing the status of the corresponding RFCs to Historic
This document requests the RFC Editor to change the status of
[RFC1385], [RFC1393], [RFC1475], and [RFC1770] to "Historic".
5. Security Considerations
This document does not modify the security properties of the IPv4
Options being deprecated. However, formally deprecating these
options serves as a basis for e.g. providing advice about filtering
packets containing these options (as in
[I-D.ietf-opsec-ip-options-filtering]).
6. Acknowledgments
The authors would like to thank Ron Bonica for his guidance.
The authors would like to thank Ran Atkinson, Fred Baker, Deborah
Estrin, Dino Farinacci, Andrew Malis, Gene Tsudik, and Bill VerSteeg
for providing insights on some of the options being formally
deprecated by this document.
