Introduction 77 The Internet Protocol version 4 (IPv4) [RFC0791] provides for 78 expansion of the protocol by supporting a number of "options" in the 79 variable-length IPv4 header. IPv4 options are identified by an 80 option "type" value, whose registration is managed by IANA [IANA-IP]. 81 A number of IPv4 options have become obsolete in practice, but have 82 never been formally deprecated. This document deprecates such IPv4 83 options, "cleaning up" the corresponding IANA registry. 85 This document also obsoletes [RFC1385], [RFC1393], [RFC1475], and 86 [RFC1770], and requests the RFC Editor to change their status to 87 "Historic". 89 2. Discussion of Deprecated Options 91 The following subsections discuss the details of options being 92 deprecated, and no other reference information has been found. 94 2.1. Stream ID 96 The Stream ID option is obsolete. It is specified in RFC 791 97 [RFC0791], and deprecated in Section 3.2.1.8 of RFC 1122 [RFC1122] 98 and Section 4.2.2.1 of RFC 1812 [RFC1812]. 100 2.2. Extended Internet Protocol 102 The Extended Internet Protocol option is defined in [RFC1385], and is 103 superseded by [RFC2460]. 105 2.3. Traceroute 107 The Traceroute option is defined in [RFC1393]. The Traceroute option 108 is defined as "experimental" and it was never widely deployed on the 109 public Internet. 111 2.4. ENCODE 113 This option was used for experimentation around IP-layer encryption. 114 No products are known to ever have shipped with support for this 115 option. 117 2.5. VISA 119 This option was part of an experiment [VISA87] [VISA89] at USC and 120 was never widely deployed. 122 2.6. Address Extension 124 The Address Extension option is defined in the Experimental 125 [RFC1475], and marked as IPv7. 127 2.7. Selective Directed Broadcast 129 The Selective Directed Broadcast option is originally defined in 130 [RFC1770]. 132 2.8. Dynamic Packet State 134 The Dynamic Packet State option was specified in 135 [I-D.stoica-diffserv-dps]. The aforementioned document was meant to 136 be published as "Experimental", but never became an RFC. 138 2.9. Upstream Multicast Pkt. 140 This option was originally specified in [draft-farinacci-bidir-pim]. 141 Its use was deprecated by [RFC5015], which employs a control plane 142 mechanism to solve the problem of doing upstream forwarding of 143 multicast packets on a multi-access LAN. 145 3. IANA Considerations 147 The "IP OPTION NUMBERS" registry [IANA-IP] contains the list of the 148 currently assigned IP option numbers. This registry also denotes an 149 deprecated IP Option Number by marking it with a single asterisk 150 ("*"). 152 This document formally deprecates the following options, and requests 153 IANA to mark them as such in the corresponding registry [IANA-IP]. 155 Copy Class Number Value Name Reference 156 ---- ----- ------ ----- ------------------------------- ------------ 157 1 0 8 136 SID - Stream ID [RFC791,JBP]* 158 1 0 14 142 VISA - Expermental Access Control [Estrin]* 159 0 0 15 15 ENCODE - ???

[Farinacci]* 167 The IP Options "MTU Probe" (MTUP, value 11) and "MTU Reply" (MTUR, 168 value 12) initially defined in [RFC1063] have already been deprecated 169 by [RFC1191]. 171 4. Changing the status of the corresponding RFCs to Historic 173 This document requests the RFC Editor to change the status of 174 [RFC1385], [RFC1393], [RFC1475], and [RFC1770] to "Historic". 176 5. Security Considerations 178 This document does not modify the security properties of the IPv4 179 Options being deprecated. However, formally deprecating these 180 options serves as a basis for e.g. providing advice about filtering 181 packets containing these options (as in 182 [I-D.ietf-opsec-ip-options-filtering]). 184 6. Acknowledgments 186 The authors would like to thank Ron Bonica for his guidance. 188 The authors would like to thank Ran Atkinson, Fred Baker, Deborah 189 Estrin, Dino Farinacci, Andrew Malis, Gene Tsudik, and Bill VerSteeg 190 for providing insights on some of the options being formally 191 deprecated by this document. 193 7.
