All Rights Reserved. 36 Abstract 38 Prior to the publication of RFC2489 (which was updated by RFC2939), 39 several option codes were assigned to proposed DHCP options that were 40 subsequently never used. This document lists those unused option 41 codes and will be used to confirm that these option codes can be 42 reused for other DHCP options in the future. 44 1. Introduction 46 This document lists the unused DHCP option codes from the IANA list 47 of BOOTP and DHCP option codes [1]. Each option code includes any 48 known documentation and contact information from the IANA list. 50 2. Unused Option Codes 52 The option codes listed in this section are to be returned to IANA 53 for reassignment to new options. 55 2.1 Service Location Protocol Naming Authority 57 Code: 80 59 Name: Service Location Protocol Naming Authority 61 Defined in: (expired Internet-Draft) 63 Contact: Charlie Perkins 65 Reason to recover: Never published as standard 67 2.2 Relay Agent Options 69 Codes: 83, 84 71 Name: Relay Agent Options 73 Defined in: Early draft of RFC3046 [2] 75 Contact: (none) 77 Reason to recover: Not defined in RFC3046 as published 79 2.3 IEEE 1003.1 POSIX Timezone 81 Code: 88 83 Name: IEEE 1003.1 POSIX Timezone 85 Defined in: (expired Internet-Draft) 87 Contact: Mike Carney 89 Reason to recover: Never published as standard 91 2.4 FQDNs in DHCP Options 93 Code: 89 94 Name: FQDNs in DHCP Options 96 Defined in: (expired Internet-Draft) 98 Contact: Ralph Droms 100 Reason to recover: Never published as standard 102 2.5 VINES TCP/IP Server 104 Code: 91 106 Name: VINES TCP/IP Server 108 Defined in: (none) 110 Contact: (none) 112 Reason to recover: Never published as Internet-Draft 114 2.6 Server Selection 116 Code: 92 118 Name: Server Selection 120 Defined in: (none) 122 Contact: (none) 124 Reason to recover: Never published as Internet-Draft 126 2.7 LDAP Servers 128 Code: 95 130 Name: LDAP Servers 132 Defined in: (none) 134 Contact: (none) 136 Reason to recover: Never published as Internet-Draft 138 2.8 IPv6 Transition 140 Code: 96 142 Name: IPv6 Transition 144 Defined in: (expired Internet-Draft) 146 Contact: Dan Harrington 148 Reason to recover: Never published as standard 150 2.9 Printer Name 152 Code: 100 154 Name: Printer Name 156 Defined in: (none) 158 Contact: (none) 160 Reason to recover: Never published as Internet-Draft 162 2.10 Multicast Assignment through DHCP 164 Code: 101 166 Name: Multicast Assignment through DHCP 168 Defined in: (expired Internet-Draft) 170 Contact: Baiju Patel, Munil Shah 172 Reason to recover: Never published as standard 174 2.11 Swap Path 176 Code: 108 178 Name: Swap Path 180 Defined in: (none) 182 Contact: (none) 183 Reason to recover: Never published as Internet-Draft 185 2.12 IPX Compatibility 187 Code: 110 189 Name: IPX Compatibility 191 Defined in: (none) 193 Contact: Juan Luciani 195 Reason to recover: Never published as Internet-Draft 197 2.13 Netinfo Parameters 199 Codes: 112, 113 201 Name: Netinfo Address, Netinfo Tag 203 Defined in: (none) 205 Contact: Marc Majka 207 Reason to recover: Never published as Internet-Draft 209 2.14 URL 211 Code: 114 213 Name: URL 215 Defined in: (none) 217 Contact: Vinod Valloppillil 219 Reason to recover: Never published as Internet-Draft 221 2.15 Failover 223 Code: 115 225 Name: Failover 226 Defined in: Early revisions of "DHCP Failover Protocol" [3] 228 Contact: Kim Kinnear 230 Reason to recover: Current version of "DHCP Failover Protocol" does 231 not use a DHCP option 233 3. Option codes used in PXE Specification 235 The following option codes are used in the "Preboot Execution 236 Environment (PXE) Specification, Version 2.1" [4]. However, none of 237 these option codes have been specified as a Standards-track RFC. 239 3.1 Client System 241 Code: 93 243 Name: Client System 245 Defined in: (none) 247 Contact: (none) 249 Reason to recover: Never published as Internet-Draft 251 3.2 Client NDI 253 Code: 94 255 Name: Client NDI 257 Defined in: (none) 259 Contact: (none) 261 Reason to recover: Never published as Internet-Draft 263 3.3 UUID/GUID Client Identifier 265 Code: 97 267 Name: UUID/GUID Client Identifier 269 Defined in: (expired Internet-Draft) 270 Contact: Dan Harrington 272 Reason to recover: Never published as standard 274 4. Option Code Extensions 276 Note that these option codes are identified in draft-volz-dhc- 277 extended-optioncodes-00 [6] as part of a mechanism for extending the 278 set of option codes available to DHCP. If these option codes are not 279 used for DHCP option code extension, they will be returned to IANA 280 for reassignment to other DHCP options. 282 Codes: 126, 127 284 Name: Option Code Extensions 286 Defined in: (expired Internet-Draft) 288 Contact: Ralph Droms 290 Reason to recover: Never published as standard; note that these 291 option codes are mentioned as 293 5. Already Returned for Reassignment 295 The option codes 99, 102-107, 109 and 111 have already been returned 296 for reassignment to future DHCP options. 298 6. IANA Considerations 300 When this document has been published as an Informational RFC, IANA 301 will be requested to return the unused DHCP option codes to the list 302 of available option codes. These option codes may be reassigned to 303 new DHCP options, according to the procedures in RFC 2939 [5]. 305 References 307 [1] Assigned Numbers Editor, IANA., "BOOTP and DHCP Parameters", 308 http://www.iana.org/assignments/bootp-dhcp-parameters, 309 February 2003. 311 [2] Patrick, M., "DHCP Relay Agent Information Option", RFC 3046, 312 January 2001. 314 [3] Droms, R., Kinnear, K., Stapp, M., Volz, B., Gonczi, S., Rabil, 315 G., Dooley, M. and A.
