RFC 3632 VeriSign RRP v2.0.0 November 2003

1. Introduction

The Network Solutions, Inc. (NSI) Registry Registrar Protocol (RRP)
was developed by NSI in 1998 and 1999 to allow multiple registrars to
provide second level Internet domain name registration services in
the top level domains (TLDs) administered by the NSI TLD registry.
Version 1.1.0 of the NSI RRP was published as Informational RFC 2832
[2] in May 2000. This document describes changes to RFC 2832 that
specify version 2.0.0 of the protocol.

Conventions Used In This Document

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL
NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL"
in this document are to be interpreted as described in BCP 14, RFC
2119 [1].

In examples, "C:" represents lines sent by a protocol client and
"S:" represents lines returned by a protocol server.

2. Protocol Updates

This specification describes several modifications to RFC 2832 [2]:
two new response codes have been added, domain TRANSFER command
processing has been updated to allow a client to cancel a requested
domain transfer, and support for IPv6 name server addresses has been
added.

2.1. Response Codes

Section 5.1 of RFC 2832 [2] has been updated to include two
additional error response codes.

510 Invalid encoding

The value of a domain name or name server entity contains invalid
ASCII compatible encoding used to represent an internationalized
domain or host name. The encoding is checked and verified in two
situations: when registering an internationalized domain name or name
server name, and when changing the name of a name server and the new
name of the server is internationalized.

Hollenbeck, et al. Informational [Page 2]

RFC 3632 VeriSign RRP v2.0.0 November 2003

Section 5.2 of RFC 2832 [2] has been updated to include response code
510 as a possible error value returned from the ADD command:

Command: ADD
Success: 200, 220
Failure: 420, 421, 500, 502, 503, 504, 505, 507, 508, 510, 520, 531,
535, 540, 541, 545, 546, 547, 549, 550, 554

557 Name server locked

An attempt has been made to modify or delete a name server that is
hosting a TLD in the root zone. Modifications to the root zone can
only be made with the approval of the U.S. Department of Commerce and
IANA, so if the registrar absolutely needs to modify or delete such a
name server, the action needs to be coordinated through the registry
operator using an out-of-band communications channel.

Section 5.2 of RFC 2832 [2] has been updated to include response code
557 as a possible error value returned from the DEL and MOD commands:

Command: DEL
Success: 200, 220
Failure: 420, 421, 500, 502, 503, 504, 505, 507, 508, 520, 531, 532,
533, 541, 544, 545, 547, 549, 551, 552, 553, 557

Command: MOD
Success: 200, 220
Failure: 420, 421, 500, 502, 503, 504, 505, 507, 508, 510, 520, 531,
535, 540, 541, 542, 543, 544, 545, 547, 549, 550, 551, 552, 553, 557

2.2. TRANSFER Command Update

Section 4.3.10 of RFC 2832 [2] has been updated to include an
additional TRANSFER command processing option.

Old text:

Authorized User: All registrars MAY use the TRANSFER command to
request the transfer of registration service authority to the
requesting registrar. Only the current sponsoring registrar of a
domain name may explicitly approve or reject a requested transfer.
The registry MAY implicitly approve or reject requested transfers
after a fixed amount of time.

Hollenbeck, et al. Informational [Page 3]

RFC 3632 VeriSign RRP v2.0.0 November 2003

New text:

Authorized User: All registrars MAY use the TRANSFER command to
request transfer of registration service authority to the requesting
registrar. Only the current sponsoring registrar of a domain name
may explicitly approve a requested transfer. The current sponsoring
registrar MAY explicitly reject a requested transfer. The registry
MAY implicitly approve or reject requested transfers after a fixed
amount of time. The requesting registrar MAY cancel a pending
request, but the request to cancel the transfer MUST be sent before
it has been explicitly approved or rejected by the current sponsoring
registrar or it has been implicitly approved or rejected by the
registry.

Example:

A registrar cancels a previously requested domain transfer:

C:transfer<crlf>
C:-Approve:No<crlf>
C:EntityName:Domain<crlf>
C:DomainName:example.com<crlf>
C:.<crlf>
S:200 Command completed successfully<crlf>
S:.<crlf>

2.3. IPv6 Name Server Addresses

Section 7 of RFC 2832 [2] has been updated to include support for
name servers using IPv6 addresses. IPv6 addressing architecture is
described in RFC 3513 [3]. This ABNF [4] grammar supplements the
grammar defined in RFC 2832.

; Lexical Tokens

hexdigit = digit / %X41-46 / %x61-66 ; 0-9 / A-F / a-f

doubleoctet = 1*4hexdigit

docolon = doubleoctet colon

colondo = colon doubleoctet

ip-address = ip-address-v4 / ip-address-v6

; ipv4 addresses
ip-address-v4 = 1*3digit dot 1*3digit dot 1*3digit dot 1*3digit

Hollenbeck, et al. Informational [Page 4]

RFC 3632 VeriSign RRP v2.0.0 November 2003

ip-address-v6 = ip-address-v6-standard / ip-address-v6-compressed
; Standard form of IPv6 addresses
; 8 hexdigit strings of length 1-4 separated by colons
;
; Eg: 10AA:0:0:00:8:800:200C:417A

ip-address-v6-standard = doubleoctet 7colondo

; Compressed form of IPv6 addresses
; Runs of zero-value octets are represented by '::'
;
; Examples:
; :: ==> 0:0:0:0:0:0:0:0
;
; 1:: ==> 1:0:0:0:0:0:0:0
; 2:2:: ==> 2:2:0:0:0:0:0:0
; 7:7:7:7:7:7:7:: ==> 7:7:7:7:7:7:7:0
;
; ::1 ==> 0:0:0:0:0:0:0:1
; ::2:2 ==> 0:0:0:0:0:0:2:2
; ::7:7:7:7:7:7:7 ==> 0:7:7:7:7:7:7:7
;
; E::1 ==> E:0:0:0:0:0:0:1
; E::2:2 ==> E:0:0:0:0:0:2:2
; E::6:6:6:6:6:6 ==> E:0:6:6:6:6:6:6
;
; E:E::1 ==> E:E:0:0:0:0:0:1
; E:E::2:2 ==> E:E:0:0:0:0:2:2
; E:E::5:5:5:5:5 ==> E:E:0:5:5:5:5:5
;
; E:E:E::1 ==> E:E:E:0:0:0:0:1
; E:E:E::2:2 ==> E:E:E:0:0:0:2:2
; E:E:E::4:4:4:4 ==> E:E:E:0:4:4:4:4
;
; E:E:E:E::1 ==> E:E:E:E:0:0:0:1
; E:E:E:E::2:2 ==> E:E:E:E:0:0:2:2
; E:E:E:E::3:3:3 ==> E:E:E:E:0:3:3:3
;
; E:E:E:E:E::1 ==> E:E:E:E:E:0:0:1
; E:E:E:E:E::2:2 ==> E:E:E:E:E:0:2:2
;
; E:E:E:E:E:E::1 ==> E:E:E:E:E:E:0:1
