Internet-Draft VeriSign RRP v2.0.0 June 2002
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.
2. Protocol Updates
This specification describes several modifications to RFC 2832 [2]:
two new response codes have been added, domain TRANSFER command
processing is updated to allow a client to cancel a requested domain
transfer, and support for IPv6 name server addresses is added.
2.1 Response Codes
Section 5.1 of RFC 2832 [2] is updated to include two additional
error response codes.
510 Invalid encoding
The value of a domain name or name server entity contains an 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.
Section 5.2 of RFC 2832 [2] is updated to include the addition of
response code 510 to the possible error values 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.

Internet-Draft VeriSign RRP v2.0.0 June 2002
Section 5.2 of RFC 2832 [2] is updated to include the addition of
response code 557 to the possible error values 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] is updated to include an additional
TRANSFER command processing option.
Old 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 or reject a requested transfer. The registry
MAY implicitly approve or reject requested transfers after a fixed
amount of time.
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:.<crlf>
S:200 Command completed successfully<crlf>
S:.<crlf>
2.3 IPv6 Name Server Addresses
Section 7 of RFC 2832 [2] is updated to include support for name
servers using IPv6 addresses. IPv6 addressing architecture is
described in RFC 2373 [3]. This ABNF 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
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
