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.
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.
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.

PROBLEMThe RRP protocol (RFC 2832) lacked support for IPv6 and had incomplete handling of transfer cancellations, and domains with non-ASCII names needed better encoding validation.
MECHANISMRFC 3632 adds two new response codes (510 for invalid encoding, 557 for locked nameservers), allows registrars to cancel pending transfer requests, and introduces support for IPv6 name server addresses.
WHAT IT ENABLESThese updates bring RRP to version 2.0.0, enabling registrars to manage internationalized domains and giving them finer control over transfer requests while supporting the growing IPv6 Internet.
§1Introduction
RRP (Registry Registrar Protocol) is how domain registrars communicate with the registry that manages a top-level domain (TLD). RFC 3632 updates version 1.1.0, originally published as RFC 2832, to version 2.0.0 and adds capabilities that were missing.
The update enables internationalized domain name validation, gives registrars control over pending transfers, and adds IPv6 support to address evolving needs in the DNS ecosystem.
RRP is the rule book shops use when talking to the name database about web names they are managing for customers. This update adds three new rules to that book.
§2Response Codes and Validation
RFC 3632 introduces two new response codes. 510 (Invalid encoding) tells a registrar that a domain name or nameserver name contains invalid ASCII compatible encoding (the standard way to represent non-ASCII domain and host names). This error is checked when adding an internationalized domain or nameserver, or when changing a nameserver name to an internationalized one.
557 (Name server locked) indicates that a nameserver is hosting a TLD in the root zone of DNS and cannot be modified or deleted without approval from IANA and the U.S. Department of Commerce. This protection ensures root infrastructure stability.
Two new error messages tell the shop: "that name is written wrong" and "that server can't be changed without permission from the very top people."
§3Transfer Request Cancellation
Under RFC 2832, once a registrar requested a domain transfer, the request could only be approved or rejected by the sponsoring registrar or implicitly approved after a fixed time. RFC 3632 adds a new capability: the requesting registrar may now cancel a pending transfer request using an updated TRANSFER command with -Approve:No.
The cancellation must be sent before the sponsoring registrar explicitly approves or rejects the request, or before the registry implicitly approves or rejects it. This gives registrars more operational flexibility.
If you ask to move a web name to a different shop, you can now say "never mind" before anyone says yes or no.
§4IPv6 Name Server Addresses
RFC 2832 was written before IPv6 became common. RFC 3632 adds grammar to the RRP protocol to support IPv6 address notation alongside the existing IPv4 support.
The RFC includes ABNF (Augmented Backus-Naur Form) grammar for both standard IPv6 notation (eight groups of 1 to 4 hex digits separated by colons, such as 10AA:0:0:00:8:800:200C:417A) and compressed notation (using :: to represent runs of zeros). This lets registrars specify nameservers using modern addressing.
The update teaches the system how to write down IPv6 addresses (the newer, longer type of internet address) so nameservers can use them.
