   - Date the name server was registered in the "created date"
     attribute.
   - ID of the entity that registered the name server in the "created
     by" attribute.
   - Date the name server was last updated in the "updated date"
     attribute.
   - ID of the entity that last updated the name server in the "updated
     by" attribute.

   Authorized User: The current registrar of a name server MAY use the
   STATUS command to view current domain name attributes.

   Examples

   The current registrar of a name server queries the name server:

   C:status<crlf>
   C:EntityName:NameServer<crlf>
   C:NameServer:ns1.registrarA.com<crlf>
   C:.<crlf>

4.3.10 TRANSFER

   This command allows a registrar to request transfer of domain name
   sponsorship from a second registrar and to approve or reject transfer
   requests initiated by other registrars. The request to transfer a
   domain name MUST contain the following data:

   - The "EntityName" parameter set to value "Domain".
   - Fully qualified second level domain name in the "DomainName"
     parameter.

   The identity of the requesting registrar is derived from the current
   active session. The identity of the current sponsoring registrar (the
   registrar who must approve or reject the transfer request) is known
   by the registry and does not need to be known by the requesting
   registrar in advance of issuing the transfer request.

   The System MUST notify the potential losing registrar when a domain
   transfer request has been received using an out-of-band transport
   mechanism such as electronic mail and/or transaction reporting. The
   losing registrar SHOULD then explicitly approve or reject the
   transfer. A request to approve or reject a transfer request MUST
   contain a single instance of the "Approve" parameter with a value of
   "Yes" to approve the transfer or a value of "No" to reject the
   transfer. A server implementation MAY provide a default approval or
   rejection action to be taken if the losing registrar does not
   explicitly approve or reject the transfer request within a fixed
   amount of time. The criteria used by registrars to approve or deny

   requested transfers are typically based on business policies that are
   beyond the scope of this document.

   Approval of a transfer by the current sponsoring registrar results in
   a change of sponsorship to the original requesting registrar.
   Approval attempts by any other registrar MUST result in explicit
   failure of the attempted approval.  Rejection of the transfer by the
   current sponsoring registrar results in an end to the transfer
   request with no change in sponsorship. Rejection attempts by any
   other registrar MUST result in explicit failure of the attempted
   rejection.

   Name servers MUST be implicitly transferred when their parent domain
   name is transferred.

   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.

   Examples

   A registrar requests transfer of a domain name from another
   registrar:

   C:transfer<crlf>
   C:EntityName:Domain<crlf>
   C:DomainName:example.com<crlf>
   C:.<crlf>
   S:200 Command completed successfully<crlf>
   S:.<crlf>

   The original registrar approves the transfer request:

   C:transfer<crlf>
   C:-Approve:Yes<crlf>
   C:EntityName:Domain<crlf>
   C:DomainName:example.com<crlf>
   C:.<crlf>
   S:200 Command completed successfully<crlf>
   S:.<crlf>

5. Response Codes

   RRP commands may return a variety of response codes to signify normal
   completion or error conditions. This section documents all of the
   defined RRP response codes.

5.1 Response Code Summary

   200 Command completed successfully
   This is the normal response for successful completion of most RRP
   commands.

   210 Domain name available
   This is the normal response for successful completion of an RRP CHECK
   command for a domain name that is not currently registered.

   211 Domain name not available
   This is the normal response for successful completion of an RRP CHECK
   command for a domain name that is currently registered.

   212 Name server available
   This is the normal response for successful completion of an RRP CHECK
   command for a name server that is not currently registered.

   213 Name server not available
   This is the normal response for successful completion of an RRP CHECK
   command for a name server that is currently registered.

   220 Command completed successfully. Server closing connection This is
   the normal response for successful completion of an RRP QUIT command.
   It may also be returned by other RRP commands if a transient
   situation is noted that requires closing the connection after
   successfully completing the RRP command.

   420 Command failed due to server error. Server closing connection A
   transient server error has caused RRP command failure and session
   termination. A new session must be established before continued
   processing can be attempted.

   421 Command failed due to server error. Client should try again A
   transient server error has caused RRP command failure. A subsequent
   retry may produce successful results.

   500 Invalid command name
   A client-specified RRP command name was not recognized as a valid RRP
   command name.

   501 Invalid command option
   A client-specified RRP command parameter was not recognized as a
   valid RRP command parameter.

   502 Invalid entity value
   The "value" of an entity name-value pair is invalid. Command blocks
   that require an "EntityName" parameter also require a value that
   specifies the entity name, and the provided value is invalid.

   503 Invalid attribute name
   A client-specified RRP command parameter was not recognized as a
   valid RRP command parameter.

   504 Missing required attribute
   A parameter required to execute the RRP command was not provided by
   the client. The command should be retried with all required
   parameters specified.

   505 Invalid attribute value syntax
   A supplied parameter value is syntactically incorrect. For example, a
   year value digit such as "5" may be required but the client provided
   a string of characters such as "five".

   506 Invalid option value
   A client-specified value for an RRP command parameter is out-of-
   bounds or otherwise not within acceptable System limits.

   507 Invalid command format
   The specified command does not resemble a well-formed RRP command.
   The command should be retried using the proper command structure and
   syntax.

   508 Missing required entity
   An entity required for command completion was not provided by the
   client. For example, the CHECK command requires specification of
   either a "Domain" entity or a "Nameserver" entity.

   509 Missing command option
   A command parameter that isn't really optional (such as the registrar
   ID in a SESSION command) was not provided by the client. The command
   should be retried with all needed parameters.

   520 Server closing connection. Client should try opening new
   connection; <why>
   A timeout event has been detected, and the client's session is being
   ended.  The System SHOULD define timeout periods to begin a client

   command, complete a client command, and for the duration of an open
   session. The reason for the timeout MUST be provided at the end of
   the response code string.

   521 Too many sessions open. Server closing connection
   A System-defined limit on the number of open connections has been
   exceeded, and it is impossible to establish a new session at the
   moment. It may be possible to establish a session by waiting for a
   few moments or by closing existing unused sessions.

   530 Authentication failed
   The client-supplied registrar identifier or password was not
   recognized by the System. A subsequent retry with valid values may
   produce successful results. Repeated authorization failures MAY
   result in termination of the TCP connection.

   531 Authorization failed
   Registrars may not view or alter data associated with either the
   registry or another registrar. This response code is typically
   returned when a registrar attempts to view or modify data belonging
   to either the registry or another registrar. A typical situation
   includes doing a STATUS command for a domain registered to another
   registrar.

   532 Domain names linked with name server
   The name server is hosting active domains. This error occurs when a
   registrar is trying to delete a server that is the name server for
   active domains.  The registry MUST not allow the registrar to delete
   this server. All of the domain names using this server MUST be
   modified to use a different name server before the name server can be
   deleted.

   533 Domain name has active name servers
   The domain name has active name servers. The registrar is trying to
   delete a domain name that is a parent domain of an active name
   server, i.e., a server that is hosting active domains. All of the
   name servers within the domain MUST be removed from service before
   the domain can be deleted.

   534 Domain name has not been flagged for transfer
   The registrar is trying to approve or reject a domain name transfer
   for a domain name that is not pending transfer.

   535 Restricted IP address
   IANA identifies certain IP address ranges that are not valid for
   normal use.  The registrar is trying to use an IP address that is in
   a restricted IP address range as identified by IANA.

   536 Domain already flagged for transfer
   The registrar tried to perform a transfer command for a domain name
   that is awaiting approval of an earlier transfer request.

   540 Attribute value is not unique
   A supplied attribute value is not unique. This occurs when the
   registrar is adding a domain name that already exists in the
   registry, a server that already exists in the registry, or an IP
   address that is already being used by another server in the registry.
   Another possibility occurs when performing domain modifications and
   the registrar is adding a server that is already in the list of
   servers for the domain name or setting a domain name to a status to
   which it is already set. The RRP STATUS command MAY be used to
   determine current domain name status before attempting to change the
   status. When modifying or adding a name server, the IP address of the
   name server might not be unique. The registry MUST not allow IP
   addresses to be used by more than one server.

   541 Invalid attribute value
   A supplied parameter value is invalid. Examples of invalid attribute
   values include an invalid IP address, an invalid domain name, an
   invalid server name, or an invalid renewal period.

   542 Invalid old value for an attribute
   A current attribute value to be modified is invalid. The registrar is
   trying to modify an attribute of a server or a domain name that does
   not exist in the registry.

   543 Final or implicit attribute cannot be updated
   The registrar is attempting to modify an attribute that is only
   modifiable by the registry. Registrars can not modify final or
   implicit attribute values.

   544 Entity on hold
   The attempted operation was rejected because the entity is on HOLD
   status. If the HOLD status was set by the registrar, the status can
   be changed using the MOD command and the requested command can be
   retried. If the HOLD status was set by the registry, the registrar
   must contact the registry to change the status before the command can
   be successful.

   545 Entity reference not found
   A required entity reference was not found. This occurs when the
   registrar tries to add a new name server and the parent domain of the
   name server does not exist in the registry. It also occurs when the
   user is trying to add a new name server to a domain name when the
   name server does not exist in the registry.

   546 Credit limit exceeded
   The registrar's credit limit has been exceeded. This is an
