IANA as of 19 March 2003. This document has been coordinated between the
IANA and a group of ccTLD managers and members of the ICANN Security and
Stability Advisory Committee. The intent of these changes is to streamline
the procedures for ordinary changes without compromising the minimally
necessary checks for the integrity of the top level of the domain name
system. This document is created by agreement between the ccTLD community
and the IANA and is to be updated and modified as experience warrants.
In this respect, this document has roughly the same status an IETF Proposed
Standard, viz it represents consensus after best effort to define the
process and will be reviewed after there is implementation experience.
This document specifically focuses on the procedure for handling requests
for changes in nameserver information in the root zone relating to ccTLDs.
gTLD changes have various minor differences based upon contractual relationships.
1. Receive request from TLD operator.
The ccTLD manager should fill in and send a complete a "Modification
Template" to <root-mgmt@iana.org>.
The template is available on the IANA web site. <http://www.iana.org/tld/cctld-template.txt>
2. Acknowledge request
Upon receipt of the request the IANA will reply to the person sending
the request plus the administrative and technical contacts of the ccTLD
(if different).
At this time the IANA will issue a ticket number in the format of:
ROOT-MGMT#YYYYMMDDNNN
The ticket will be initially be flagged OPEN-IANA.
OPEN refers to the unresolved status of the ticket. IANA refers to
the person who should take action.
Other status possibilities include. OPEN-TLD, OPEN-DOC and OPEN-IMPLEMENT-CHANGES
and CLOSED.
3. Initial template review
The IANA staff will review the template and, as necessary, revise it
to ensure that it precisely defines the change to the root zone being
requested and, ordinarily, to separate requests for other types of changes
to avoid delays in making the nameserver changes.
4. Verify request
The IANA staff will verify authorization/authenticity of the request
and obtain confirmation from the listed TLD administrative and technical
contacts that those contacts are aware of and in agreement with the
requested changes. A minimum authentication of an exchange of e-mails
with the e-mail addresses registered with the IANA is required. If the
address does not match or the IANA has reason to believe the person
using the e-mail address does not have current authority for the domain,
the IANA will investigate further.
The ticket status will change between OPEN-IANA and OPEN-TLD as e-mail
exchanges take place. In the event that an authentication fails, an
explanation of the failure will be sent to all involved in authentication
process and the ticket will be closed; at this point the ticket status
is set to CLOSED. If the requester believes that this is incorrect,
sending an e-mail with the ticket number will re-open the ticket. Refer
to the ticketing system information for exact details.[NOTE: Information
page being prepared.] In the event that the requested change affects
other TLDs, such as an IP address change of a common nameserver, IANA
will confirm with the machine owner that the change is indeed correct.
The IANA will inform all other affected TLDs before updating the glue
record in the root-zone.
5. Assess name server transition sequence to ensure
that it provides continuous name service for the TLD
In the event of a complete change of all servers the IANA may request
that some form of staggering of changes take place if it becomes apparent
that not doing so may cause the TLD to become temporarily unavailable
for portions of the network.
6. Verify new name server operational status/standards
compliance, using DNS queries and other tools such as ping and traceroute
The initial test will be in the form of a query to each server requesting
the SOA and NS resource records for the affected ccTLD. The expected
result would be that all machines give authoritative answers with the
same serial number and that they list an identical set of authoritative
servers. Differences will be considered as an error. If an error occurs
the IANA staff will attempt the tests at a later time and from a topologically
diverse machine to minimize the chance that the issue is one caused
by connectivity problems. The IANA will also check for necessary glue,
consistency between name server IP address and their respective glue
records, and consistency between NS records at parent and child.
Apparent lack of topological diversity, invalid e-mail addresses in
the SOA, and other items non-critical to the functioning of the zone
or the root servers and their ability to return answers will result
in a "Warning" or "Alert" being sent to the listed
technical and administrative contacts. Errors will result in the IANA
staff waiting for correction before implementing the zone changes. "Warnings"
or "Alerts" will result in a request for confirmation that
the ccTLD administrative and technical contacts are aware of and understand
the issues. With the exception of lack of topological diversity, improvements
in response to these "Warnings" generally do not require IANA
staff involvement as they take place outside the root zone. The IANA
staff will work with the technical and administrative contacts to assist
in addressing any technical issues.
7. Submit request for root-zone change to U.S. Department
of Commerce for approval
The IANA staff will submit the request for change to the DoC and the
root-zone editor. Any special instructions, such as special timing needs,
will be included with the request. At this point the status of the ticket
will be changed to "OPEN-DOC" and the requesters will be informed
of the status change.
8. The Department of Commerce approval will be sent
to the IANA and the root-zone editor
Once the IANA receives notification of the approval, the ticket status
is changed to OPEN-IMPLEMENT-CHANGES. The root-zone editor will implement
the approved changes according to any timing or other requirements in
the submitted request.
9. Monitor making of change to root zone
Upon making the necessary change in its registry database, the root-zone
editor will notify the IANA that the change has been made and say when
the change (i.e. zone serial number) is expected be propagated to the
root servers. The IANA will track the receipt or non-receipt of this
notice. Upon receiving it, the IANA will query the root servers to verify
that it has been properly propagated. Upon this verification, the ticket
will closed and the ccTLD technical and administrative contacts will
be sent a final e-mail ticket noting these facts and listing the current
status of the ccTLD. At this point the ticket status is CLOSED.
