Cctld zone file access

The query by which the transmission of a zone file from a name server is requested is commonly known as "AXFR", after the corresponding DNS query type. See RFC , section 3. For some time, name servers have made AXFR access available to everyone who'd ask.

For the rather common BIND name server, access to zone files can be controlled by using the xfrnets directive introduced in bind Requests for changes to nameservice for other TLDs must result in delegation to nameservers on at least five different network segments.

Delegations of a TLD to more than thirteen nameservers are not supported. Prior to submitting the request, nameservice should be set up at all the nameservers to which delegation is to be made. Lame delegations i. The IANA must have zone file access. Except where other arrangements are made such as for TLDs with large zones , this means that zone file transfers must be enabled at all nameservers for transfers to at least Sponsoring Organization name and postal address.

Administrative Contact name, postal address, e-mail address, telephone number, and facsimile number. Technical Contact name, postal address, e-mail address, telephone number, and facsimile number. Date of creation of Delegated ccTLD. Date of last update to information for Delegated ccTLD. URL for registration services. The above list of elements required to be published pertains only to data in the Authoritative-Root Database. To the extent that data is not in the Authoritative-Root Database because it has not been supplied by the Sponsoring Organization or for other reasons, it need not be published.

IPv6 addresses are not currently supported in the root zone. The published data will be updated from the Authoritative-Root Database at least three times per week. Requests for changes in TLD contact data are to be submitted by e-mail to root-mgmt iana.

Requests for changes to TLD contact data must include all applicable elements of data requested in items of the template. All information submitted must be accurate. Contact change requests are subject to verification of authenticity and authorization.

Except where a contract between ICANN and the TLD delegee, sponsor, or operator expressly states to the contrary, the IANA shall be entitled to rely on authorization of either the administrative or technical contact as constituting a request for a contact change by the TLD delegee, sponsor, or operator, except that any change of the identity of the Sponsoring Organization, administrative contact, or technical contact must comply with notice requirements stated in the agreement.

To the extent they are not specifically dealt with in the Governmental Communication, the Sponsoring Organization shall abide by policies established under Section 5 of the Agreement on the following topics:. Attachment F Limitations on Contribution Requirements. Fixed Annual Contribution. The fixed annual contribution shall be an amount established by the ICANN Board of Directors, in conformity with the ICANN bylaws and articles of incorporation, not to exceed the maximum fixed annual contribution described in item 4 below.

Variable Annual Contribution. The variable annual contribution shall be in an amount calculated according to a formula and method established from time to time by the ICANN Board of Directors, in conformity with the ICANN bylaws and articles of incorporation.

The formula and method shall allocate the total of all variable annual fees and contributions among all TLDs sponsored or operated under a sponsorship or registry agreement with ICANN whether the fee or contribution is collected at the registry or registrar level based on the relative size of the registries for those TLDs.

It shall be permissible for the formula and method so established a to measure the size of a TLD's registry by the number of names under administration within the TLD by the registry's operator, b to deem the number of domain names under administration within the Registry TLD to be the number of Registered Names, c to provide for a deduction in computing a sponsor's or operator's variable annual fee or contribution of some or all of that sponsor's or operator's fixed annual component.

It shall also be permissible for the formula and method to consider accreditation fees collected from registrars as a credit applied to the variable annual fee or contribution for the TLD to which the fees pertain. Groups of registries for two or more TLDs whether or not under agreement may, with the agreement of their sponsors or operators and ICANN, agree to allocate the variable fees and contributions collected from them in a manner not based on the relative size of the registries within the group, provided that the combined variable fees and contributions collected for all TLDs within the group is based on the combined size of the registries in the group.

Payment Schedule. The Sponsoring Organization shall pay the fixed and variable annual contributions in one or more installments, as established for each year by ICANN. These payments shall be made in a timely manner throughout the Term of this Agreement and notwithstanding the pendency of any dispute between the Sponsoring Organization and ICANN. Contribution Caps. The sum of the fixed and variable annual fees contributions due to be paid in any year ending on any 30 June during or within one year after the Term of this Agreement by all TLD sponsors and registry operators having registry or sponsorship agreements with ICANN shall not exceed the total annual fee cap described in the following sentence.

There must be Internet Protocol IP connectivity to the nameservers and electronic mail connectivity to the entire management, staff, and contacts of the Sponsoring Organization. We have seen nothing to indicate that a publicly available zone file would have any impact on the volume of spam.. If you have reasons not to reveal a domain name prior to actively using it, like when launching a campaign or a new brand, you should refrain from delegating it.

As long as there is no delegation, the domain will not show up in the the zone file for. Ask your registrar for help if you have questions about this. In order to use a domain for anything, it must be published in the zone file.

If you do not want it included, you can opt to not delegate the domain. Note that some information on a registered domain can still be obtained through Whois, but only if you already know the exact domain name.

It is not possible to query for a list. The IP addresses in zone files do not identify any individuals. They are infrastructure addresses and therefore to be viewed as public information.

These IP addresses may, for example, be necessary to reach the authoritative name servers for a domain, in which case they are tied to the DNS operator. Apart from name servers, the addresses could belong to web servers, routers, and other equipment that makes up the infrastructure of the Internet, and likewise, they are tied to an operator.

As such, they cannot be considered secret or sensitive information, and cannot be used to identify a user. DNS provides technical information about the domain, while Whois provides limited information about the domain owner. The zone file that we publish is identical to the one installed on our name servers. We update the zone file every hour, which means you always have access to the most recent zone data.
