The list does not constitute an endorsement of any particular registrar. This is being provided for informational purposes to track the adoption of DNSSEC and provide information for users who may have questions about which registrars support DNSSEC.

If your registrar currently accepts DS records, please send an email with subject "DNSSEC REGISTRAR UPDATE" and body containing company name, country location, URL, what TLDs you accept DS records for, whether your Web interface supports DS records, whether you provide DNSSEC signing services to and the Security team will add your registrar to this DNSSEC page.

See ISOC's comprehensive DNSSEC registrar site for HowTos and more information.

Is DNSSEC supported at my Top Level Domain?

A list of Top Level Domains (TLDs) that support DNSSEC are at the right starting with the TLD most recently deploying DNSSEC. This means these TLDs are technically capable of supporting DNSSEC. If you see a TLD listed here that isn't supported by the registrars above it could mean there is no automated way to enter DS records yet, you may need to do it manually by emailing in your DS records to a support contact.

How do I know if the site I am connecting to supports DNSSEC?

While we don't endorse or vouch for any of the tools or applications below, here is a short list of DNSSEC enabled browser plugins:

Name Browser(s) Notes
DNSSEC Validator FireFox
DNSSEC Validator Chrome

How do I debug problems?

  • DNSViz A DNS Visualization Tool - Sandia National Labs
  • DNS Check The Internet Infrastructure Foundation
  • DNSSEC Analyzer DNSSEC Debugging Tool - Verisign Labs

Domain Name System
Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as"""" is not an IDN."
