Whois Specifications

(1 December 2012)

Public Whois Specification

Registry Operator will operate a WHOIS service available via port 43 in accordance with RFC 3912, and a web-based Directory Service providing free public query-based access to at least the following elements in the following format.

Registry Operator commits to participating in and supporting the work in the IETF to produce a Domain Name Registration Data Access Protocol [SAC 051]. Registry Operator shall implement the standard no later than 135 days after it is requested by ICANN if: 1) the IETF produces a standard (i.e., it is published, at least, as a Proposed Standard RFC as specified in RFC 2026); and 2) its implementation is commercially reasonable in the context of the overall operation of the registry.

Registry Operator's Whois service is the authoritative Whois service for all second-level Internet domain names registered in the .com top-level domain and for all hosts registered using these names. This service is available to anyone. It is available via port 43 access and via links at the Registry Operator's web site. It is updated daily. Registry Operator offers public IPv6 transport for its Whois.

To use Registry Whois via port 43 enter the applicable parameter on the command line as illustrated below:

  • For a domain name: whois "domain verisign.com"
  • For a registrar name: whois "registrar Go Daddy Software, Inc."
  • For a nameserver: whois "DNS3.REGISTER.COM" or whois "nameserver 216.21.234.72"

By default, Whois performs a very broad search, looking in all record types for matches to your query in these fields: domain name, nameserver name, nameserver IP address, and registrar names. Use keywords to narrow the search (for example, 'domain root'). Specify only part of the search string to perform a "partial" search on domain. Every domain starting with the string will be found. A trailing dot (or dots) after your text or the partial keyword indicates a partial search. For example, entering 'mack.' will find "Mack", "Mackall", "Mackay", and so on.
