How do I register a domain in the .GOV, .US, .CA or other top-level domains?

.GOV domain

• If the organization is a US Federal Government civilian agency:
  • World Wide Web: http://www.registration.fed.gov
  • Email: registration@fed.gov
• If the organization is a US military agency:
  • World Wide Web: http://www.nic.mil
  • Email:hostmaster@nic.mil

The .US domain, for local, regional, or state agencies, is administered by The US Domain Registry at the Information Sciences Institute of the University of Southern California (USC-ISI) in Marina del Rey, California, under the Internet Assigned Numbers Authority (IANA). They have an excellent WWW resource at the URL: http://www.isi.edu:80/in-notes/usdnr/

The .CA domain is administered by the CA Domain Committee and the University of British Columbia. CA*net Networking Inc. maintains at their WWW site, information regarding the Canadian IP Address Registry and the Canadian Domain Name Registry as a public service at the URL: http://www.canet.ca/canet/index.html

Other registries: Refer to the list of other registries or use the Whois database at rs.internic.net to determine which entity is the domain authority for a country by typing the country's ISO 3166 two-letter country code (listed in http://www.iana.org/in-notes/iana/assignments/country-codes) followed by the suffix -DOM. For example:

 Whois: US-DOM
 United States of America top-level domain (US-DOM)
    Internet Assigned Numbers Authority (IANA)
    c/o
    University of Southern California
    Information Sciences Institute
