Here’s a list of some common top-level domain names.
.edu - educational site (usually a university or college)
.com - commercial business site
.gov - U.S. government/non-military site
.mil - U.S. military sites or agencies
.net - networks, Internet service providers, organizations
.org - non-profit organizations and others
Because the Internet was created in the United States, “US” was not originally assigned to U.S. domain names; however, it’s used to designate American state and local government hosts, including many public schools, and commercial entities, e.g., well.sf.ca.us. The domain .ca represents Canada, unless it’s followed by .us, in which case it represents California.
Domain Codes State
.ca.us California
.nv.us Nevada
.tx.us Texas
Other countries have their own two letter codes as the top level of their domain names — although many non-US sites use other top-level domains (such as .com):
Domain Codes Country
.ca Canada
.de Germany
.dk Denmark
.jp Japan
.il Israel
.uk United Kingdom
.za South Africa
To limit results to a single site or domain, specify the site name (e.g.,
www.googleguide.com
or googleguide.com
) or a top-level domain name (e.g., .com
or .edu
) in Google’s domain selector.Taken from: www.googleguide.com
