Evaluating Resources: Home

Domain Authority

What does the domain reveal about a website's true purpose? The domain is the primary web address for a site, usually composed of the last portion of the address, i.e. nasa.gov or nineplanets.org.

The first three sites below are all "IRS" sites, but only one actually represents the government agency. 

Tip: WHOIS behind that domain? identifies the registered owner of a website.

.gov Government agency: www.irs.gov
.net Network provider: www.irs.net
.com Commercial site: www.irs.com
.edu Higher education: www2.indwes.edu
.mil Military site: www.navy.mil
.org Organization, may be charitable, religious or a lobbying group: www.unicef.org
