What counts as a domain?
Domain names are used for navigating the Internet with words rather than numbers, since words are easier to remember. For example, the OpenDNS System page is available at both system.opendns.com and 208.67.219.60. For Domain Tagging, a domain ends at the Top Level Domain (TLD): .com, .org, .co.uk and so on. Consider these two URLs: • en.wikipedia.org • en.wikipedia.org/wiki/Domain_name For Domain Tagging purposes, these are the same domain, en.wikipedia.org. See its domain detail page. For example, these two domains are unique. • mail.yahoo.com • search.yahoo.com Each of these domains has its own detail page.
