Name that identifies one or
more
IP addresses. For
example, the domain name
microsoft.com represents
about a dozen IP addresses.
Domain names are used in
URLs to identify
particular
Web pages. For example,
in the URL
http://www.pcwebopedia.com/index.html,
the domain name is
pcwebopedia.com.
Every
domain
name has a
suffix that indicates which
top level domain (TLD)
it belongs to. There are
only a limited number of
such domains. For example:
Because the Internet is
based on IP addresses, not
domain names, every
Web server requires a
Domain Name System (DNS)
server to
translate domain names into
IP addresses.
See our list of
Domain Extensions and
the countries they coincide
with in the
Quick Reference section
of Webopedia.
