Glossary
DNS
Stands for Domain Name System and is a service that translates
domain names (such as
www.adaptec.com
) into IP addresses.
Domain names are alphabetic and easy to remember, but the
Internet is based on IP addresses (such as 192.168.8.1). Each time
you type in a domain name, a DNS service translates it into its
corresponding IP address. See
www.DynDns.org
for more
information.
