A Domain Name system (DNS) server is like an index of IP addresses and Web
addresses. If you type a Web address into you browser, a DNS server will find
that name in its index and find the matching IP address. Most ISPs provide a
DNS server for speed and convenience. Since many Service Providers connect
to the Internet with dynamic IP settings, it is likely that the DNS server IP
addresses are also provided dynamically. However, if there is a DNS server that
you would rather use, you need to specify the IP address below.
