DNS
A Domain Name Server (DNS) is an index of IP addresses and web
addresses. If you type a web address into your browser, such as
www.smc.com, a DNS server will find that name in its index and find the
matching IP address: xxx.xxx.xxx.xxx. Most ISPs provide a DNS server
for speed and convenience. Since your Service Provider may connect to
the Internet with dynamic IP settings, it is likely that the DNS server IP’s
are also provided dynamically. However, if there is a DNS server that you
would rather use, you need to specify the IP address here.
