How Does the DNS Work?

The domain name system (DNS) will take care of

the translation of a domain name into an IP

address or vice versa.

For example, if a user were to type the URL

http://www.raritanval.edu, the DNS would

translate it into an equivalent IP address of

192.231.207.100.

International Domain Names

Domain names outside the United States are, for

example, as follows: Australia = au, India = in, Japan =

jp, China = cn, United Kingdom = uk, South Africa = za.

A domain for a university in Japan could be

ftp.meiji.ac.jp, for example, where the domain ac

stands for academic (college or university), analogous

to edu in the United States, to denote colleges and

universities.
