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.
