How does it work?
Through a Domain System Structure
- for example an Internet address (URL) like home.ubalt.edu tell us that this address: (a) belongs to the .edu -- education -- domain, (b) is part of a network called ubalt (of course the name of the UB network), and (c) that the machine (computer) name is home.
- there are many different (top) domains like gov, mil, com, net, etc, with new ones being added presently.
- each computer is assigned an IP number, like 18.104.22.168 -- the home.ubalt.edu IP number.
- a computer with a Fully Qualified Domain Name (FQDN) has a fixed IP number and name registered in the Internet.
