The
Internet Infrastructure
The Internet
is set up in terms of domains and networks.
Domains
A domain is
a reference to a computer connected to the Internet. Domain names
contain the actual name of the computers, a domain prefix and sometimes
a country code. The domain prefix shows the type of domain and the
country code represents the country the domain belongs to. Some
(not all) common domain prefixes are as follows :
- .com - Commercial
organizations, companies, people
- .us - USA
based companies, organizations or people
- .edu - Educational
institutes
- .gov - Government
owned institutes
- .mil - Military
domains
- .net - Gateways
and other networks
- .org - Private
organizations
- .int - International
domains
- .to - Referral
& redirection
Networks
In very simple
words a network is a group of domains usually held by one owner(though
not necessary). A network contains all the required administrative
tools for the administration of the domains in the network.
