What is the IP Address ?
The IP host address, or more commonly just IP address, is used to
identify hosts connected to the Internet. IP stands for Internet
Protocol and refers to the Internet Layer of the overall network
architecture of the Internet. An IP address is a 32-bit quantity
interpreted as 4 8-bit numbers or octets. Each IP address uniquely
identifies the participating user network, the host on the network, and
the class of the user network.
An IP address is usually written in a dotted-decimal notation of the
form N1.N2.N3.N4, where each Ni is a decimal number between 0 and 255
decimal (00 through ff hexadecimal). Addresses are controlled and
assigned by the Internet Network Information Center at SRI
International. There are currently 5 defined classes of networks,
called A, B, C, D and E; classes A, B and C are available to users.
Each interface on a host system connected to the Internet must have its
own IP address.
