IP Number
Short for Internet
Protocol Number.
This is a unique
number consisting of 4 numbers, each between 0 and 255, separated by
periods (e.g. 201.0.57.254). Every computer that is connected to the
Internet has a unique IP number to identify it. The IP number is also
called an 'IP address' or 'dotted quad'.
The IP is an identifier for a computer or device on a TCP/IP network.
Networks using the TCP/IP protocol route messages based on the IP
address of the destination. The format of an IP address is a 32-bit
numeric address written as four numbers separated by periods. Each
number can be zero to 255. For example, 1.160.10.240 could be an IP
address.
You can try http://64.233.179.104/ on your browser and find out that
this is the IP address of Google.

evaluation you can find the ip
of your own
computer and find out more about each ip you enter. Check e.g. for the
country or the network (like AOL) of an ip address.
Within an isolated network, you can assign IP addresses at random as
long as each one is unique. However, connecting a private network to
the Internet requires using registered IP addresses (called Internet
addresses) to avoid duplicates.
The four numbers in an IP address are used in different ways to
identify a particular network and a host on that network. Four regional
Internet registries ARIN, RIPE NCC, LACNIC and APNIC assign Internet
addresses from the following three classes:
Class A - supports 16 million hosts on each of 126 networks Class B -
supports 65,000 hosts on each of 16,000 networks Class C - supports 254
hosts on each of 2 million networks
The number of unassigned Internet addresses is running out, so a new
classless scheme called CIDR is gradually replacing the system based on
classes A, B, and C and is tied to adoption of IPv6.
