There’s no mystery in the IP address!

The Computer is a very complicated device we use for our every day comfort and the importance of some of its numerical aspects is sometimes neglected.

For example: a different number is given to each computer when its user goes online or when it is part of a network. This number is the IP address and knowing about it is like knowing where you live…

What’s my IP and what do its numbers stand for?

IP stands for Internet Protocol and the address is formed from 4 numbers separated by periods.

The IP address format is a 32 bit numeric one and each number can be from 0 to 255.

The IP address consists of two parts: first one represent the network number and it is similar for more than one user (like the number of a street) and second represents the host name which is different for each user (like the house number).

To increase the number of available IP addresses within big networks with a lot of users or small networks with few hosts, the address is divided into 4 classes (A, B, C, and D)

Having an IP address it’s like having a last name in a network. To identify a computer in a network (LAN-local area network, WAN-wide area network or on the Internet) it has to have an IP address.

This number is similar to a phone number or to a zip code. It is unique and without it the device or computer can not be used in a network area.

Within an isolated network the computers can be assigned different random IP addresses, but if a private network needs to be connected to the Internet the IP has to be registered so that its uniqueness is verified.
