What is an IP Address

The IP address is the digital label that is given to each device connected in a network.

The IP address is an unique number, which is used by machines to connect with each other, when transmitting an information via internet or local network. This address allows the machine, which transmit the information, to find the recipient machine accurately.

Types of IP addresses:

Static IP address – The address of a certain user does not change with each connection with internet and it stays static.
Dynamic IP address – With each new session of the user, the IP address changes, but it is similar to the previous IP address.
Local IP address – An IP address only for that local network.

IP Version 4

The IPv4 IP adresses consist of 32 bits, divided in 4 octets, each composed of 8 bits, which is theoretically 4 294 967 296 unique addresses. The IPv4 addresses usually are marked as а tetrad, separated by dots. For example we give you the following IPv4 address: The first three groups of numbers show the network and the last number – the address of the host in the network.

IP version 6

At IPv6 standard protocol for internet, the addresses are 128-bit, which theoretically means that there can be 18 445 618 199 572 250 625 unique addresses. The address of 6th version is written by eight 4-digits (16 bits) hexadecimal numbers, separated by colons. For example: 1160:0:0:0:0:600:0:518A.

The privileges of that protocol are the incredibly big capacity of the addresses, as well as the increased security by mandatory use of the IPsec standard.
