What is IP address and its versions ?

IP address

This exclusive number is used by all information technology devices (printers, routers, modems, etc.) to identify and allow to communicate with each other on a computer network.

There is a standard of communication which is called an Internet Protocol (IP) standard.

IP addresses may either be assigned permanently for an Email server / Business server or a permanent home resident or temporarily, from a pool of available addresses (first come first serve) from your ISP.

Domain name system (DNS)

This allows IP address to be translated to a text format.

It is much easier for you to remember a web address name such as www.geniusprog.webs.com than it is to remember 172.168.1.1

Versions

IP version 4: Currently used by most network devices. IPv4 is limited to 4,294,967,296 addresses.

IP version 5: This is an experimental protocol for UNIX based systems.

IP version 6: The replacement for the aging IPv4. The estimated number of unique addresses for IPv6 is 2^128.

Dynamic and Static IP Address

Dynamic IP Address is an IP address that is not static and could change at any time.

This IP address is issued to you from a pool of IP addresses allocated by your ISP or DHCP Server.

Static IP Address is an IP address that is fixed and never changes.
