TCP/IP CHARACTERISTICS – IP (INTERNET PROTOCOL ADDRESS) – An IP Address Is A Numeric Address. It’s An Identifier For A Computer Or Device On A Network. Every Device Has To Have An IP Address For Communication Purposes.

The IP Address Consists Of Two Parts:-

  • First Part Is The Network Address
  • Second Part Is The Host Address


There Are Two Different Types Of IP Addresses

  • IPv4
  • IPv6

The First One Is The Most Common One, Its Called IP version 4

The Second Type Is Called IP Version 6.



IPv4 Is The Current Version Of The IP Addresses.

It Is A 32 Bit Numeric Address Written As Four Numbers Separated By Periods.

69 . 92 . 232 . 11


Each Group Of Numbers That Are Separated By Periods Are Called Octets.

The Number Range In Each Octet Is 0-255.

This Address Version Can Produce Over 4 Billion (4,294,967,296) Unique Addresses.




When Internet Was First Developed, Programmers Didn’t Realize How Big It Becomes.

They Thought That IPv4 Which Produce Over 4 Billion Addresses Would Be Enough.

But They Were Wrong.

IPv6 Is The Next Generation Of IP Addresses.


The Main Difference Between IPv4 And IPv6 Is The Length Of An Network Address.

A IPv4 Address Is 32-Bit Numeric Address.

Where As IPv6 Is A 128-Bit Hexadecimal Address.

Hexadecimal Uses Both Number And Alphabets In The Address.


So With This Type Of Address IPv6 Can Produce An Unbelievable 340 Undecillion Addresses.

i.e 340 with Thirty Six Zero’s After It (340,282,366,920,938,463,463,374,607,431,768,211,456

So As You Might Have Guessed, IPv6 Is More Than Enough For The Perceivable Future.
