What is an IP address?

IP is an Internet protocol system. It was developed by Mr. Vint Cerf and Mr. Robert E. Kahn. in the 1980s.

IP (internet protocol) is the protocol by which is sent data from one computer to another device on the internet. Each computer on the internet has different IP address identify it from all other computers on the internet. An IP address is a numeric address and identifier for a computer or device on a network. Every device has and has an IP address for communication purposes.

The IP address consists of 2 parts. The first part is the network address and the second part is the host address.

There also two types of IP addresses the first one is the most common one is called IP version 4 (IPv4) and a second type is IP version 6 (IPv6).


Internet protocol version 4 (IPv4)

Internet protocol version 4 (IPv4) is the fourth version of the internet protocol (IP). This protocol most used today in data communications over different kinds of the network because it supports all devices.IPv4 invented in the 1970s, developed by the Internet Engineering Task Force (IETF).

Is IP version 6 4 is the current version (not for long) of IP addresses. 32-bit numeric address written as four numbers separated by periods (

Each group of numbers that are separated by period is called in architect. The number range in chartered is 0 to 255. This address has probably been generated by 1.5 billion so far.


Internet protocol version 6 (IPv6)

Internet protocol version 6 (IPv6) It is the most recent update version protocol of the internet. It provides location systems and traffic across the Internet to detect devices such as computers and mobiles.IPv6 invented in the 1990s, developed by the Internet Engineering Task Force (IETF).

The program that was developed for the first time on the Internet could not be understood as being so large in the World. They thought IP version 4 Which produced over 4 billion addresses would be enough, but they were wrong. The IP version 6 program has been developed for that.

IP version 6 is the next generation of IP addresses. The main difference between IP version 4 and IP version 6 is the link to the address. The IP version 4 address is its 32-bit numeric address. Where is IP version 6 is a 128-bit hexadecimal address? Hexadecimal uses both numbers and alphabets in the address.

1.IPv4 is a 32-bit address.

1.IPv6 IS 128-bit address.

2.IPv4 is the numbering address method.

2.IPv6 is the alphanumeric address method.

3.IPv4 binary bits are separate by dot(.)

3.IPv6 binary bits are separate by a colon(:).

4.IPv4 has a different 5 class of IP addresses.

Class A, Class B, Class C, Class D, Class E

4.IPv6 does not have any different types of IP addresses.

5.IPv4 has a limited number of IP addresses.

5.IPv6 has an unlimited number of IP addresses.

6. An example of an IPvs4 address is  357. 169.05 34.

6.Example of IPv6 address is  F3oo:89A9:ABCF:7987:AB84:G00T:9874:VWXY.

7.IPvp4 has 12 numbers of header filed.

7.IPv6 has 8 number of header filed.

8.IPv4 length of the header filed is 20-60.

8.IPv6 length of the header filed is 4o.

9.IPv4 has availableChechecksum field.

9.IPv6 has not available any Chechecksum field.

10.IPv4 pocket size is 576 bytes.

10.IPv6 pocket size is 1280 bytes.

11.IPv4 has an available optional filed.

11.IPv6 has not available an optional filed.

12.IPv4 is less secured.

12.IPv6 is more than required compared to IPv4.

13.IP sec support is optional in IPv4.

13.IP sec support is required in IPv6.

14.IPv4 uses both multicast and broadcast m passage transformation scheme.

14.IPv6 doesn’t use broadcast uses a different type of multicast massage transformation scheme.

15.IPv4 supports VLSM (Virtual Length Subnet Mask).

15.IPv6 doesn’t support VLSM.



IPv4 and IPV6are applied to identify a device connected to a network. Networks like IPv4 and IPv6 are cannot communicate with each other, but they can be together on the same national network. This is called a dual-stack.
