  • List of these addresses v4
  • special addresses
  • IP address country format

About IPv6:

    • format address

About IPv4:

Recently, it’s a commonly used.

Have 32 bit and split 4 octets(one octet is 8 bit), digits separated by dot(.)

There have 5 classes of available in IP ranges: Class A, Class B, Class C, Class D, Class E. But, Classes A,B,C are commonly used.

The lists of these addresses below:

Class

Bit header

Address Range

Supported

Class A

0…..

1.0.0.1      -> 126.255.255.254

16 million hosts on each of 127 networks

Class B

10…

128.1.0.1 -> 191.255.255.254

65, 000 hosts on each of 16, 000 networks

Class C

110..

192.0.1.1 -> 223.255.255.254

254 hosts on each of 2 million networks

Class D

1110…

224.0.0.0 -> 239.255.255.255

Reserved by multicast

Class E

11110..

240.0.0.0 -> 254.255.255.254

Reserved by future

 

Special addresses:

Address 255.255.255.255 is broadcast to all host on local network

 

IP address country format:

About IPv6:

It will be used for future

Have 128 bit. Give us more than 340x 1036 (340 million of billion of billion)

There have 8 octets in IP ranges and digits separated by colon(:)

IPv6 addresses divided into two parts : 64 bit network prefix, 64 bit interface identifier.

For example :

 2001:db8:1f70::999:de8:7648:6e8

 

Address format:

IPv6 original:

fe80:0000:0000:0000:0202:b3ff:fe1e:8329 

Leading zero can be skipped.

fe80:0:0:0:202:b3ff:fe1e:8329

 

A occurrence of Groups of zero  can be replaced by double colons.

fe80::202:b3ff:fe1e:8329

 

Environment of dual stack hosts that support both v4 and v6:

Mapped IPv6 :  ::ffff:c000:280  is usually written as  ::ffff:192.0.2.128

Represent IPv4 : 192.0.2.128
