What are the classes of Ip Address and its range?

Updated on August 29, 2008

Ip Address range

 

IP Adresse can be classified into five classes A, B, C, D and E. Each class consists of a contiguous subset of the overall IPv4 address range.

Range.

Class A 0-126

Class B 128-191

Class C 192-223

Class D 224-239 (Used for Mulicast)

Class E 240-255 (Used for Research and Education)

Private address range.

10.0.0.0 to 10.255.255.255

172.16.0.0 172.31.255.255

192.168.0.0 192.168.255.255

169.254.0.0 169.254.255.255(used as self assigned ip)

Thanks

      Hi Rajiv,

      127 can also be called as CLASS A but it cannot be assigned to any host. 127 is reserved for Loop back.
