IP Address

The IP address is a numeric value of 32 bits in OCTATE configuration separated by dots (Periods). There are 4 blocks. Each block contains 8 bit of numeric value. The range of IP address is defined by the IANA (Internet Assigned Network Authority) from 1.0.0.0 to 255.255.255.255. Among these range the IP address is classified in 5 classes. That are class A, B, C, D and E. Among these 5 classes of IP address, we can use only the IP of class A, B, C. The IP of class D and E are reserved IP address. Class D is reserved for multitasking and broadcasting purpose. And class E is reserved for future use in scientific research.

The range of IP are defined as:

Class ‘A’         1.0.0.0                  to      127.255.255.255

Class ‘B’         128.0.0.0    to      191.255.255.255

Class ‘C’         192.0.0.0    to      223.255.255.255

Class ‘D’         224.0.0.0    to      239.255.255.255

Class ‘E’         240.0.0.0    to      255.255.255.255

Note: 1)  From the IP of class ‘A’, the range 127.0.0.0 is reserved for testing network.

     2)  From the class ‘B’, the IP range of 169.254.0.0 is reserved for Automatic IP address.
