Where r = h * 256 + i

Class C

For Class C IP addresses, the h and i fields will always consist of

4 bits, each taken from the REST field of the Internet address. The mapping

follows the same rules as for Class A.

Example

For h < 64:

DDN X.25 Physical

Address Format

ZZZZ 1 RRRRR ZZ (SS)

X.121 Address

0000 1 19202 00 00

IP Address

192.33.50.19

Format

n.n.n.h.i

n.n.n. .0001 .0011

subnet 1

submask 3

DDN X.25 Physical

Address Format

ZZZZ F III HH ZZ (SS)

X.121 Address

0000 0 003 01 00 00

Note:

The mapping of X.121 address for Class C networks for h > 64 is not

applicable because the h field can never exceed 15.
