[cbs_my]

100.20.1.0 with subnet mass 255.255.255.252....

How many subnet does it has?

How many IP address does it has?

what is the IP broadcast address?

[mhussein]

This is a subnet of class A 100.0.0.0 255.0.0.0

It does not have any subnets, and it can not be further subnet'd

it has 2 usable ip addresses:

100.20.1.1

100.20.1.2

The broadcast address is 100.20.1.3

Usually subnets with mask 255.255.255.252 are used for point-to-point serial interfaces. The subnet can also be represented as 100.20.1.0/30, where 30 refers to the number of bits (1's) in the subnet mask.
