So for 192.168.1.0/24 you'd have:

192.168.1.0 - Network address (NOT usable for hosts)
192.168.1.1 through 192.168.1.254 - Free IPs (Usable for hosts)
192.168.1.255 - Broadcast address (NOT usable for hosts)

And for /25 sub-nets (and all others besides) it'd be the same: the first address in the range and the last address in the range are not usable for hosts.

Thank you Drysdalk . i believe i didn't understood properly what a single ip address means. From your above explanation . for e.g.

Code:

192.168.1.1 through 192.168.1.254 - Free IPs (Usable for hosts)

Does all those ip are list of single ip address. i believe list of hosts in ip class means list of single ip address. Does my public ip address as mentioned

Code:

46.126.40.51

means one of hosts from class A public ip address .
