Is this a valid example? and is my thinking correct?
73.19.22.14/17
Code:
11111111.11111111.1/1111111.11111111
network host
So 17 bits for network ID
Here's the break down for the value of each bit
Code:
128 64 32 16 8 4 2 1
So 15 bits for host ID which gives us
127 + 256 = 383 ips - 2 which leaves 381 available IP
I reserve 2 IPs for the network ID and broadcast IP.
Code:
Network ID: 73.19.22.14
IP Range: 73.19.22.15 - 73.19.22.255
73.19.23.0 - 73.19.23.143
Broadcast IP: 73.19.23.144
Now on my IP Range, 73.19.23.0 and 73.19.22.255, can they be an IP or should it have been
Code:
Network ID: 73.19.22.14
IP Range: 73.19.22.15 - 73.19.22.254
73.19.23.1 - 73.19.23.145
Broadcast IP: 73.19.23.146
