Question { 31624 }

You have the following Network ID: 192.115.103.64/27. What
is the IP range for your network?

Answer

It ranges from 192.115.103.64 - 192.115.103.96

But the usable address are from 192.115.103.65 to
192.115.103.94

192.115.103.64/27

192.115.103.64 network ip address
192.115.103.65 first valid ip address
192.115.103.94 last valid ip address
192.115.103.95 broadcast ip address
192.115.103.96 next hop

32 ip address we will get

1-30 usable ip address we can assign to hosts

32-2=30

because one ip address reserved for network
another ip address reserved for broadcast

192.115.103.95 - it is the broadcast address
192.115.103.96 - will be the ip address of next range

we can use 30 hostes in this network
