Tell whether 10.1.2.0/16 is a network-id or an ip address?elaborate your answer?

10.1.2.0 is an IP address.

In the given statement, we can see that the first two octets are reserved for N/W id & the last two octets are valid host id.

But the host part is non-zero value. So, if the host part is non-zero value then it is an IP address.

Thanks.
