Class A: IP address range from 0-127 in the first byte designed for very large companies.

Class B: IP address range from 128-191 in the first byte designed for medium-size companies.

Class C: IP address range from 192-223 in the first byte designed for small companies.

Class D: IP address range from 224-239 in the first byte reserved for multicast addressing. Not used in the public sector.

Class E: IP address range from 240-255 in the first byte reserved for scientific studies. Not used in the public sector.

The default mask is 255 means take same above value for calculation of AND operation.

C class Subnet Mask.

Default Mask 255.255.255.0.
So this answer:192.168.10.

How it is class network please explain?

Here The Last Mask Has Been Not Full on The Live the Desk than Its Associate With The C.

Now 192.168.10.51

Than Default Mask 255.255.255.0

Only Consider Empty Blogs than 192.168.10.0

192.168.10

192.168.10.51 is in Class C..so its default subnet mask is 255.255.255.0. so taking binary of both and apply AND operation
We get 192.168.10
