If pic is not clear: Data:
Dept1 (with X link) has 287 hosts. Dept2 (with Y link) has 510 hosts. Dept3 (with Z link) has 254 hosts.
Qstn: If above network uses class C network 192.203.16.0 then find DBA for dept Y. (Assume all are in the same network.)
How can this be done? Dept2 has 510 hosts , so 9 bits needed. But as it is a Class C IP, can you get my confusion? Kindly help me clarify it. How to even proceed for this qstn?
