    Network classes are dead, killed in 1993, by RFCs 1517, 1518, and 1519, which define CIDR (_Classless_ Inter-Domain Routing). Modern networking does not use network classes. Please let them rest in peace. See the excellent answer to [this question](https://networkengineering.stackexchange.com/q/7106/8499) for how to do what you ask. – Ron Maupin Nov 21 '17 at 21:10

Use ipcalc on Linux:

# ipcalc 182.44.82.16 255.255.255.192
Address:   182.44.82.16         10110110.00101100.01010010.00 010000
Netmask:   255.255.255.192 = 26 11111111.11111111.11111111.11 000000
