My ip address is 188.8.131.52 and subnet mask: 255.255.252.0
20 points each.
a) That is a c-class ip, but shouldn't the mask be at least 255.255.255.0? It seemes that bits from network portion are borrowed. So is that a C-class address with a B-class subnet mask with 6 bits borrowed from host to network portion?
b) I calculated that the host range for that subnet is 184.108.40.206 - 220.127.116.11 where the first and the last address are unusable, is this correct?
