In the SAIR Linux and GNU networking exam there are usually questions about calcualting the subnet
address of a network given its net mask and the host address.
E.g. If a host has an IP address of 192.168.0.1 and a mask of 255.255.255.248 what is the network address of the subnet.
It takes binary maths to work this one out (rather simple if you have the time) but in the exam you just don't have time to go down to that level so I was wondering if anyone has come up with a trick using decimal numbers which would give the same answer or a prity good guess at one of the choices offered.
Cheers
