Here is an example using and and or
here area three last octets in an ip address (163, 169, 174)
163
and 169
and 174
=======
160 <-- This is the network
163
or 169
or 174
=======
175 <-- This is the broadcast address
175
- 160
=======
15 <-- This is the subnet mask
Another great way to get the mask is to put the octets into binary.
line them up. Everything that doesn't match is a 1
Total up the binary 1s from your comparison. I don't know what logical
function this is but it seems to work
001
101
===
101 <-- this is 5 so your mask is 5
