OK I get the AND and XOR stages in calculating the wildcard, taking it a
step further say I had to work out a single line for:

192.168.10.0
192.168.11.0
192.168.12.0
192.168.13.0
192.168.14.0
192.168.15.0

I would use 192.168.8.0 0.0.7.0, what if I just wanted to match the even
numbered addresses?

Would I have to deny 192.168.8.0 0.0.1.0 then permit 192.168.8.0
0.0.7.0?
(theory being that any bit in the 1 position makes the number odd -
right?), therefore all you are left with is the even numbered networks.

Thanks

Andy
