Just want to check that I understand this correctly.
You can configure an inverse mask like this, 0.255.0.255, right?
My understanding is that the "255" represents all 1's so in that case is allowed.
So used in an access list for example:
permit 10.0.3.0 0.255.0.255 would allow anything from 10.0.3.0 through 10.254.0.254?
