Just try to commit this to memory: Zeroes in the mask means the address
must match in that bit position. The "ones" can be thought of as "don't
care" bit positions. This is why
a host of 0.0.0.0 255.255.255.255 is the long way of specifying any host in
the extended access-list.
Hope something clicked.
