Trying this post again...
Basically, the wildcard mask's 1 bits are the bits that will be ignored in
the ip address.
172.16.1.0 0.0.0.127
and
172.16.1.128 0.0.0.127
both refer to all addresses that share the same bit-structure for the first
25 bits...in the first case the 25th bit is a 1, in the second the 25th bit
is a zero. Between the two acl's that use these two ip/mask combinations,
you would be screening out the entire 172.16.1/24 anyway, so I would
recommend that you use an acl with: "172.16.1.0 0.0.0.255".
