Hi Robert
Actually , wildcard bits means which bits router should verify , or ignore,
when analyse an incoming or ourgoing packet.
So , if you use
access-list 1 permit 172.16.0.0 0.0.255.255
, it means that all packets with source address 172.16.0.0 should be
permitted.
If you use access-list 1 permit 172.16.0.0 0.0.15.255 , it means that
router must verify the first's 4 bits, and ignore the last four bits of the
third octet.
Best regards
Henrique
