I've been trying to crack prefix-list logic for past few days.
For instance to block all class B we would run:
ip prefix-list BLOCKb seq 1 deny 188.8.131.52/2 ge 17
so we matching 2 bits so thats 1100 0000 - which is 192 right ? so does that mean we matching addresses that start with 128-through-192 that have subnetmasks of 255.255.128.0 or greater ?
im greatly confused sorry if its obvious question ?
p.s edit did subnetting wrong
