? Guys, Quick question that I'm trying to fully understand the logic. access-list 191 deny ip 150.20.66.0 0.0.0.127 150.21.21.128 0.0.0.127 access-list 191 deny ip 150.20.66.0 0.0.0.127 150.20.56.128 0.0.0.127 access-list 191 deny ip 150.20.66.129 0.0.0.126 150.20.87.0 0.0.0.254 //ACL above says the latter part of this subnet is denied access to all odd IPs in the 4th octet access-list 191 deny ip 150.20.66.129 0.0.0.126 150.20.80.0 0.0.0.254 //ACL above says the latter part of this subnet is denied access to all even IPs in the 4th octet ?Question: If you inverse 254, you come up with 1, so shouldn't that be matching odds? (we care about the last bit and if its a 1, it will match odd numbers) How would this match evens as well? (its the same as the ACL above it, no?)
