Subject: Access List

Hello,

Someone please help me understand the access-list provided below. The
task states that only the Hosts mentioned below have to be denied access
in the fewest lines of access list. Also no other hosts should be
blocked.

200.0.1.2

200.0.1.10

200.0.1.18

200.0.1.26

200.0.3.2

200.0.3.10

200.0.3.18

200.0.3.26

The solution listed only a single deny statement in ACL, the second
statement being permit ip any any

Access-list 1 deny 200.0.1.2 0.0.2.24

Please help me understand the math behind this solution.

Thanks,

Ajay
