Create an Access list to block the source address range 128.252.0.0 to
128.252.240.0
Solution 1:
access-list 1 deny 128.252.0.0 0.0.127.255 Blocks 128.252.0-127.0-255
access-list 1 deny 128.252.128.0 0.0.63.255 Blocks 128.252.128-191.0-255
access-list 1 deny 128.252.192.0 0.0.31.255 Blocks 128.252.192-223.0-255
access-list 1 deny 128.252.224.0 0.0.15.255 Blocks 128.252.224-239.0-255
access-list 1 permit any Allows all other traffic to
pass.
Solution 2:
access-list 1 permit 128.252.240.0 0.0.15.255 Permits 128.252.240-255.0-255
access-list 1 deny 128.252.0.0 0.0.255.255 Denies traffic from 128.252 that
is not permitted by the previous line
access-list 1 permit any
Notes:
Both Solutions work, but solution 2 has less lines and will result in less
processor utilization in most scenarios.
