Applying this list to the Serial 1 interface with the out option will stop any traffic from going out this interface. Extended ACLs can also be useful tools when trying to prevent malicious denial of service (DoS) attacks against your network. If, using network sniffing or some other means, the type of attack can be identified by what port it is attacking, it makes implementing extended ACLs considerably easier. At the end of this section on DoS attacksis a “catch-all” statement that makes this task a bit easier.
In addition when advertising about one network address into another network address, the routers will automatically summarize on the class network boundary, not the subnet field. This is a serious limitation to the flexibility of the network. Classless addressing remedies this issue by including the subnet masks with routing advertisements. In classless addressing, no default subnet mask is assumed. Another benefit of classless addressing is that it supports Variable Length Subnet Masking (VLSM).
