Yes. If the address has 192.168.1.1, it will also match. If 192.168.7.1 in the list, it will match too. It depend on the AND result. Even you add 192.168.3.0 , after you key in, the access-list will still show as 192.168.1.0 for this wildcard

You would also match 192.168.1.1 with the wildcard mask that you provide right ? Can someome confirm this and share their experience about it ? Much appreciated Aung.
