    Just been having lots of fun reversing subnet masks into wildcard masks :blink Glad I got my subnetting down otherwise wildcard masks would've turned my brain inside out probably :p

    My question has nothing to do with wildcard masks whatsoever:

    Just been covering standard IP Access Lists and am now going over Extended IP Access lists, does the implicit deny rule apply to all types of access lists or just standard IP access lists?

    As I recall, the implicit deny is for both standard and extended.

    The implicit deny is present on all types of access lists. Often it can be a good idea to end the list with a deny all statement even though there is an implicit deny any.
