Border Router Question - Ingress Filtering

Border routers ACL In rule

Acl in
permit tcp any host ***.***.***.**6
permit tcp any host ***.***.***.**5
permit tcp any host ***.***.***.**4
permit tcp any host ***.***.***.**3
deny ip any any log

The firewall then filters on a port level.

My question is if they are denying all IPs other that what is specified in
the list is it necessary to then add the standard spoofing deny rules (ie
drop localhost, mulicast, RFC1918 addresses etc)? This will be taken care of
the deny ip any any rule would it not?
