Hi Team:

This may be a very basic question, but I am confused about which access-list
is right

We know that the private address range is 172.16.0.0 172.31.0.0 /12

So if we have to filter RFC 1918 addresses, which access-list is right

access-list 10 deny 172.16.0.0 0.15.255.255

or

access-list 10 deny 172.16.0.0 0.31.255.255

Your input will be highly appreciated.

Thanks
