Easiest way would be to create 2 address lists; one for those that are blocked and one for those that are not.

Simply add the IPs to the each respective list.
Create a FW rule that allows access to those sites in question; under the “advanced tab” select the appropriate address list.
Create a FW rule that denies access to those sites in question; under the “advanced tab” select the appropriate address list.
