You can configure an access list to permit the ip's you want and there is an
implicit deny at the end of the access list. For example to permit 10.1.1.1
and deny everybody else: (make sure to apply the access list to an
interface)
access-list 1 permit 10.1.1.1 0.0.0.255

I can only assume this has somethign to do with a network of ip's assigned
by an isp to you as a customer? (Rajeev)

Maybe you do not wish to allow access through your firewall to those ip
addresses you don't have assigned to servers?

Or maybe you don't have a firewall and your servers are hanging on directly
behind your router? in which case, let me point you to
http://www.securityfocus.com

Or are you talking about an internal network that you would like to isolate
at the switch level which ip's can talk and which can not?  (If this is the
case, the you can't do it by ip, but you can do this my mac)  Would the goal
be to not allow any 'unknowns' on your local lan?

You specificity is somewhat lacking.
