Short of using static IP addresses, is it possible to have a Cisco ASA use a DNS name rather than an IP address? For instance, if I want to limit a host in the DMZ to access only one particular web service, but that web service might be globally load balanced or using DynDNS or cloud, how can the ACL be expressed so that a fixed IP address isn't used and the admin doesn't have to keep opening and closing down IP addresses?
