I am looking at rolling out an application but setting an availability rule so that it will only run on workstations within a particular subnet for example such as only on workstations within 192.168.2.x subnet. I am aware of setting file and registry availability rules but I am unable to find any facility to do this on an IP address setting? I wanted to add an association to a root OU but just filter based on the IP range. Any help or advice would be great.
