I am trying to dynamically group PCs based on the first 2 octets of the IP address of the machine. When I create the group in SDP and select "IP" + "begins with" the system will only show PCs if I use the first octet ONLY. When I add the second octet no machines are displayed (Yes there are machines with that IP range in the system) e.g. 10.5.

Is this how the  system  is intended work? Our machines are grouped per floor by IP range i.e. 5th = 10.5.x.x. 

Is there anyway of doing this using dynamic grouping?
