In the Subgrouping function in ITAM you cannot update IP address. Where this is needed is if you have bought 3 servers in bulk and want to update IP address when subgrouping you cannot. You can change the name, host name, dns and Mac. When setting up a production server, the IP address is static and needs tracked if using CMDB or IT needs to know how to find it. Can use IP to get general idea where in the network it is located.
