For Windows, run the LM-X End-user Configuration Tool (lmxconfigtool.exe) to see your machine's HostIDs, as shown in the following example.
In the above example, you can see that you can lock your license to IP address 192.168.64.123 using its corresponding HostID, 192.168.64.123 (the HostID may not be identical to the IP address).
The IP addresses that include asterisks may be thought of as wildcards. You can use the HostIDs of these IP addresses to lock licenses to a subnetwork if needed, allowing wider access.
For Linux, run the LM-X end-user utility using the -hostid option (lmxendutil -hostid) at a command line to see the list of your machine's HostIDs.
