The options file can control seat usage using IP address. You can find out more about options files in the following Article:

Is there a way to administer FLEXnet based licenses? How do I create an Options file?

To to reserve or limit keys for IP addresses or a specific subnet, you can use the INTERNET option. Below are some examples.

To reserve 5 keys of MATLAB for users on the subnet 177.35.40.*:

RESERVE 5 MATLAB INTERNET 177.35.40.*

To reserve 2 keys of Simulink for users on the subnet 177.35.41.*:

RESERVE 2 Simulink INTERNET 177.35.41.*

To limit the number of keys of MATLAB to 3 for users on subnet 179.37.64.*:

MAX 3 MATLAB INTERNET 179.37.64.*

To limit the number of keys of Simulink to 1 for users on subnet 179.37.62.*:

MAX 1 Simulink INTERNET 179.37.62.*

There is no way to set up a group of subnets to reserve or limit license keys. For example, the following is NOT possible:

MAX 3 MATLAB INTERNET 179.56.85.* 179.56.84.*

The only workaround for this is to use hostnames or individual IP Addresses. You can set up a HOST_GROUP with a list of all of the hostnames or specific IP Addresses you wish to reserve or limit the license keys for:

HOST_GROUP group_name host1 host2 host2...

Then, use this in your RESERVE or MAX line:

RESERVE 5 MATLAB HOST_GROUP group_name
MAX 3 Simulink HOST_GROUP group_name
