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
