It is not possible.
You need a license for every IP (server) running a SFS instance.
There is a license server tool for this situations:

It lacks only one feature:
The
license request with a license type instead of license id.
This is required for situation like building a cloud based system which can scale up/down when needed by launching new servers in the cloud when needed.
In a system like this, it is not possible to configure the newly launched server to use a specific license id. It must request a license from the server by sending the
license type it wants and then license server will pick one of the available from a pool of that license type and hand it to the newly launched sfs intance.
