All calls to Software Potential WCF web services go to srv.softwarepotential.com.
Activation calls from the Software Potential Runtime on end-user machines etc. (i.e., protected code which requires activation by key) travel (over standard port 80) to http://srv.softwarepotential.com/SLMServerWS/ActivationWS.svc by default.
It is also possible to also send activation requests over a secure channel (on standard port 443) to https://srv.softwarepotential.com/SLMServerWS/ActivationWS.svc/SSL.
It is thus important that client firewalls, proxies etc. are configured to allow calls to http://srv.softwarepotential.com [on port 80 and 443] unimpeded.
These activation endpoints do not require authentication.
License Management Endpoints
Calls to the licensing APIs (e.g. for automation of license issuance, if you are integrating with your end-to-end software distribution system etc.) travel over HTTPS (over standard port 443) to https://srv.softwarepotential.com/SLMServerWS/LicenseManagementWS.svc.
The license management endpoints do require authentication with valid credentials of a Software Potential service account owner.
