Activation of PSU

Product: PowerShell Universal
Version: *.*.*

Thanks for a great work, I really like this product!

We are trying to setup a test server (using developer license) in our test enviroment to verify upgrade new version before we do it in our production. but the enviroment is lockdown, so I need to request firewall opennning for internet access.

after checking firewall logs, I saw it tried to access www.ironmansoftware.com every 5 minutes, and the notification in admin ui shows the same.

may I assume the license activation goes to www.ironmansoftware.com only?
