4D applications will communicate with server addresses to send files to validate licenses or collect 4D Server statistics. Occasionally, and especially within strict network rules, these server addresses might be blocked by the firewall.

In this case, 4D developers usually need to whitelist IP addresses and domains to which 4D applications phone home. Here are the two domains 4D uses:

• autoregistration.4d.com -  IP address: 195.68.52.83


• dcollector.4d.com - IP address: 74.82.63.126

The autoregistration is used to refresh licenses when needed.

The dcollector is from 4D Server to collect usage data once a week.

You can read more about 4D and data collection in the documentation.
