Hello Support,

We would like to clarify the purpose and working behavior of the “Add IP Address” option in Plesk.

Could you please confirm the following:

1. What is the exact use of the Add IP Address option in Plesk?
2. If we add an IP address in Plesk, does it only register the IP inside the Plesk panel, or does it also configure the IP at the server/network level?
3. Do we need to first obtain and configure an additional public IP address from our data center/provider before adding it in Plesk?
4. If the additional public IP is not routed/configured on the server by the data center, will adding it in Plesk alone work?
5. What are the recommended steps to properly add and assign an additional public IP address for hosting websites/subscriptions in Plesk?

Please advise the correct procedure, so we can avoid any network or website accessibility issues.
