Adding and Removing IP Addresses

After installation, Plesk reads all your IP addresses from the network configuration files and can then use these IP addresses for hosting DNS domains and Web sites.

When you obtain a new IP address that you would like to use on the server, you should add the address through the control panel, as Plesk might not recognize manual modifications you make to the network configuration files.

With Plesk you can mark all your IP addresses as shared or dedicated before you assign them to your customers. This allows the control panel to distinguish between them and not to let you assign a dedicated IP address to several customers at once. A dedicated IP address can be assigned to a single customer, while a shared IP address can be shared among several user accounts.

Note that SSL protection with authentic digital certificates and Anonymous FTP services are available only to dedicated hosting accounts on a dedicated IP address. Shared hosting accounts can also have SSL protection, but visitors to such protected sites will get error messages in their browsers.

Note: in this version of Plesk control panel, dedicated IP addresses are referred to as Exclusive IP addresses.
