Flexible IPs

A flexible IP address is an IP address which you hold independently of any server. You can attach it to any of your server and do live migration of the IP address between your servers.

Be aware that attaching a flexible IP address to a server will remove the previous public IP address of the server and cut any ongoing public connection to the server.

When you delete the flexible IP, it is disassociated from your account to be used by other users. You can reserve IP addresses in the Control Panel. You then have to configure which server gets which flexible IP.
