Additional IPs

imadsani

Hello,

I apologize if this has been asked before.

But how can I add additional IP addresses to a server?

I have client's that do not share DNS access (nameserver changes either), so to get around this I use Hetzner's Floating IP's for redundancy. This enables me to move the client domains between servers without ever having to go through them.

Enhance isn't aware of secondary IPs on a system. However, you can bind IPs to the system and the web server which listens on 0.0.0.0 will serve your websites on that IP which should give you the functionality you require.

You just need to bind the alias addresses to your network interface in Ubuntu. How you do this depends how the existing IPs are managed, you probably want to configure it with netplan.
