I second this request, however, is slightly different to the private interface your referencing @girish

x1 server, 5 public interfaces (eth0-5) all with public static IP's.

In my scenario, a client would be assigned a single static IP for all their applications. I'm doing this currently by spinning up an individual VPS on Runcloud for their apps. The main advantage for them is RDNS for their 'assigned' IP address.

Just my 2cents
