Hi, Digital ocean has something called a "Floating IP Address" which is a static Address that can be move from one virtual machine to another. Each virtual machine gets its own address a creation that lasts until it is destroyed. The Floating IP lets you change the VM it points to vey quickly for disaster recovery or even upgrades. I found this: https://gist.github.com/sanderkwantes/3ab81f2d3d6ee182fa237bbc3f5c1489 explaining how to use a D.O. Floating IP, and it works. It says add this to vars.xml <X-PRE-PROCESS cmd="exec-set" data="local_ip_v4=ip addr show eth0 | awk 'FNR == 5 {print $2}' | cut -d '/' -f 1"/> BUT, when I do that, the old (still valid) IP Address can no longer be used to register. Tis makes a transition through my DNS from one to other very difficult. Is there a way to allow 2 valid IP address in a single instance of FS? Thanks, Sean
