I’ve been using Digital Ocean droplets as WireGuard VPN servers. The VPN service uses an internal set of IP addresses, for which I wanted to use 10.A.B.X (where A and B are randomly chosen for each droplet, and X is a separate ID for each client user).
However, I notice that there’s an “Anchor IP” associated with eth0 on each droplet, even when I don’t use Floating IPs. This is fine, but I want to make sure that my randomly chosen IP scheme doesn’t conflict/overlap with the Anchor IP.
So, if I choose A and B to always be between 30 and 250, will that avoid conflicts, or do some droplets use 10.30.x.x as the anchor IP? What range can I use to ensure I don’t overlap?

Hi there @jasongyorog,
I believe that the Anchor IP that you are referring to is the IP address of your VPC IP range.
If you go to your DigitalOcean Control Panel -> Then go to “Networking” -> After that click on VPC -> there you could see all of your VPC IP ranges.
Hope that this helps! Regards, Bobby
