Question

Does the Anchor IP always remain fixed

Posted June 4, 2017 4.1k views
CentOSConfiguration Management

I use a php script to find out which server it is running on by looking at the server IP. When using a floating IP the IP returned is the Anchor IP. Once an Anchor IP is allocated to a particular server is this IP fixed? Can I guarantee it will not change over say a reboot or will Digital Ocean systems ever reallocate a different Anchor IP to the server?

Hi @altekgm

The IP addresses you get when you create a Droplet or Floating IP is yours until you stop the service. I’ve never heard of a IP being changed.
In any case DigitalOcean needs to do something different, they will notify you in advance.
just like they do today, if the need to upgrade a physical node, then they give you advanced notice of a pending reboot - and you can even contact them to have the reboot done at a different time.
