Why can Floating IPs not be moved between data centers?

According to this, Floating IPs can

be instantly remapped, via the DigitalOcean Control Panel or API, to one of your other Droplets in the same datacenter

What prevents Floating IPs from pointing to Droplets in different data centers?

Because of the inherent workings of Internet routing and the sizes of the blocks allocated to network service providers.

If you are just want load balancer for http/https traffic take a loot at our SaaS Load Balancer https://failovery.com

It is possible to have a floating IP between datacenters. Amazon Elastic IP’s do it within the same region. IBM cloud (formerly softlayer) has the best implementation I have found since there is no regional limitation and no NAT involved. They call it global IP.

  • That’s nice and all…but doesn’t really address why DO doesn’t do it :)

    • Actually it does. IBM cloud shows that it is possible. There are some here suggesting that DO does not do it because it is not possible. It is not done because it is not easy. If it were, IBM cloud would not be one of if not the only service that does it.

      If DO were to do it they would certainly get my business. Floating IP is not useful to me without datacenter redundancy.

Also want to add that there is another company that does it in addition to IBM cloud. Their service looks even better in some ways because it includes the monitoring and automatic failover features.
