help DigitalOcean Reserved IPv4s FAQ
Can a DigitalOcean Reserved IPv4 move to another Droplet?
A reserved address is designed to remain available when reassigned between Droplets. This supports failover and migration without changing the public address used by a service.
Why would a developer reserve an IPv4 address?
A stable address is useful for DNS targets, firewall allowlists, APIs, databases, and remote administration. It avoids tying a service's identity to one temporary Droplet address.
Does a Reserved IPv4 survive a Droplet reboot?
Yes, its purpose is to stay attached through ordinary Droplet restarts. It can therefore provide a predictable entry point for a web or development server.
What should be checked before using a Reserved IPv4 in production?
Confirm the current DigitalOcean pricing, attachment rules, firewall configuration, reverse DNS needs, and IPv4 availability. The address alone does not provide backups, failover automation, or application health monitoring.
