Reserved IP Details
DigitalOcean Reserved IPs are publicly-accessible static IPv4 addresses. Assign and reassign reserved IP addresses to Droplets as needed, or implement an automated failover mechanism with reserved IPs to build a high availability infrastructure. IPv6 support is now available in public preview. Enroll in the feature preview to create reserved IPv6 addresses.
Reserved IPs let you redirect network traffic between any of your Droplets within the same datacenter. Assigning a reserved IP to a Droplet doesn’t replace or change its original public IP address.
All reserved IPs are free when assigned to a Droplet.
Reserved IPv4 addresses are available in all datacenters.
Reserved IPv6 address are available in all datacenters. During the public preview you must opt-in to the feature to create reserved IPv6 addresses.
