# Reserved IP Availability

DigitalOcean Reserved IPs are publicly-accessible static IPv4 and IPv6 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.

Reserved IPv4 addresses are available in all datacenters.

Reserved IPv6 addresses are available in all datacenters.

All reserved IP addresses are region-specific resources and can only be assigned to Droplets within the same datacenter.

BYOIP is available in all datacenters. Each BYOIP prefix exists in a single datacenter and is available only to resources in that datacenter.
