Portable public IPs
Reserve an IPv4 address and attach it to whichever interface needs public ingress. Move the address between interfaces when the target changes.
Dedicated public IPv4
Attached to one interface at a time
Reassignment via API and console
Billed hourly while allocated
Subject to the region's floating IP quota
Shares the quota with NAT EIPs
Flexibility for operational HA
Failover
Move the IP to another interface in seconds during an outage.
Blue/green
Switch the target without touching DNS or allowlists.
Maintenance
Keep the public address while you replace the instance behind it.
Static IP
A fixed address for integrations and allowlists.
How it works today
A floating IP stays attached to a single interface. To spread traffic across replicas, use a load balancer.
Attach to an interface
Associate the floating IP with a network interface in the VPC (with an egress route through an internet gateway).
Reassignment
Detach and attach it to another interface from the console or API.
Dedicated IPv4
An address exclusive to your account while it stays allocated.
