# Elastic IPs

Elastic IPs (Floating IPs) are publicly-accessible static IP addresses that you can assign to Instances and instantly remap between other Instances in the same region.

You can use elastic IPs to create server infrastructures without single points of failure, but a elastic IP alone does not automatically provide high availability. For a setup to be highly available, you need to implement a failover mechanism to automate the process of detecting failures of the active server and reassigning the elastic IP to a passive server.

## Plans and Pricing

One Elastic IPs is free when assigned to a Instance. For pricing details please consult our [pricing page](https://flow.swiss/pricing#compute).

## Regional Availability

Elastic IPs are available in all regions. They are region-specific resources and can only be assigned within the same region.

## Limits

* Elastic IPs cannot be assigned to more than one instances at a time.<br>
* At the moment, we do not support IPv6 elastic IPs. All elastic IPs are IPv4.<br>
* Reverse DNS Records (rDNS) have to be requested via support ticket.
