Hetzner

Floating IPs

Hetzner Floating IPs are re-assignable IPv4 and IPv6 addresses designed for failover setups across cloud servers within a single location. This networking service allows you to quickly redirect traffic between instances, ensuring high availability without changing DNS records or waiting for propagation. It serves as a static public endpoint that can be moved to a backup server if the primary one fails, maintaining continuous service for your applications.

You should choose this solution when you need reliable failover mechanisms for your cloud infrastructure in a specific geographic area. However, be aware that there is no free tier available for this service, and it operates on a pay-as-you-go pricing model. This means you will incur ongoing costs for every floating IP address assigned to your servers, so monitor your usage to avoid unexpected charges.
