Floating IPs

Last updated 20 February 2026

Overview

A floating IP is a static, public IPv4 address that you can assign to any server in the same data centre. Unlike the server's primary IP, a floating IP can be instantly reassigned to another server — useful for high availability and failover.

Create a Floating IP

  1. Go to Networking → Floating IPs in the dashboard.
  2. Click Create Floating IP.
  3. Select the data centre (Lisbon or Johannesburg).
  4. Optionally assign it to a server immediately.
  5. Click Create.

Assign and Reassign

A floating IP can be reassigned between servers instantly — no DNS propagation needed. This makes it ideal for:

  • High availability — move the IP to a standby server if the primary fails
  • Blue/green deployments — switch traffic between old and new server versions
  • Maintenance — redirect traffic while performing upgrades

Server Configuration

After assigning a floating IP, you may need to configure the server to listen on it. The exact steps depend on your operating system. On most Linux distributions:

# Check if the IP is visible
ip addr show

In most cases, the floating IP is routed to the server's primary network interface automatically and no additional configuration is required.

Pricing

Floating IPs are billed per IP per month. An unassigned floating IP still incurs charges — release it if you no longer need it.
