If you manage a virtual environment with Proxmox VE, there may come a time when you need to change the IP address of a host. This can happen if you’re reorganizing a datacenter, moving offices, or migrating a host to a new provider. Doing it correctly ensures your virtual machines stay connected and your management access remains uninterrupted.

Proxmox hosts typically use a static IP for management, though DHCP is an option. The main IP handles host management, while additional IPs may serve storage networks or routed VM networks. This guide focuses on updating the primary IP used for managing the host.

There are two ways to change the IP: command line interface (CLI) and Proxmox web interface. Using the CLI, you connect via SSH, gain root privileges, and edit the /etc/network/interfaces file to assign a new IP and gateway. Updating the /etc/hosts file is also required to ensure proper hostname resolution. After saving changes, restart the networking service or reboot the host.

Alternatively, the web interface allows you to perform the same updates through a GUI. Navigate to System → Network, select the interface, edit the IP and gateway, and apply the changes. The /etc/hosts file can also be updated directly within the web UI to reflect the new IP.

For Proxmox clusters, changing a node’s IP is more complex. You need to stop cluster services, update Corosync and network configurations, and restart services carefully to avoid disruptions. It’s recommended to handle one node at a time and back up all configuration files before making changes.

Changing the Proxmox host IP is straightforward when you follow the right steps. Whether you’re a new user or an experienced admin, these methods help keep your virtual environment running smoothly.
