Key concepts and terms

• Ephemeral IP addresses are temporary and tied directly to a specific resource rather than your account. They are typically recycled once the associated resource is deleted. Use ephemeral IP addresses for standard web traffic that doesn't require a permanent, static IP.
• Reserved IPs are static, permanent addresses ideal for services requiring a consistent entry point. A reserved IP is permanently bound to the specific region where it was created. You can create a reserved IP independently of a resource, allowing it to exist on your account with or without an active assignment. Charges apply as soon as a reserved IP is added to your account, regardless of whether it is assigned to a resource. Use reserved IPs for services that require a consistent IP address.

Reserve an IP address

You can reserve individual public IPv4 addresses in the following ways:

• Independently, for future assignment.
• When deploying a new Linode or NodeBalancer.
• By converting an assigned IP that is already in use into a reserved one.

🚧

Selecting a target region for reserved IPs

During this process, you must define the target region where the IP will live. Because reserved IPs are bound to a specific datacenter's network infrastructure, the address can't be moved to a different region later. Ensure your intended Linodes or NodeBalancers reside in this same region.

Review the Reserve an IP guide for complete instructions.

Manage and assign reserved IPs

After you reserve an IP, you can assign to a new resource within the same region, edit it, or unreserve it from your account.

See the Manage and assign reserved IPs guide for complete instructions.
