# Reserved IP

A reserved IP is a public IPv4 address that belongs to your account rather than to one
resource. It stays yours until you delete it, even after the node it was attached to is gone.
A domain, a partner's allow list, or a client with a fixed address can keep pointing at it
while you change what sits behind it.

Say you move a website to a new node on a different plan. If the site's DNS record points at a
reserved IP, you attach that address to the new node and the site answers there, with no DNS
change to wait for.

A reserved IP can do three jobs:

- A node's primary public IP, chosen when you create the node or attached later.
- An Add-on IP: a second public address on a node or a [Firewall](/myaccount/firewall/), next to the one it already
  has.
- A Floating IP: one address shared by up to four nodes, so a service can fail over from one
  node to another without its address changing.

## What you can do with a reserved IP

- [Reserve an IP](/myaccount/reserved-ip/how-to/reserve-an-ip/), fresh from the pool or by
  keeping the public IP a resource already has.
- [Attach a reserved IP as an Add-on IP](/myaccount/reserved-ip/how-to/attach-a-reserved-ip-as-an-add-on-ip/)
  to a node or a firewall.
- [Attach a reserved IP to a node](/myaccount/node/how-to/attach-a-reserved-ip/) as its primary
  public IP.
- [Use a reserved IP as a Floating IP](/myaccount/reserved-ip/how-to/use-a-reserved-ip-as-a-floating-ip/),
  then [set up failover with a Floating IP](/myaccount/reserved-ip/how-to/set-up-failover-with-a-floating-ip/).
- [Reserve a node's public IP when you delete it](/myaccount/reserved-ip/how-to/reserve-a-nodes-public-ip-when-you-delete-it/).
- [Move a reserved IP to another project](/myaccount/reserved-ip/how-to/move-a-reserved-ip-to-another-project/).
- [Request a higher reserved IP limit](/myaccount/reserved-ip/how-to/request-a-higher-reserved-ip-limit/).
- [Delete a reserved IP](/myaccount/reserved-ip/how-to/delete-a-reserved-ip/).

## Where to start

[Get started with Reserved IP](/myaccount/reserved-ip/get-started/) reserves an address and
attaches it to a node. [Reserved and Floating IPs](/myaccount/reserved-ip/concepts/reserved-and-floating-ips/)
explains the two modes and what each status means.
