A list of the fixed IP addresses your provider has reserved for you, showing which server each one points at and what you're paying for the ones pointing at nothing — for anyone managing servers who wants to avoid paying for unused addresses.

## Overview

- A reserved IP address (your provider may call it a floating IP, an elastic IP or a primary IP) belongs to your account, not to a particular server — you can move it from one server to another.
- InfraNest lists every reserved address found on your connected cloud accounts, along with the server it's attached to, its reverse-DNS name, its location and its monthly cost.
- This list is read directly from your provider, so it's never out of date: an address reserved or released in your provider's console shows up here on the next sync.

## Find addresses you're paying for but not using

1. Go to **Servers**, then open **IP addresses**.
2. Read the banner at the top of the list — it counts unattached addresses and totals their monthly cost.
3. Look down the Server column for any blank entries. A blank Server column means that address isn't attached to anything.

> [!WARNING]
> An unattached address isn't always a mistake. Some are kept on purpose — for maintenance, or because they're already registered in DNS or allow-listed by a partner. Releasing one of those loses the address for good. InfraNest won't release an address for you, because it can't tell which situation you're in.

## Check an address's reverse DNS

1. Go to **Servers**, then open **IP addresses**.
2. Find the address you want to check and read the Reverse DNS column — this shows the PTR record, which is what a mail server or a log reader sees when your machine connects to it.
3. To change it, open the server the address is attached to and go to its **Networking** tab — reverse DNS is edited there, not on this page.

## Move an address to another server

1. Moving a reserved address between servers is done in your provider's console, not in InfraNest.
2. Once you've moved it there, InfraNest will pick up the change automatically the next time it syncs with your provider.

> [!NOTE]
> This page is a live read from your provider, not a separate record you need to keep in sync — there's nothing to reconcile here.

## Tips

- Check this page occasionally after deleting a server — its reserved address may be left behind, still costing money, and it won't appear anywhere on a server's own page since it's no longer attached to one.
