The AutoNAT service implements the [AutoNAT protocol](https://libp2p.io/docs/autonat/)
to confirm whether addresses the node is listening on are dialable by remote
peers.

It does not implement NAT hole punching.

> \[!IMPORTANT]
> [AutoNat v2](https://www.npmjs.com/package/@libp2p/autonat-v2) is now
> available and should be preferred to this module.

## Example

```typescript
import { createLibp2p } from 'libp2p'
import { autoNAT } from '@libp2p/autonat'

const node = await createLibp2p({
  // ...other options
  services: {
    autoNAT: autoNAT()
  }
})
```

# Install

```console
$ npm i @libp2p/autonat
```
