Implementation of Autonat Protocol
The AutoNAT service uses the AutoNAT protocol. The service confirms addresses are dialable by remote peers, and updates the list it advertises.
The service dials randomly selected peers with a request to verify it's external addresses. The request includes a list of public multiaddrs (addressManager.getObservedAddrs()). The remote peers dial that list and respond with the results.
The AutoNAT service uses those responses to either:
- addressManager.confirmObservedAddr(addr)
- addressManager.removeObservedAddr(addr)
The result list of candidates and confirmed addresses can be found at addressManager.getObservedAddrs()
import { createLibp2p } from 'libp2p'
import { autoNAT } from '@libp2p/autonat'
const node = await createLibp2p({
// ...other options
services: {
autoNAT: autoNAT()
}
})$ npm i @libp2p/autonatLoading this module through a script tag will make its exports available as Libp2pAutonat in the global namespace.
