By default, iroh will use public shared relays to facilitate connections over DNS. These relays handle both forwarding traffic when direct peer-to-peer connections are not possible as well as facilitate holepunching for direct connections. These relays are managed and maintained by the n0des team, and are shared by a global public network of developers. By default, all iroh endpoints will use the public cloud relays unless you purchase a managed relay or deploy your own self-hosted relay.

​
Self-Hosted and Managed Relays

If you require more control over your relay infrastructure, you can choose to self-host your own relay or upgrade to a managed relay service. This allows you to have full control over the relay servers, including their configuration, security settings, and access controls.
