 We are using two standards: the domain name system [(DNS)](https://datatracker.ietf.org/doc/html/rfc1035) and [Pkarr](https://app.pkarr.org/). DNS is typically used for resolving domain names into their associated IP addresses. But DNS actually relates _domain names_ to [_resource records_](https://datatracker.ietf.org/doc/html/rfc1035#section-3.2), of which IP addresses are one type. Pkarr allows us to publish DNS records that resolve **elliptic curve keys** (not domain names) to resource records instead. Our **Node IDs** in iroh are elliptic curve public keys. This means we can publish an association between iroh Node IDs and some resource records. Importantly, these records are signed, so that you can verify that the record was actually published by the node with the given Node ID.
 
-As long as iroh has a Node ID and it’s associated relay URL (the address of the relay server that node uses to hole-punch and proxy relay packets), we can dial that node. So the Pkarr packet currently only needs to contain the Node ID and the relay URL of it’s preferred relay server (which we call its “home relay”). When Pkarr publishing is enabled on your iroh node, your node will create a Pkarr packet with its Node ID and relay URL, sign it, and defaults to publishing on an  `iroh-dns` server that is run by number0.

 From there, others can discover your dialing information by resolving your Node ID using regular DNS. It’s worth noting that others must still learn your node ID for this to work,
