4.2 Registering a Name
To register a Peer Name, a node performs the resolve operation as specified in section 4.1.3, with the Target ID set to the PNRP ID to be registered + 1. For example, if PNRP ID 6 were being registered, it would perform a resolve operation seeking PNRP ID 7.
As other nodes receive LOOKUP messages from the registering node, they add the registering node's PNRP ID to their Leaf Sets when appropriate. Likewise, the registering node will populate its own Leaf Set with the PNRP IDs that it finds in the received AUTHORITY messages.
