// We may know a NodeID (with a mask) and want to connect
|

// We begin a search by initializing a list of all nodes in our DHT, sorted by closest to the destination
|

// We add any unvisited nodes from ping responses to the search, truncating to some maximum search size

|

// A new search packet is sent immediately after receiving a response
