Put a limit on the nodes returned on a findnode request 2020-12-17 17:06:42 +01:00

Use of discv5.1 findnode request with multiple distances 2020-12-17 15:42:04 +01:00
kdeme a506739b23
Add query proc and use this for recurrent queries 
This query proc is similar to the original (faulty) lookup proc.
But as we don't need to look for specific targets, it can be
used still as it gives a quicker and broader search resulting
in more nodes.
