 Features:
 * regularly revisits known nodes to check their availability
 * bans nodes after enough failures, or bad behaviour
-* accepts nodes down to protocol version 180004 to request new IP addresses from,

 * keeps statistics over (exponential) windows of 2 hours, 8 hours,

 * very low memory (a few tens of megabytes) and cpu requirements.
