-Q: Why is there no v6-support in opentracker?
-
-A: Although I tried very hard, implementing v6 right now would be a terrible waste of bandwidth, there is no compact format for v6 addresses, so instead of
-answering "d5:peers6:AAAAPPe" I'd have to send "d5:peersld2:ip39:AAAA:AAAA:AAAA:AAAA:AAAA:AAAA:AAAA:AAAA4:port2:PPPPeee" for a single peer. Even if there was a
-compact mode, v6 addresses still would eat up thrice the memory, v4 addresses take. This, however, wouldn't be a show stopper.
-
-Other problems concern efficient peer selection for obviously v6-capable peers and how to select peers for non-v6 clients. v6 addresses eat up more memory on the
-host, too ;)
+IPv6 is implemented in opentracker now. You can chose whether your tracker runs in v4 or v6 mode in Makefile. YMMV.
