I guess there's something wrong at my end. If I keep trying to connect, after 6 or 7 hours of trying it connects. And if I restart my router and get a new dynamic IP, I have to wait another 6 hours to get a connection. I've now moved entirely to OpenDNS, but still my system requests the hashnet IP address from DNS and gets no answer. When it connects, that should be after about 4 hours, I'll write down the IP of hashnet.org, restart the router and try connecting directly.
