You are using IPv6 from 3ffe:8114:2000:240:200:39ff:fe77:1f3f Thus IE6/Win2k works and I expect most others supporting IPv6 to do so also ;) As for latency: IPv6: 10 packets transmitted, 10 received, 0% packet loss, time 9097ms rtt min/avg/max/mdev = 174.092/175.407/178.517/1.313 ms IPv4: 10 packets transmitted, 10 received, 0% packet loss, time 9086ms rtt min/avg/max/mdev = 187.186/190.781/199.164/3.799 ms Looks the same to me, IPv6 is even a fraction better.. hmm ;) <lobby> Shall I add that host, or one near it, to: http://www.sixxs.net/misc/latency/ ? Routing glitches can be seen quite well in that system. Btw, is there a ISI Looking Glass or similar system available so that it can be included into GRH (http://www.sixxs.net/tools/grh/) ? Check the LG on the last url shows that ASN4554 does quite some transit even between europe -> us and back to europe again... Ofcourse everybody else with an AS who like to share their view onto the world can take a look. </lobby> Greets, Jeroen
