Hi everyone. I believe that ptlis01 is isolated. I can access ipv6 within pop but cannot do it outside pop. Hope this help: ping6 ptlis01.sixxs.net -c 2 PING ptlis01.sixxs.net(2001:b18:0:1000:2e0:81ff:fe61:ae0d) 56 data bytes 64 bytes from 2001:b18:0:1000:2e0:81ff:fe61:ae0d: icmp_seq=1 ttl=64 time=13.0 ms 64 bytes from 2001:b18:0:1000:2e0:81ff:fe61:ae0d: icmp_seq=2 ttl=64 time=12.3 ms --- ptlis01.sixxs.net ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1013ms rtt min/avg/max/mdev = 12.339/12.701/13.063/0.362 ms ping6 ipv6.google.com -c 2 PING ipv6.google.com(lis01s06-in-x13.1e100.net) 56 data bytes --- ipv6.google.com ping statistics --- 2 packets transmitted, 0 received, 100% packet loss, time 10999ms ping6 ipv6.cnn.com -c 2 PING ipv6.cnn.com(2620:100:e000::8001) 56 data bytes --- ipv6.cnn.com ping statistics --- 2 packets transmitted, 0 received, 100% packet loss, time 10999ms traceroute to ipv6.cnn.com (2620:100:e000::8001), 30 hops max, 80 byte packets 1 2 2001:b18:0:1000:2e0:81ff:fe61:ae0d (2001:b18:0:1000:2e0:81ff:fe61:ae0d) 12.229 ms 12.284 ms 12.661 ms 3 2001:b18:0:1000::1 (2001:b18:0:1000::1) 13.132 ms 13.188 ms 13.273 ms 4 2001:b18:0:f:1::5 (2001:b18:0:f:1::5) 23.658 ms 23.741 ms 23.786 ms 5 2001:b18:0:f:1::e (2001:b18:0:f:1::e) 31.740 ms 31.826 ms 31.890 ms 6 * * * 7 * * * 8 * * * 9 * * * 10 * * * ...
