IPV6 connectivity to fireball.acr.fi is failing inside Cogent AS174. I have already contacted the Cogent NOC, but I haven't heard anything back yet. I'm wondering if somebody else with Cogent IPV6 connectivity can run some tests. IPV4 connectivity is working fine.
It works from AS2547 through Cogent: PING6(56=40+8+8 bytes) 2001:738:2001:2001::c --> 2001:1bc8:100d::2 16 bytes from 2001:1bc8:100d::2, icmp_seq=0 hlim=52 time=57.356 ms 16 bytes from 2001:1bc8:100d::2, icmp_seq=1 hlim=52 time=57.499 ms 16 bytes from 2001:1bc8:100d::2, icmp_seq=2 hlim=52 time=57.889 ms ^C --- fireball.acr.fi ping6 statistics --- 3 packets transmitted, 3 packets received, 0.0% packet loss round-trip min/avg/max/std-dev = 57.356/57.581/57.889/0.225 ms traceroute6 to fireball.acr.fi (2001:1bc8:100d::2) from 2001:738:2001:2001::c, 64 hops max, 12 byte packets 1 vl100.taz.net.bme.hu 0.730 ms 0.389 ms 0.369 ms 2 tg0-1-0-1.rtr.bme.hbone.hu 1.116 ms 0.839 ms 0.590 ms 3 * * * 4 2001:978:2:27::7:1 1.227 ms 0.979 ms 0.942 ms 5 * * * 6 * * * 7 * * * 8 * * * 9 * * * 10 * * * 11 * * 2001:978:2:3f::6 46.962 ms 12 2001:1bc8:1:7:0:d:0:1 47.060 ms * 47.309 ms 13 2001:1bc8:100:100:5::2 55.083 ms !N 54.830 ms !N 62.167 ms !N $ telnet -6 fireball.acr.fi 80 Trying 2001:1bc8:100d::2...
