IPv6 access to ftp.ripe.net
by James Aldridge 28 Jun '06

28 Jun '06

[Apologies for duplicate e-mails] Dear Colleagues, IPv6 access to ftp.ripe.net is currently not possible. IPv4 access is unaffected. The current ScreenOS firewall software is unable to support extended passive-mode FTP. We have therefore temporarily removed the AAAA record for ftp.ripe.net from the DNS. We hope to restore IPv6 access as quickly as possible and will inform you when this occurs. We apologise for any inconvenience. Regards, James Aldridge Systems & Network Engineer RIPE NCC Operations Group

6to4 address utilisation
by Thu Thuy 09 Jun '06

09 Jun '06

Hi, I have a question about 6to4 address utilisation. May i post it here ? Thanks everyone for your guidance. 6to4 is a tunnel method. From an IPv4 address, we have /48 6to4 IPv6 space. So i'm wonder if this /48 range can be commonly used for our IPv6 network (workstations, servers) like native IPv6, or it just be used only for tunnel, to connect native IPv6 lands. Thank you once more, Thu Thuy Development & Research Department. Vietnam Internet Network Information Center - VNNIC.

Hi! I see v6 connectivity is much worse than v4: traceroute to kite-www.ripe.net (2001:610:240:0:a843::8) from 2a01:d8:0:99:211:11ff:fe1f:bfc9, 30 hops max, 16 byte packets 1 2a01:d8:0:99::1 (2a01:d8:0:99::1) 0.782 ms 0.719 ms 2.227 ms 2 2a01:d8:0:1::1 (2a01:d8:0:1::1) 40.904 ms 2.346 ms 2.754 ms 3 2001:b08:0:2::1 (2001:b08:0:2::1) 35.849 ms 7.533 ms 2.576 ms 4 2001:b08:b08:3::2 (2001:b08:b08:3::2) 35.205 ms 25.399 ms 25.649 ms 5 se-kth.nordu.net (2001:948:0:f02c::1) 29.649 ms 25.579 ms 25.545 ms 6 se-ov.nordu.net (2001:948:0:f027::2) 33.705 ms 25.539 ms 25.927 ms 7 dk-gw2.nordu.net (2001:948:0:f03f::2) 39.785 ms 33.901 ms 33.688 ms 8 * * * 9 * * * 10 * * * 11 * * * 12 nikipv6.ripe.net (2001:7f8:1::a500:3333:1) 214.93 ms 226.989 ms 215.676 ms 13 kite-www.ripe.net (2001:610:240:0:a843::8) 214.484 ms 215.588 ms 221.891 ms 1: greentheatre (195.209.50.18) 0.273ms pmtu 1500 1: gw.gpt.ru (195.209.50.1) 1.366ms 2: LEO-MG-2.Garnet.ru (195.209.63.20) 57.568ms 3: d2-msk-m9-ge0-0-0-v102.ruscomnet.ru (80.249.128.117) asymm 4 3.034ms 4: c1-msk-m9-ge0-1-0.ruscomnet.ru (80.249.132.9) asymm 5 4.265ms 5: d1-fft-as0.ruscomnet.ru (80.249.132.26) asymm 6 51.486ms 6: gigabitethernet3-0.104.gw9.fft4.de.ALTER.NET (139.4.144.5) 51.952ms 7: so-7-1-0.XR1.FFT4.ALTER.NET (149.227.48.25) asymm 8 52.247ms 8: so-0-1-0.TR2.FFT1.ALTER.NET (146.188.8.138) asymm 9 52.400ms 9: so-5-1-0.TR2.AMS2.ALTER.NET (146.188.2.169) asymm 10 58.617ms 10: POS2-0.BR1.AMS3.ALTER.NET (146.188.3.218) 58.315ms 11: Amsterdam1.ripe.net (195.69.144.68) 53.182ms 12: kite.ripe.net (193.0.0.214) asymm 11 53.245ms reached Resume: pmtu 1500 hops 12 back 11 And some parts of v6 Internet is completly unreachable.
