BTW. What geolocation database is debian NS servers use for IPv6? For example it thinks my tunnel which have endpoint in Frankfurt or Amsterdam are in NA (North America), not EU. :( For example for Hurrican Electrics it have lots of end points and (based on my own info, info from webpage, dns and from telnet route-server.he.net.) for example tserv6.fra1.ipv6.he.net (2001:470:0:6a::1, 216.66.80.30) serves a 2001:470:1f0b::/48 is located in Frankfurt, DE near core1.fra1.he.net router: Interxion Frankfurt 216.218.252.174 2001:470:0:2a::1 tserv11.ams1.ipv6.he.net (2001:470:0:7e::1, 216.66.84.46) serves a 2001:470:1f15::/48 is located in Amsterdam, NL near core1.ams1.he.net router: NIKHEF Amsterdam 216.218.252.173 2001:470:0:e::1 tserv28.waw1.ipv6.he.net (216.66.80.162) serves a 2001:470:71::/48 is located in Warsaw, PL near core1.waw1.he.net router: PLIX Warsaw 216.218.252.189 2001:470:0:215::1 This servers also serves other /48 blocks, but they are rare, because normally they allocate /64 subblocks from this /48 mentioned above. `dig -6 -TXT www.debian.org @geo1.debian.org` thinks I'm in NA. All servers listed here http://tunnelbroker.net/status.php and core routers using telnet router-server.he.net I however do not know how to extract all prefixes for each server easly. I know tunneled connections are problematic, but still as my IPv6 address is essentially behind router/server in Frankfurt, it should be mapping me to Europe at least, not America. -- Witold Baryluk JID: witold.baryluk // jabster.pl -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
