The number of already IPv6 capable servers in the pool was discussed some time ago. Through a quick search, there are _at_least_ 13 IPv6 capable machines listed in the pool DNS as of about 10 minutes ago. (Obviously this could go up, or down, depending on the zone contents at any given time.)
Method: * Query every *.pool.ntp.org zone (as published in the pool statistics) * Query every returned IP for a PTR record * Query every valid domain name returned for AAAA records This obviously only works for systems with coherent forward/reverse DNS information and which use the same name for IPv4 and IPv6. Notably this excludes many DSL/Cable/Dial-up users. (Potentially a large portion of European IPv6 capable hosts.) Actual Command Line: cat poolzones|xargs -l1 host|grep -v ' not found: '|cut -f 4 -d ' '|sort|uniq|xargs -l1 host|grep ' domain name pointer '|cut -d ' ' -f 5|sort|uniq|xargs -l1 host -t AAAA|grep ' has IPv6 address '|tee ntp.ipv6.domains Resulting IPv6 Servers: a.ntp.br has IPv6 address 2001:12ff::8 bart.nexellent.net has IPv6 address 2001:4168:3::2 bema.one.pl has IPv6 address 2001:470:9971::4 cripps.orangesquash.org.uk has IPv6 address 2001:ba8:0:1f1:216:3eff:fe14:af00 dedi.drazzib.com has IPv6 address 2a01:e0b:1:12:240:63ff:fee4:6bc6 mail.pananix.com has IPv6 address 2001:5c0:9168::4 mirror.dedicatedservers.net.au has IPv6 address 2403:b800:1004:3::2 my1.doubleukay.com has IPv6 address 2001:c18:405::1 palmers.nobody.at has IPv6 address 2001:858:2:4:216:76ff:fe6b:d508 qbert.thatfleminggent.com has IPv6 address 2403:b800:1102:1::3 roma.coe.ufrj.br has IPv6 address 2001:12f0:4c1:6642::65 siim.ut.ee has IPv6 address 2001:bb8:2002:500:211:25ff:fe8f:7d64 station.mars.org has IPv6 address 2002:4706:bd56::1 In this query, there were 243 unique IPv4 results returned. Roughly 5.35% of the returned systems were IPv6 capable. DNS Load: This resulted in 663 DNS queries totaling 44120/55860 bytes out/in. Cheers, Kevin Bralten ---- After writing the above, I've rerun the query and come up with 12 IPv6 hosts, 9 of which are not represented in the previous query. _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
