Hi everyone, In the spring I started some experiments to figure out how accurate the "GeoIP information of DNS server" vs "GeoIP information of client IP" is. I made a little tool that can tell you what the IP address of your DNS server (as seen by the pool dns server) is. You can try it at http://ip.bitnames.com/
As you might know the DNS servers for pool.ntp.org are using the MaxMind databases to try getting the client a "local" server (by country). I noticed that for server IP space it's not terribly accurate (or maybe I was just unlucky with the 4 or 5 I tried tonight). The development server[1] for the experiment can tell you what GeoIP information it got for your client ip, the IP of your DNS server and for the EDNS-SUBNET information (if you use Google DNS or OpenDNS). You can try that by running: curl -Ls http://www.mapper.ntppool.org/none; sleep 1; curl -s http://mist.askask.com/api/v1/myip If you see incorrect information for some of the IP addresses, please tell MaxMind: http://www.maxmind.com/en/correction Ask [1] Whereby "server" I mean "laptop". _______________________________________________ pool mailing list [email protected] http://lists.ntp.org/listinfo/pool
