>From Qwest's network in downtown Chicago, Illinois, USA: 0.ntp-pool-test.logidac.com -> 67.128.71.75 (US, CA, Los Angeles, 72 ms) 1.ntp-pool-test.logidac.com -> 65.102.104.139 (US, FL, Delray Beach, 102ms) 2.ntp-pool-test.logidac.com -> 71.32.26.51 (US, ND, Fargo, 88ms) 3.ntp-pool-test.logidac.com -> 216.136.10.198 (US, MI, Bay City, 87ms) 4.ntp-pool-test.logidac.com -> 208.44.169.14 (US, UT, Grantsville, TIMED OUT)
It appears the BGP-based scheme works better on Qwest than it does on Sprint. At least all of the returned servers are in the continental US. This is probably because Qwest is a US-focused ISP, whereas Sprint has more global reach). That said, I know there are much closer servers in us.pool.ntp.org. There are certainly at least a few in the Chicago area. IP-to-coordinates databases such as IP2Location are available for $350 per year per server. http://www.ip2location.biz/IP-COUNTRY-REGION-CITY-LATITUDE-LONGITUDE.HTM However, I would think this would be an easy database to build in an open-source fashion. It would certainly be very useful to a lot of open-source projects. I think that a front-page Slashdot article would generate enough volunteers to capture location data for just about every ISP in the US and Europe. _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
