Note in your dig trace that the 60s TTL is for the CNAME record pointing www.intel.com to www.intel.com.edgesuite.net. Now edgesuite.net is an akamai service AFAIK. The purpose of keeping a very short TTL, as far as I see, is to prevent downstream DNS servers from caching it for a long time (obviously). This would typically be done if the record gets updated frequently... but hey, akamai is known to do weirdly interesting stuff! ~ViM -- Vipul Mathur vipul at linux-delhi.org _______________________________________________ ilugd mailinglist -- ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd Next Event: http://freed.in - February 22/23, 2008 Archives at: http://news.gmane.org/gmane.user-groups.linux.delhi http://www.mail-archive.com/ilugd@lists.linux-delhi.org/
