after we moved a server to a new location, prepared the change hours ago by lower the TTL from 1 hour to 5 minutes and find out that openDNS was one of few dns-servers which answered with the old IP *some months* later i would not recommend anybody using it because such things *must not happen - never* -------- Original-Nachricht -------- Betreff: WRONG REPSONSES Datum: Thu, 16 Feb 2012 15:16:42 +0100 Von: Reindl Harald <h.rei...@thelounge.net> An: cont...@opendns.com good day can you explain me why a server which was migrated Oct 2011 to a new location is still with the old IP in your nameservers? OLD: 193.104.1.241 CURRENT: 91.118.73.17 we are SOA for this zone and had a TTL of 5 Minutes some hours before migration and of 1 hour months before it was done!
