As an exercise for the reader, how would you handle migrating your DNS server(s) from one IP address (or one subnet) to another, using similar techniques? Do you need to talk to someone outside your organization, or can you do it all in-house? Are you sure of your answer to that last question? How would you find out for sure... :) A Google T-shirt(*) to the person who comes up with the best / most complete answer(+).
Since you said "similar techniques" I'll follow your lead. :-) 1. Examine your current SOA (Start of Authority) record and NS records, determine their TTLs, we'll say 2 weeks. 2. At least one current-TTL-interval (2 weeks) before you intend to make the change, update the TTLs for the SOA and NS to be very low, for example 2-4 hours. 3: Set up the new DNS servers with the new information then 'throw the switch' by changing the whois record. 4: Establish that everything is working as expected, perhaps wait 1 day to be sure. 5: Make a final DNS update to return the TTLs to their previous long / stable values. I believe that would cover it, right? :-) Cheers, Tanner -- Tanner Lovelace clubjuggler at gmail dot com http://wtl.wayfarer.org/ (fieldless) In fess two roundels in pale, a billet fesswise and an increscent, all sable. -- TriLUG mailing list : http://www.trilug.org/mailman/listinfo/trilug TriLUG Organizational FAQ : http://trilug.org/faq/ TriLUG Member Services FAQ : http://members.trilug.org/services_faq/
