I realise that keeping the old IP functional for some time is important for all the static configurations. But does it matter if a dynamic list is updated "real time" without much advance warning ?
3 weeks is not a lot of "advance warning".
3 weeks is plenty for a service that in 6 months you may see degraded to 12/13 capacity if you haven't properly maintained it AND it is used for recursive service. (trusting a referral from a root or sub-root delegation to the root is crazy!). I could only wish my automobile would notify me 6 months of its impending failure should I take no action... Oh, and you can just download the root zone from ftp://ftp.internic.net/domain/root.zone ... - Jared
