Well, here's what I saw:

On the 5th or 6th, I changed all the domains' TTLs to 300 seconds.

On the night of the 8th, I moved my network to the new IP block.

On the 9th, which is 3-4 days after I'd changed all the TTLs, some of the domains took as long as 24 hours to pick up the changed IP.

Good; so I'm going to try this again on the 15th and keep my fingers crossed. A wrong subnet mask made the whole thing a complete mess…

Thanks,

Bob
