He's been a bit busy lately. :) The short answer, Chris, is don't do
it yourself unless you're confident you know what you're doing.
Presuming of course that your business depends on it, that is. You're
not going to be able to modify the dyndns NS records, as far as I'm
aware. Even if you could, that would only buy you the ability to
survive a catastrophic dyndns failure, it wouldn't let you update the
records in any more convenient fashion. I'd also suggest that having
dyndns host your DNS for you isn't the most reliable thing for your
uptime either, honestly.
I'd suggest that if you want to have direct and relatively immediate
control over the records from a BIND server, yet still have sufficient
reliability, you should setup a local BIND server on a static IP on a
link you control. This link does not have to be 100% reliable, although
it wouldn't hurt. Then pay someone to do secondary DNS service for
you. Your ISP, various other folks on the Internet, etc may be able to
do this for you. It shouldn't cost much, on the order of a few bucks a
month, tops. They should provide you with 2-4 servers which will slave
to your primary server, essentially scraping the data from it when ever
you update it (and periodically to ensure things are in sync), and serve
it from a reliable location.
Note that this gives you more power. With great power, comes great...
yeah you know the schpeil. You'll have the complete ability to quickly
and easily take your company's website off line for long periods of time
(think, days, weeks) with a bad misconfiguration.
If you have more questions about this, feel free to ask,
