Re: DNS changes

[Mark <mark@bish.net>]

Ok, today is a little better.

My IP is changing for bish.net and I don't want to wait forever for it to
update.  I can just take bish.net down, then update the record over at
Internic so that DNS for bish.net points to the new address, then wait for
the changes to propagate.  This takes about a week and I'm wondering if
someone might have a better idea that might be quicker.
