I specifically do NOT do that.  I always use dns servers that are both 
off-network and neither our primary or secondaries to resolve dns because I 
want to know about any dns-propogation problems BEFORE my customers tell me 
about them.

This should NEVER be a problem because all dns servers SHOULD honor 
time-to-live.  If they do, then a short time-to-live should solve the 
propogation problem.  That it doesn't is only because providers (like AOL 
as a good example of a bad habit) dishonor ttl.  (Time-Warner is merging 
with AOL.  Yucch!)

So my name-based hosts' owners can find their sites before DNS propogates, 
and so that users with really old browsers can do the same, here's what I 
recommend to my dns customers (we run a dns business under <ns-one.net>):

Always run one IP-based site for the IP.  That site should go to a page 
with hard links on it to all name-based sites.  Those links should be 
symbolic directory links inside the directory pointed to by the IP-based 
site.  This will always work.

The rest of the sites should be name-based.

It's considered bad manners to point to someone else's dns server without 
permission.  But there are several options if you don't have any offnetwork 
dns servers that are neither primary nor secondary servers for your 
site.  Though we normally charge for people to use our servers, I'll allow 
anyone on this list to use one of our servers on a temporary basis FOR 
INDIVIDUAL USE if and as required.  I ask only that you write me at 
<dns-request@xxxxxxxxxx> and let me know.  Try to write at least a day in 
advance; I'll write back and let you know which of our servers to use.  If 
you have a fulltime need for a private-branded server, let me know; we have 
virtual servers and actual servers available (can't use the word "real" in 
connection with "servers"; it's trademarked <frown>) with good connectivity.
