	Myself, I wouldn't worry too much about this issue.  Yes, if you 
go to change the IP address of the machine, this means that you'll 
need to make the same change in multiple places.

	Use the same IP address for multiple records, as has been shown 
here.  It really is the only way to get this to work.  If you want to 
minimize the number of different records that share the same IP 
address, then use CNAMEs for things like "mail.yourdomain.com", 
"www.yourdomain.com", etc... and use IP addresses for the apex of 
"yourdomain.com" itself and "ns1.yourdomain.com".
