Dynamic update of virtual hosting domains

Hello,

I am hosting a number of domains by means of DNS based hosting. The domain 
zones look identical:

$ORIGIN <domain>
@	soa  ns1.<hostingdomain>. ....

@	ns   ns1.<hostingdomain>.
@	ns   ns2.<hostingdomain>.

@	mx   10   mx1.<hostingdomain>.
@	mx   20   mx2.<hostingdomain>.

www	cname @

@	a    <IP of web server>


Sometimes I need to change <IP of web server> automatically, however enabling 
dynamic updates on all (currently 9) virtual host domains seems ugly. I know I 
can use the DNAME RR, but from my googling it seems that it is not favored in 
todays infrastructure. Is there a way to organize things in such a manner, so 
that the A record can point to a single place which can be then dynamically 
updated?

Thank you for any pointers.

Peter
