Now that you tell me, I remember reading something about that. I have
to get a bigger brain to remember all that stuff ;-)

I thought that CNAME were used (at least partly) to help
administration. That is : my web server is called "cobalt.genam.ch" and
all the domain hosted are CNAMEs pointing to "cobalt.genam.ch" so when I
change the IP of cobalt.genam.ch (or if I change the web server to
another host) I have only one file to edit. It seems I was at least
partly wrong.
Is there a better way to achieve this easy administration ? Or do I
definitly have to treat all zones separatly ?

PS : the RFC 1034 was a very interseting reading, but a bit outdated
(still speaks about MG and MD records, not MX). But I think I am going
to read more of those RFC, just need some time.
