Really? We have hundreds of hosted web sites using a CNAME to the name of
the hosting server and it's always worked just fine.
I have no doubt that using an A record is preferred but when you have
hundreds of domains pointing at a server and then you change the IP address
of the server only having to change the A record for the CNAME is preferred
to having to edit hundreds of zone files. I've never seen the use of a
CNAME affect the ability to connect to a web server virtual and there are
plenty of popular web sites using CNAME's.
