CNAME or A record?

[feralert]

Thanks Jeff,

But I really only wrote that as an example :) . The real question is
what is best or what is recommended, two A RR (one for domain, one for
www) or a single A RR for domain and a CNAME RR for www, is one way
better than the other or can I choose either way?

Cheers!,
Fred.
