Is it possible to set a CNAME record for a toplevel domain like example.com?
My ISP says that it's only possible to use CNAME's for subdomains but I've read somewhere else that is should be possible even if not recommended.

A:
Not possible - this would conflict with the SOA- and NS-records at the domain root.
From RFC1912 section 2.4: "A CNAME record is not allowed to coexist with any other data."
