a URL forwarder

My DNS provider says the following in their FAQ. I thought that adding a
CNAME for "yourdomain.com" would redirect all requests, including URL, mail
and FTP. So why do they say this?

Why can't I add a URL forwarder for "yourdomain.com"?

URL Forwarding needs a zone record pointing to our redirect server
(redirect.public-dns.com). The appropriate record would be a CNAME, like:
yourdomain.com. CNAME redirect.public-dns.org.

The problems lies in the limits of dns zones. When you add a zone, like
"yourdomain.com", there MUST be an A record for "yourdomain.com".
CNAME records are not allowed to be added if a duplicate A record exists.

So, we're unable to provide a URL forwarder for the base record for your
zone.

You can, however, add as many subdomain URL forwarder records as you like
(ex. [url]www.yourdomain.com[/url], ftp.yourdomain.com, mysite.yourdomain.com, etc).

A CNAME record cannot coexist with any other records for the same name.
A delegated domain name is required to have NS and SOA records, so it
can't also have a CNAME record.

What you can do is look up the address of redirect.public-dns.org, and
enter an A record:

yourdoain.com. A <address>

Technically, one could put the CNAME in the .COM nameserver
instead of NS and SOA, but I don't know that anyone does that.
