What do you mean by "forwarding hosts"?

When I do nslookup on cobalt.vpopmail.org and on vpopmail.org I see good
dns for it:

<snip>
$ nslookup cobalt.vpopmail.org
Server:  ns1.ns-one.net
Address:  63.108.93.101

Non-authoritative answer:
Name:    cobalt.vpopmail.org
Address:  202.126.189.250

$ nslookup vpopmail.org
Server:  ns1.ns-one.net
Address:  63.108.93.101

Name:    vpopmail.org
Address:  202.126.189.12

$
</snip>

When I do lookups on the IP#s (reverse lookups) I get:

<snip>
$ nslookup 202.126.189.12
Server:  ns1.ns-one.net
Address:  63.108.93.101

*** ns1.ns-one.net can't find 202.126.189.12: No response from server
$ nslookup 202.126.189.250
Server:  ns1.ns-one.net
Address:  63.108.93.101

*** ns1.ns-one.net can't find 202.126.189.250: Non-existent host/domain
$
</snip>

Is that what you mean?  You can't do reverse DNS for your IP#s unless
the owner of the IP#s delegates the authority to you.
