Hello Janis!

 O.K. it is clear the now there is no automatic expansiom from org to org.net
 I will not comment on the: mail is handled by 0 0
 It may be a response to MX not being declared, that is o.k. if the host is
 the mailserver for his own hostname.

 I will not endorse that, the one is a domain name the other most probably
 a host name. There is a custom to do what you suggest.

 I have been looking at some random hostnames in no-ip-org that I found in the
 nodelist:

$ host oal-fido.no-ip.org.net
oal-fido.no-ip.org.net has address 23.21.224.150

$ host bbsplanb.no-ip.org
bbsplanb.no-ip.org has address 77.179.73.155

$ host bbsplanb.no-ip.org.net
bbsplanb.no-ip.org.net has address 23.21.224.150

$ host fidocl.no-ip.org
Host fidocl.no-ip.org not found: 3(NXDOMAIN)

$ host fidocl.no-ip.org.net
fidocl.no-ip.org.net has address 23.21.224.150

$ host no-ip.org.net
no-ip.org.net has address 23.21.224.150

$ host anyname.org.net
anyname.org.net has address 23.21.224.150

$ host org.net
org.net has address 23.21.224.150

So it is clear that someone who has org.net as domainname has only one
host and has setup a wildcard entry that always directs to that host.

The DNS services are hosted on the dns servers at digimedia.com
digimedia.com can be found in whois.

The same happens is try to resolve the 26 fidonet.net addresses still in the
nodelist.

So it all seems coincidence.

The only question that remains is where did the expansion from org. to org.net
 come from.

It also happened in Oktober when I sent you a small list.
The expamsion of org to org.net also occurred there together with the response 
of 23.21.244.150

 Weird science.
