I don't know much about DNS but ... how is this possible. How can the 
reverse be in the DNS but not the name?

But what I don't understand is where the name ns.tokyo-av-land.com 
coming from? Is some DNS server somewhere sending wrong (outdated) 
information?

If I can figure out why a reverse lookup of my ip gives the wrong FQDN 
then maybe I can get this fixed?
