  I am not sure what you mean by this statement.  None the less, that IANA
Does not control the gTLD's that are on the A-M Root servers.  That is
done and managed by NSI currently.  The IANA recommends to NSI
what gTLD's and other types of TLD's should be entered onto the 13 legacy
Root servers.

  WWW.CYBER.COM.AU does not resolve from the Internic/NSI.  And
COM.AU is not a Legacy Root known zone.  SO you statement here is essentially
False.  If you doubt this, than go to and do a whois on either
CYBER.COM.AU or .COM.AU  And you get a return result of "Not Found".
So these zones are only known to NAME SERVERS in the Australian area
and possibly some in the us that recognize .COM.AU as a zone on their
Name servers.

  The term "Rogue" is a bit extreme in this context.  But that is of little
here.  .AU.COM is a known zone back to the Legacy Root servers.  And
.COM.AU is not.  And that is a significant point.
