Well, A6 is not DNAME; the only relation is that A6 needed DNAME in the reverse lookup direction. DNAME is quite useful in the forward lookup direction, particularly since synthesizing CNAMEs for older resolvers is part of the requirement. It allows moving of an entire subdomain wholesale from one parent to another without creating a flurry of CNAMEs. This helps even more if you have a wildcard subdomain in there. 8-) -- -- Todd Vierling <tv () duh org> <tv () pobox com>
