There is no harm if they do. The problem is the root servers themselves being unable to put out full sets of A records for the NS'es for "." without overflow. If your local name server has all of it, there is likely no harm. We especially don't want people doing TCP based queries against the roots. We've already been told, by the way, that older versions of BIND won't cache the AAAA/A6 records at all. Perry
