Original poster in our forum agrees your description. But he
also points out that the problem doesn't occur with BIND9.
Though we understand that to fix lame delegation is proper
way, I guess this is a disadvantage to deploy unbound. Any
plan to rescue?
For example, if you find that ns-tk022.ocn.ad.jp is lame
delegated, fetch A's of ns.visualjapan.co.jp, and
continue to work.
Thanks in advance
