2 times, one error with 1 ddns host, i have 14 ddns hosts.
ping6 martine.ddnss.org give unknown host back.
in named.log I see the hostname with added local domain.
this happens only at the ipv6/AAAA-record, only by this host,
not at the ipv4/A-record.
when I restart named is all ok.
Is that a bind-bug?
