Hello,
I am observing a high number of entries in named.stats:
502803 IPv6 NS address fetch failed
My network does not support IPv6.
Apart from using listen-on-v6 { none; };, is there a way in BIND to prevent or control these IPv6-related NS address resolution attempts?
My environment:

  *   BIND9.18S
  *   Redhat9.6
Any guidance would be appreciated.
