observed.

$ for i in $(jot 20)
  do dig +noall +answer version.bind ch txt @pri.authdns.ripe.net.
  done | sort | uniq -c
   4 version.bind.              0       CH      TXT     "9.10.1-P1"
   8 version.bind.              0       CH      TXT     "Knot DNS 1.6.0"
   8 version.bind.              0       CH      TXT     "NSD 4.1.0"
