Spurious "No NS records" for fox.com #9

Closed bortzmeyer closed 8 years ago

bortzmeyer commented 8 years ago

% check-soa -i fox.com No NS records for "fox.com.". It is probably a domain but not a zone

But fox.com does have proper NS. May be the bug is because of the unusual size of the NS RRset?

% dig +short NS fox.com

Note that fox.com is broken for other reasons so it does not work completely:
