One could get even more unlucky: $ for f in $(dig +short ns ca. | sort) ; do echo $f:$(dig +noall +auth a doesnotexist-234234234.ca @$f) ; done any.ca-servers.ca.:ca. 3600 IN SOA prdpublish04.cira.ca. admin-dns.cira.ca. 2011171330 1800 900 3456000 3600 c.ca-servers.ca.:ca. 3600 IN SOA prdpublish04.cira.ca. admin-dns.cira.ca. 2011171330 1800 900 3456000 3600 j.ca-servers.ca.:ca. 3600 IN SOA prdpublish04.cira.ca. admin-dns.cira.ca. 2011171330 1800 900 3456000 3600 x.ca-servers.ca.:ca. 86400 IN SOA prdpublish04.cira.ca. admin-dns.cira.ca. 2011171330 1800 900 3456000 3600 1 of the 4 NSes (as seen from where I am) advertises a full day!
