Contrarily to dnsN.emarkmonitor.com, nsN.markmonitor.com replies to queries.
But the answer is still different from google servers :

% dig +short @ns1.google.com gmail.fr
173.194.66.17
173.194.66.18
173.194.66.83
173.194.66.19

% dig +short @ns1.markmonitor.com gmail.fr
72.14.253.83
64.233.161.83
64.233.171.83

Best regards.
