Bad idea, the information in the DNS itself ("dig NS totalflood.com") is
typically more recent and more reliable.

This can be automated with check_soa (in Liu and Albitz' book, see
http://examples.oreilly.com/dns4/ for the source code):

% check_soa totalflood.com
ns3.inflow.net has serial number 99
dns.totalflood.com has serial number 99
dns2.totalflood.com has serial number 99
ns4.inflow.net has serial number 99
