USe whois to get a list of dns servers

$ whois totalflood.com

   DNS.TOTALFLOOD.COM           12.47.198.108
   DNS2.TOTALFLOOD.COM          65.223.121.228
   NS3.INFLOW.NET               216.183.114.115
   NS4.INFLOW.NET               66.179.160.115

Then query each for the SOA record

$ dig @12.47.198.108 totalflood.com SOA

totalflood.com.         3600    IN      SOA     dns.totalflood.com. 
domainadmin.totalflood.com. 99 10800 900 604800 3600
                                           ^^
(in this case 99 is the serial number)

etc...
