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...
