This past Tuesday I hosted a DNS training seminar for all the employees at Sago. It went over great! The curriculum involved:

• The difference between Caching and Authoritative DNS
• All the different types of DNS Records
• How to use dig and how to interpret it
• How to troubleshoot dns problems
• Secret DNS Tricks!

I recorded the AUDIO (sorry the audio sucks) and the BASH history for those poor souls who want to listen to me drone on for an hour about dns…. :)
