In this talk Kyle will cover the basics of how DNS (Domain Name System) works. The talk will include a short history of the service, how it works today, and a step-by-step walk-through of what happens between entering a domain into a web browser and getting back an IP address. Also covered is how you could use this new-found knowledge to take down the Internet. Specific implementations of DNS (BIND, djbdns, PowerDNS) will not be covered.
