What's everyone's favourite federated, distributed, eventually consistent, caching key-value store? That's right: DNS.

This live demo will answer such questions as Why DNS?, Why DNSSEC?, Why Punycode?, Why did a minor Chrome feature DDOS the root servers?, and Aren't 5 TLDs enough?

Come and marvel at how DNS has survived and adapted over the last 40 years. Yes, 40.

He has worked over the years on automated telephony, Google Production SRE, Mainframe Linux, and more recently for various financial firms, all of which used DNS. He cannot juggle.
