A dive into DNS

Everyone kind of forgot about DNS. How does it work, how to claim it back and why?


This talk will show some data about DNS to see differences between TLD's, will show how the entire thing works and the current problems in some setups. Then show how to make our own authoritative DNS servers in a secure and redundant way to claim ownership of it and decentralise it from the big providers.

Network Engineer by day, Hacker at night. Did various (nasty) things with DNS in various situations (some better than others). I also authored 2 articles on RIPE labs about DNS (one of them implied tests that got evidently noticed on graphs of the FOSDEM network last year). I'm now also part of the FOSDEM NOC team.
