The DNS has been around for a long time. Over the last 35 years, how the Internet and the DNS have been used (and abused) has changed.As a vital part of accessing services, it is critical that DNS isaccurate, available, and reliable.

But like all technology, the DNS must evolve. More widespread use of DNSSEC and split horizon, as well as new transports such as DoT and DoH, make best current practices very much a moving target. Tomake our lives even more complicated, lots of false or staleinformation about how to best run DNS services makes informedarchitecture decisions a continuous challenge.

This talk will cover some of the persistant bad information that we can’t seem to get rid of, as well as covering how more recentchanges have affected the DNS or will in the near future. Armedwith more accurate information, we can weigh all the tradeoffs andcome up with a design that meets our organizations' needs.
