Poll: Do you host and operate your own authoritative DNS server?

I am curious of two things.

- How many self host their own authoritative DNS servers these days, meaning the NS records for domains you rent point to your own self hosted DNS daemons.

- Of those that host their own, do you occasionally watch the traffic hitting your servers and observe how bot traffic has evolved and what information open resolvers are sharing with you? edns0 client subnet, etc...

I am just curious what others see. I've had some of the same bots hitting me for decades and every year the information I see evolves a little bit due to how open resolvers have also evolved.
