Ah, how many k/second?

> sometimes several times a minute

WTF?

We're talking 0.00003 thousand requests/second? Most apps do several DNS queries per minute. Otherwise every DNS update would require >1 minute to propagate. Slow DNS updates is a massive pain in the ass.

FWIW, ISP DNS servers and cheap home routers are both capable of caching DNS responses, updating the cache when they get a query for something that's about to expire, and serving thousands of queries per second.

> then they told me to take it up with my ISP and immediately closed the chat

This is the correct response. DNS is usually provided by the ISP via DHCP. If their server can't handle "several times a minute", the ISP would be at fault 100% of the time

My DNS service isn't having any problems, that's your imagination. Everything works. It's just filling up my quota. If "every app" is doing this, why does Netflix account for close to half of all DNS requests on all my devices?

I explained to them that I'm not even using ISP DNS. They still told me to talk to the ISP. Still think it was the correct response? It was obvious they didn't even know what DNS was, they were just slavishly following a script that said DNS resolving issues -> ISP. They didn't even grasp what I was reporting to them.
