Why is Roon blasting my DNS server with requests?

This has been discussed before, but there hasn’t been a satisfactory answer:

Rock pounding the DNS

I see 1000’s of requests to the same url every few days, shouldn’t ROCK just cache it? [image]

Yes, and Roon certainly hammers the DNS servers hard… I’ve a Pi-hole on my network, and I just got notified that my Roon Core server has been rate limited to 1000 requests per minute… About 65% of all DNS requests on my network originate on the Roon server. metadata.roonlabs.net and imagecache.roonlabs.net get hit very hard when doing metadata or image updates. Those blue spikes are all by Roon Core updating metadata and image data… The last spike is just from a few minutes ago, when I saved s…

I’ve installed Pi-Hole on my Linux Roon Core server, so most of these requests are just local hits on Pi-Hole’s cache. In fact, in any 24 h period, about 80-85% of all DNS requests go to the cache, and near all of that is by the Roon Core. This traffic comes from metadata and image updates.

With these periodically massive numbers of DNS queries I wonder why Roon wouldn’t implement some sort of DNS caching on its core server, to reduce the impact on people’s networks and routers…
