I have a node x connected wired to a tplink mesh network (it is wired to one of the nodes which then uses the 6Hz backhaul to main node. I have noticed that it seems to have made 117000 dns requests for a38x1mwq2evzdd-ats.iot.us-east-1.amazonaws.com in the last 24 hours and continues to do so ti. The dns server pi-hole is responding to these requests with the correct ip address and I can ping that amazon address. Why is ithe bluesound doing this and how do I stop it?

  Ok I think I've stopped it.
  
  I had an old no longer available network share in my library (so non of the library was actually available i.e. ithe diagnostics page didn't show the mounted share but the library had lots of entries). I removed this and reindexed the library (so there was no library) and it has stopped doing it. I don't use the blueos library anyway as I use roon so probably for the best.

  I'd seen this post. It doesn't tell me how to fix it though and is a different network layout.  I chose not to pollute that posters thread with my issues.
  
  1. No other devices on my network are making excessive dns requests
  2. The bluesound is wired and has an fixed local ip address. The tplink will use it's backhaul but the bluesound has nothing to do with that. It should just see a wired connection.
  3. the dns server is replying to the requests with the correct ip address.
  
  
  So the questions remain in fact there is more.
  
  1. Why is it doing this?
  2. What does it need to keep contacting the internet for when it isn't even being used?
  3. How do I stop it?
  
  I'll try flushing all the dns caches but this is very poor behaviour from a network device

  Do you have "statistics collection" (Help - Diagnostics) turned on?

  Ok, then you should send a support request.

  I still think this sort of behaviour is quite poor and should be fixed though. Repeatedly doing the same dns request when the request is being correctly satisfied does not seem like good coding maybe cache the result and only do a new request if it is stale?
