DNS errors flooding the system 24.7.8

[lshantz]

I started a fresh install, since every update seemed to cause the system to go down. I suspect legacy things were clashing. Anyhow now there are a couple of issues that I do not understand.

This is one issue. Yet, if I ping those addresses they resolve and answer back just fine. I saw that a device was not using these servers, but going to an alternate. I wondered why. This is what I see.

The other issue, I'm guessing related is:

It appears that a device is sending some sort of HTML file? So far I have not found which device is blasting this. I guess it IS rejecting the request, but as much as it is hammering the system, I would think this could impact performance.

Any suggestions welcomed. Thanks in advance.
