As it's a dynamic IP address the BQM is monitoring the hostname of my PfSense, which has been the case for months. I've confirmed that the IP address has updated correctly in PfSense, with the same IP address as my DNS provider is displaying. So as far as I can tell the BQM is correct but am happy to have any issues pointed out.
I agree it looks strangely clean. The VM engineers told me there had been a lot of complaints about noise on the network which you can see on previous BQMs, and they were replacing older cable and components to resolve the issue. As long as it's stable I'll be happy....
