I updated our router over Christmas which is an Asus RT-N66U to the lastest firmware and also changed the DNS to 9.9.9.9.
All was fine afterwards, at least I had no issues, and no complaints from staff that were in the following Friday morning.
This week our office workers have been complaining of slow internet, and it seems to be DNS related so I changed the DNS back to Googles 8.8.8.8 and 8.8.4.4.
But this doesn't seem to have made any difference, in the morning they don't appear to have any internet so have been power cycling the modem and router, but I can see from both MDWS & TB ping graph we have no connection issues in that respect. I haven't noticed any problems either, apart from some very rare slow page loads - again which appear to be DNS related.
My knowledge is very limited as is my time, I tried some pings this morning to get some IP addresses of websites, but the results seem a bit weird.
If I ping the bbc.co.uk I get a IP address of 151.101.0.81 and respectable ping times of around 19ms. But if I enter 151.101.0.81 into my browser (chrome) I instantly get the following error.
Fastly error: unknown domain: 151.101.0.81. Please check that this domain has been added to a service.
Details: cache-lcy19244-LCY
If I ping kitz.co.uk I get 185.24.98.37 and 21ms pings, but if I enter the IP address in the browser I get an error message saying sorry with the address of
http://185.24.98.37/cgi-sys/defaultwebpage.cgiPinging itv.com just times out, yet entering itv.com in my browser works, same for ebay.co.uk
Running trace cert also has more weirdness

Not sure whether it's because I've not got a clue what I'm doing, or something is amiss somewhere.
Any idea's before I tell them they need to get someone else involved, or should I be contacting our ISP which is Plus Net Business?
