"IP" blockage

When I attempt to log into and IP Address that has "Ad" in front of it, I get the following error:

"www.googleadservices.com’s server IP address could not be found."

The only thing I can find on this subject leads me to a "problem with NORTON." Does anyone know how to get rid of this problem?  It is very frustrating!

Hello THEOJ. I get the same 404 error on my side with both Edge and Opera GX browsers. That represents there is an issue with the server that is being connected to. I get nothing from Norton or its browser extensions that state anything is being blocked. IMA that I do not have any VPN enabled as well.
