I mean, how can the determine it's a Comcast DNS server configured on my network? I might be a Comcast customer w/ a custom DNS server configured. If it's a fixed IP check, I suppose that list is in the browser.
- TheSwordsman 6y agoWhat makes you think they are doing that? To jlgaddis's point, they are likely checking what IP address you are coming from over the public Internet. They can see who operates it, and knows that it's Comcast. Then they change the options in your browser.
