Hello there friends, please explain me how it is with custom dns, adguard for example. I know with standard setttings my isp see everything, but if i will use some encrypted dns what they will see exactly? I know one thing - if i visit for example 9gag they will see that, but if i click memes category on that site they will know i clicked on that category or not? I also know if i want full privacy I must use tor or / with vpn but this time I asking about this situation. Thank you so so much.
A good chunk of the web uses CDNs (content delivery networks) which puts a bunch sites behind the same IP and those gateways rely on SNI to figure out which site to send to the requestor.
