[QUOTE="ForgottenSeer 92963, post: 959233"] Adblocking on DNS level can only block resolve requests (find an IP adres for this URL domain), it can't modify CSS styling, can't strip/redirect elements out of HTML and can't inject javascript. DNS level adblocking really is no alternative for content filtering with extensions. DNS adblocking is using a mechanism to block bad URL's used for malware, phising, command & control servers. The reverse is also true, malware blocking using local URL blocklists is also silly (covers at best 1 percent of the blacklist used at DNS and Antivirus Companies have in the cloud). Malware URL blocking with local URL blocklist in your adblocker is like using a speed boat for world wide cargo transport. When a DNS blocks a request to a bad URL, the intended use is to break the (malware) delivery chain. It is all or nothing. It is a sledge hammer compared to the tweezers of adblock rules Just open Easylist filter and search for @@ (allow exception) and 'important' (giving priority to a block rule over an allow rule) or 'third-party' (block as third-party, allow first-party). And these three examples are the easy ones, this are not the cosmetic rules or advanced CSS, HTML and javascript(let) rules I mentioned earlier. PS I am using DNS level blocking of advertisement for my android TV box (because that is the best I get for free on that device). [/QUOTE]
