If you knew an ARPANET computer's name, you would simply look up its IP address in the HOSTS file.

System administrators would download hosts.txt periodically.

With only a few computers linked to ARPANET, the US Defense Department's Network Information Center maintained a file named HOSTS.TXT - a master list of each computer's address and its hostname. How is that possible?īack in the days when the Internet was young and called ARPANET, there was devised a naming system that mapped a computer's IP address to a unique ASCII-based identifier. Surprisingly, DNS-level blocking is the oldest known approach to ad blocking. You might not notice the difference between them, but some old devices may misinterpret REFUSED and try to use a fallback DNS server. Other options are responding with NXDOMAIN (which means that the domain does not exist) or REFUSED (which means that the server refused to process the query). So, the app simply cannot connect to this address and we have the desired result - the connection is prevented.Īn example of using a DNS server to block access to a domain When your device sends a "bad" request, be it an ad or a tracker, a DNS server responds with the 0.0.0.0 IP address for a blocked domain. Usually, it is done by using the DNS Sinkholing technique, which means handing out non-routable addresses for blocked domains. There are also DNS servers that provide DNS-level blocking. Your device always uses some DNS server to obtain IP addresses of the domain name apps want to navigate to. And a regular DNS resolver simply returns the IP address of the requested domain. So each time you go to a website, your browser sends a DNS query to a DNS server (which is usually provided by your Internet Service Provider) to figure out the IP address of the website. You can think of DNS as the "address book" of the Internet. Just to refresh your knowledge, DNS stands for "Domain name system", and its purpose is to translate websites' names into something browsers can understand, i.e. Why? Because DNS is the answer! What DNS-level blocking is Then buckle up and get ready for a fascinating journey through the past, present, and future of DNS filtering. But what if you want to widen this "window" and have it all? It provides just a tiny window into the "better Internet" without aggressive and intrusive banners vying for your attention. Given that ads and ad trackers are everywhere the Internet is, a browser-based ad blocker seems to be not enough.
