Your Internet Service Provider [ISP] is watching everywhere you go on the internet. They are harvesting that information and selling it to the highest bidder. The easiest way for them to do this is to watch the DNS – Domain Name Service – requests coming from your network. DNS is the Internet Phone Book and every time you visit a website, or play a video or anything – from your phone over WiFi or from your computer, your computer or phone looks up the IP address – a number – based on the Domain Name – a text string. And DNS is the protocol that does this. Normal DNS is completely in the clear. That is, it is not “Encrypted” in any way. Once you reach a website, to purchase something or look at your Facebook page or whatever, almost all sites are “Encrypted” so that nobody can eavesdrop on what you are doing. This all happened a few years ago after folks were sniffing everyone’s Facebook pages in coffee shops and libraries. But I digress.
DNS has only just recently been fixed. And up until now, and until you fix your network, as I outline below, your ISP is sniffing all your DNS requests, because they can. This means they know everyplace you go on the network.
