Apr 14, 2020 · Your computers, phones, and other devices normally use the Domain Name System (DNS) server with which the router is configured. Unfortunately, this is often the one provided by your Internet Service Provider (ISP). These lack privacy features and also might be slower than some alternatives. DNS Is Not Private (Without DoH) The computer sends the domain name as a DNS request to the user's Internet Service Provider (ISP). The ISP determines if it has the IP address associated with that name; If not, the ISP forwards the request to other providers in an effort to located the DNS record that contains the data.
