Using NGINX as a DoT or DoH Gateway
Using NGINX as a DoT or DoH Gateway There’s a lot of talk surrounding the Domain Name System (DNS) at the moment, with massive changes being proposed for the 36-year-old protocol. The Internet’s name service, which has its origins in ARPANET, has never had any backward compatible breakages since its inception.

In this post I look at two emerging technologies for securing DNS, DNS over TLS (DoT) and DNS over HTTPS (DoH), and show how to implement them using NGINX Open Source and NGINX Plus. The History of DNS DNS was the second attempt at creating a naming service for the Advanced Research Project Agency’s (ARPA) early Internet, the first being the Internet Name Server protocol published by John Postel in 1979 as IEN-116.
