Profile

There's been a lot of talk recently about "apps doing DNS", where every application on your computer could be talking to it's own DNS resolver. This is because of the somewhat recent 2018 protocol, DNS queries over HTTPS (https://tools.ietf.org/html/rfc8484). Turns out that with DoH, not only can every application do it's own DNS -- essentially every website you visit could be using whatever DoH resolver they want when fetching external resources that require a DNS lookup. That means stylesheets, scripts, images, etc, call all be loaded from whatever domain without going through your default DNS resolver. For a lot of people, that might be disturbing. For others, that might be super useful.
