From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Unbound as DNS resolver on a Linux laptop: tips/experiences? (lemmy.ca)

[Edit: this question came out of my confusion. I thought Unbound could somehow substitute DNS servers (like CloudFlare), but it can't. Apologies for my ignorance.]

I've often heard about Unbound, and the possibility of using it as a DNS resolver on my laptop. So, to be clear, not as a DNS resolver in a local network; just in a single machine, also because I'd like to use it no matter where I bring my laptop.

The instructions given in the second link above seem quite complete. Does anyone here have other tips or experiences to share? I'm with Ubuntu on a Thinkpad.

Cheers!

You may already have a local dns caching mechanism on your computer. I think by default Ubuntu uses systemd-resolved (it does on my desktops anyway). If you check dig it’ll show lookups coming from 127.0.0.53. With that in place, your local machine is caching lookup results and anything it doesn’t know, it’s forwarding to the network’s resolver (which it gets via dhcp, usually).

Thank you for this comment. So Unbound does only DNS caching, without really resolving? I think I've completely misunderstood its purpose.

Unbound can query the root dns servers, but it’s also commonly used as a recursive resolver, which just uses a server upstream, similar to systemd-resolved. I use unbound network-wide, but I have it querying 9.9.9.9 to take advantage of their filtering.

Now I understand, thank you for the explanation!
