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!

It's worth putting a single caching DNS resolver in the network for everything to use, but I don't see an advantage on a single device.

The first DNS query will take as long as it takes, then the tiny few mSec it saves on subsequent "1st" queries for everyone else makes the difference

Also, but blocklists in that DNS Resolver and you'll improve your entire network from trying to lookup crazy sites.

Thank you, I see the advantages of a network approach. In my case it's just two laptops in my network, and I'm also thinking of the case when I'm using the laptop in some other networks.

If you only have 2 laptops and they are both going to search externsl DNS, then there's probably still no point in local DNS

To refer to each other - presuming they have static IPs - just update their /etc/hosts with the other device's IP address and that will speed things up
