My Own DNS Server at Home – Part 1: IPv4

news.ycombinator.com Jan Wildeboer 2025-10-08 22:08:49

“It’s always DNS” is a famous meme among network people. Name resolution is technically quite simple. It’s “just” translating a hostname like jan.wildeboer.net to an IP address. What could possibly go wrong? I am a radical optimist and detail-obsessed knowledge collector, so I decided to find out. As part of my goal to make my home network a little island of Digital Sovereignty, meaning that everything at home should JustWork™, even with no working internet connection, a DNS server is needed.

Blast from the past: Facit A2400 terminal

news.ycombinator.com Jan-Piet Mens 2025-10-27 21:53:38

The year is (roughly) 1989, and we have a small office with some Unix computers and a handful of Facit A2400 terminals connected to them. What we love most about these terminals is they are positive terminals with black text on a white background. We “grew up” with green on black and, later at Nixdorf Computer AG, with amber on black. Young readers might be surprised we used to get printed manuals with our terminals (and computers); don’t forget, the Web didn’t exist then, and “download the man

Configuring Split Horizon DNS with Pi-Hole and Tailscale

news.ycombinator.com Ben Tasker 2026-01-26 09:08:54

I've long had some form of VPN for my devices to use when I'm out and about. Although I used to run OpenVPN, I moved to Tailscale a little while back. Tailscale builds a mesh network using Wireguard protocol and so is able to connect and run quite a bit faster than OpenVPN. Side note: for those wondering, Tailscale is Canadian and can't see the content of connections (although if you're worried about this it's also possible to self-host using Headscale). Although the tailnet has been up for s
