How to use same CNAME label for MX
You don't. You use ALIAS and MX for single root domain.
Cloudflare for Families DNS resolver and miscategorisation
today iain learned: How to report a miscategorisation of a site/domain in the Cloudflare for Families DNS resolver service.
Tabell over lovlige tegn for IDN i .no-domenet
Tabellen i «Generelle krav til domenenavnet - hva kan det søkes om?» er litt underlig formatert når den er satt i to liksom-kolonner. Jeg kunne tenkt meg at den ble formatert mer på følgende vis: Bokstav Navn på bokstav Unicode áa med akutt aksent 0x00E1 àa med gravis-aksent 0x00E0 äa med omlyd 0x00E4 čc med...

Moving Away From Cloudflare
A few weeks ago, after going to FOSDEM, I finally decided to move away from Cloudflare. That’s something that has been on my mind for quite a while, but I guess the law of inertia was keeping me from doing it. Today I want to show how simple it can be.
Custom DNS and TLS for my tailnet
this is mainly documentation for myself in future lol -- from 18/2/26 but i didnt post it lol
DNS in '26 for privacy and speeed
2026 is here, and it is time to begin technical writing on a regular basis; the complete opposite of the "LLM-ification" of the interweb.
Network-wide bullshit-blocking setup with Blocky and Tailscale
I will use an Orange Pi 5 Plus, but any device, including single board computers, should work, as long as they can run the latest stable Debian or Armbian release.
Home networking and preventing DNS leaks
I'm thinking of getting my OPNsense device back up again. At my previous place of residence, I had AT&T internet, and AT&T had all sorts of configurable options in their modem that played well with my OPNsense device. At my current place of residence, I have Xfinity Comcast, and the only option I can configure on their modem that would allow me to use my OPNsense device is "Enable/disable bridge mode". When I first moved in here, I tried doing that, but for some reason the IPv4 gateway on my OPNsense device wasn't picking up anything. I believe I had everything configured correctly, the Xfinity modem was in Bridge mode, and the OPNsense router was assigned the public IP address from my Xfinity account. This was four months ago, and it's very likely I missed something in the configuration, so it can't hurt to try again. The worst-case scenario is that I reset my Xfinity modem to factory defaults and continue to use that. But it would sure be nice if I could have more control over that portion of my internet.
DNSSEC wasn’t worth it
[… we] estimate that DNSSEC validation is performed around 1% of the time, given the DNS query profile of today’s data I run my own authoritative nameservers and have had a slight nagging feeling that I should’ve enabled DNSSEC years ago. It’s been on my perpetual to-do list but I’ve never gotten around to it. I’ve definitely caused some outages trying to get DNSSEC to work. Came across this article and it confirms that my procrastination was pretty OK in this specific case.
I Bought a Numeronym Domain Name
Some weeks ago, I read a post from Jan-Luka's where he talked about what to do with his new domain. The most interesting part for me was not what to do with the domain, or the domain itself, but what the domain is: a numeronym.
My own DNS-over-HTTPS Server
With all the hype surrounding DNS-over-HTTPS (DoH), I wanted to try it out for myself and see what it was all about.
Decentralizing My Website With IPFS
How does my website work with IPFS? Where does the content go? What happens when my website is accessed through HTTP? Here's a tale that explains of what happens.
DNS shenanigans post-mortem
Let’s start by saying I probably should have done a bit more research before diving head-first into this endeavor. I’ve been thinking about transferring my domains off google domains for some time now, as part of my personal goal to self host and limit my dependence on google and other large third-party monstrosities. Along that line, I asked for registrar recommendations. ~tomasino responded with namesilo. I found that they had $3.99 registrations for .team and .zone domains, which is 1/10th the cost of the $40 registration on google domains. I started out by getting the list of domains from the […]
Who to host with (domain names, web space, SSL, DNS)
I'm sometimes asked who I recommend buying web infrastructure from. Here's my list based on my personal experience: Domains | SSL | DNS | Shared hosting | Dedicated hosting | Transactional email | Virtual servers Domain names: Namecheap Almost all of my domains are hosted with Namecheap. They're simple, have a super-fast web interface, a straightforward API, and have never messed me around. Most importantly, they're cheap, so I never have to regret a purchase. I transferred my domains from G
