You're the sort of cool nerd who knows all the weird esoterica which makes up DNS, right? In amongst your A, AAAA, SOA, and MX records, there's a little used NAPTR. Yes, you can use DNS to store Name Authority Pointers! What?! It is yet another of those baroque standards which spits out things like: cid.uri.arpa. ;; order pref flags service regexp replacement IN NAPTR…

I love DNS esoterica. Weird little things that you can shove in the global directory to be distributed around the world instantly(ish). Domain names, like www.example.com usually resolve to servers. As much as we think of "the cloud" as being some intangible morass of ethereal Turing-machines floating in probability space, the more prosaic reality is that they're just boxen in data centres. They …

There's a new Web Standard in town! Meet WebMonetization - it aims to be a low effort way to help users passively pay website owners. The pitch is simple. A website owner places a single new line in their HTML's <head> - something like this: <link rel="monetization" href="https://wallet.example.com/edent" /> That address is a "Payment Pointer". As a user browses the web, their browser takes …

I've written before about the moribund BIMI specification. It's a way for brands to include a trusted logo when they send emails. It isn't much used and, apparently, is riddled with security issues. I thought it might be fun to grab all the BIMI images from the most popular websites, so I can potentially use them in my SuperTinyIcons project. BIMI images are SVGs. Links to a site's BIMI are…

You type in to your browser's address bar example.com and it automatically redirects you to the https:// version. How does your browser know that it needed to request the more secure version of a website? The answer is... A big list. The HTTP Strict Transport Security (HSTS) list is a list of domain names which have told Google that they always want their website served over https. If the user …

How should I design my personal DNS for all the cool new Federated Services and IndieWeb protocols? Way back in the early 2000s, I started this website - shkspr.mobi. A few years later, I added a blog. I could have used the main domain, or created a subdomain like blog.shkspr.mobi. In the end, I chose a subdirectory of shkspr.mobi/blog I don't know if that was the right choice back then, but…

You know how it is, you buy one silly domain name and then you get an idea for loads more! A few weeks ago, I got https://⏻.ga/ - I think I'm the first person to get a domain name which uses a glyph from the Miscellaneous Symbols Unicode block. How exciting! And that got me wondering… what other abuses of the Punycode algorithm can I whack into DNS? Well, here's some I whipped up using FreeNom …

I'm concerned about the longevity of the domains I register. I want my domains to be available for as long as possible. But it seems that every year prices rise - and the discount often provided for a new domain rarely continues into subsequent years. So I recently started renewing them for as long as possible. It turns out that most domains can be registered for a maximum of 10 years. A…

You've been on the Internet a long time, right? Of course you know what BIMI is. All the cool kids do. But, for those of you who aren't hip to the jive of the Infobahn... BIMI (Brand Indicators for Message Identification) is a new standard that can curb the issue of online impersonators. ... BIMI is a new standard that enables you to include your company’s logo alongside the emails you send. T…

As part of my new job, I'm learning a lot more about the mysteries of the Domain Name System than any mortal should know I thought possible. The humble unix dig command allows you to query all sort of DNS information. For example, to see name server records for the BBC website, you can run: dig bbc.co.uk NS Which will get you: ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: …

It's useful to share negative results. Not every experiment has an amazing or successful outcome. tl;dr you can't register Punycode .ss domains. This also means Internet users in South Sudan can't register domains using their own writing system. Background The Republic of South Sudan became independent and joined the United Nations back in 2011. A decade later, and it's now possible to…
