The infrastructure underlying AS54316 -- the network supporting the services offered by the AP Foundation -- has historically been based out of a datacenter in NYC (NetActuate in Telehouse Chelsea). To add some resiliency, I thought it'd be interesting -- and a potentially fun challenge -- to leverage some spare real…
Since 2014 this blog has extensively covered the wireless networks built by high-frequency trading (HFT) firms or network providers to reduce latencies between the different exchanges around the wo…
No corporate parables or historical insights this week, just the odd and sometimes amusing tale of the author's multi-decade quest for internet connectivity.

Yesterday, during OsmoDevCon 2018, Steve Markgraf released osmo-fl2k, a new Osmocom member project which enables the use of FL2000 USB-VGA adapters as ultra-low-cost SDR transmitters. How does it wor
Yesterday I read this toot (German) over on mastodon which starts with “IPv6 is hard.” No it’s not. It’s different. I ran across this multiple times: There is an A and an AAAA-record for a FQDN, but the web server is only reachable via IPv4. You can easily test this with curl $ curl -4 https://github.com -o /dev/null…
Update (2021-10-31): DuckDuckGo now includes results for Wikivoyage again, as do Bing and Yahoo. I have been planning a long due vacation and I was doing some research into the places I wanted to visit. My goto travel guide is Wikivoyage: it’s well organised, text-heavy (instead of slideshow-heavy alternatives) and…
I updated the whoami.filippo.io dataset! I explain how it works, and how I fetched the new data.

*without doing much with it (and maybe not for long at its current growth rate)
X.400 promised recallable, scheduled, self-destructing email. Why simple SMTP won instead, and what we lost and gained when it did.
DNS over HTTPS (DOH) is a feature where a client shortcuts the standard native resolver and instead asks a dedicated DOH server to resolve names. Compared to regular unprotected DNS lookups done over UDP or TCP, DOH increases privacy, security and sometimes even performance. It also makes it easy to use a name server…

Learning how the IMAP protocol actually works
I'm a software and network engineer living on the west coast. I currently work at Qumulo writing a petabyte-scale CDN with linearizable reads and writes at every edge. Previously, I worked at Arista Networks doing network automation, large scale digital-twin network validation, and routing for SMPTE2110 networks.
There is again a pull-request submitted to the curl project to bring support for the Gemini protocol. It seems like a worthwhile effort that I support, even if it is also a lot of work involved and it might take some time before it reaches the state in which it can be merged. A previous … Continue reading The Gemini…
I like things that are strange and a bit obscure. It’s a habit of mine, and a lot of this blog is to document things I haven’t heard of before, because I wan...
Notes from setting up Prosody in Docker for federated messaging, with file sharing, voice calls, and end-to-end encryption.
TL;DR: Fritz!Box devices using custom DNS resolution services like Pihole or Adguard might have been compromised by DNS hijacking and using those Fritz!Box devices might be unsafe, especially for Windows users. Update: I updated the article to downscale the severity of the situation. After posting the article on HN, I…
Privileged ports were a security feature in the days of dumb terminals, in the age of the World Wide Web, they are a security vulnerability.

FM radio headphones were given out at the door. Each set was tuned beforehand to receive a broadcast from my programmed station. Visitors were then invited to walk around the room, contemplating the artifacts of the exhibit.
My ISP was tampering with my DNS queries and handing back bogus IP addresses. Here are the misconceptions about DoH, DoT and DNSSEC that followed, and the setup I actually run.
