Just added Web Reachability API (at least that’s what I’m calling it) support to https://ip.small-web.org.

It’s for testing the reachability of your Small Web servers (using a domain or, more importantly, an IPv4/IPv6 address). I’m using it to implement Web Numbers¹ support in Auto Encrypt² and Kitten³.

Protocol:

• At http://<endpoint> return an empty HTTP 200 response that includes the following custom header: 'web-reachability-id': ‘<uuid>'
• Hit: https://ip.small-web.org/reach/<endpoint>/<uuid>/
• If you get a 200 response back, your endpoint is reachable. Anything else signals an error.

Enjoy! 💕

🎉 Another quick Node Pebble release (version 5.4.0)

• Adds short-lived profile support. (Thanks to Aaron Gable for showing me how¹)

This should help if you’re implementing support for IP-address certificates.

Thanking the @letsencrypt folks for the excellent work they do, and especially for their upcoming support for security certificates for IP addresses which is nothing short of revolutionary for the future of the (Small) Web.

Introducing Web Numbers

Domains? Where we’re going, we don’t need domains!

Get ready for an exciting new (old?) way to address (small) web sites in 2026.
