Backname.io – every IP address gets its own domain
I was setting up tests involving DNS resolution recently, where something like 127.0.0.1.service.foo would have been tremendously useful. Back in the day, I'd have used xip.io - but sadly that service died. Well, every excuse is a good one when it comes to writing a DNS server! Backname.io joins nip.io and sslip.io in the wildcard DNS game.
Backname.io – every IP address gets its own domain launched on September 28, 2023 with 46 votes, #1,305 of 4,228 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 3 years on.
In plain words
Backname.io is a wildcard DNS service that automatically resolves IP addresses embedded in domain names to those addresses. Developers and testers use it to set up DNS resolution testing without manual configuration—for example, 127.0.0.1.service.foo resolves to 127.0.0.1. It serves as a replacement for the defunct xip.io service and operates similarly to nip.io and sslip.io.

We launched an API for custom hostnames today. A simple HTTP post with a hostname gets a temp hostname with CNAME/a record instructions, as soon as DNS is setup we issue SSL and start accepting traffic for that hostname. It's the quickest way we know of to provision custom hostnames: https://fly.io/mix/custom-hostnames/ When we started building Fly, we figured it was too late to "make SSL easy and the customers will come". Lets Encrypt changed the world, and we knew many companies rolling their own SSL support with nginx, Traefik, etc, etc. It seemed like a…

IP Guide – Info on IP addresses, Networks, and ASNs2023 · ip.guide · ▲363Hey all, wanted to share my recent weekend hack project. I wanted to improve upon the existing space for looking up information about IP addresses and ASNs. The backend is written in Rust and pulls BGP data every 8 hours from the RIPE RIS project to build up a routing table and also adds geolocation information. The frontend is using React and Tailwind. Would love any feedback or suggestions on what to improve.
