Hey 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.

Hi HN - I’m the developer of PingStalker, a macOS utility I built to see what’s really happening on the LAN/WLAN. I live in the CLI, but when it came to discovery and monitoring, I found it limiting. So I built a GUI that brings my favorite tools together in one place. PingStalker started because I wanted to know if something on the network was scanning my machine. I also wanted quick access to core details—external IP, Wi-Fi data, and local topology. Then I wanted more: fast, reliable scans using ARP tables and ICMP. As a Wi-Fi engineer, I couldn’t stop there. I kept adding ways to…

I had a work objective that required me to be able to "slice" a subnet by a smaller subnet and I didn't manage to find any other libraries that accomplish this kind of computation so I set out to write one myself. Supports calculating CIDR unions, differences, and complements. The rest of the existing set operations don't really make sense for CIDRs since the only way they can overlap is if one fully contains the other (or they are equivalent). I figured a binary tree-like data structure would be the most memory efficient way to represent this, but I'm super open to any feedback especially…
