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…

Hello! I'm learning Rust and also information security, so what better way to learn than to put a tool together practicing both skills? I've tried to use a couple of different tools for subdomain enumeration (part of the Discovery-party when it comes to penetration testing), but none of them were very fast, even if the DNS resolver I pointed them towards is, so I wrote my own tool that leverages concurrency to check a lot of subdomains, fast! It's written in Rust, main parts being using Tokio and async_channels, and I think it works good enough for a first release. I wanted to get recursive…
