    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.

    A server that replies to your pings faster than ever! Now with IPv6 support. Give it a minute and the response time will go down tremendously: ping ftlping.net On Windows, add an option not to stop after 4 pings: ping -t ftlping.net Works best on MacOS and FreeBSD. Not impressive on Windows but you can see something interesting if you run a packet analyser. Report issues here: https://github.com/plingbang/ftlping/issues The code may be published when my future self passes it to me.

    Howdy HN! I find myself testing my ping from time to time, especially when my internet seems wonky while WFH. It feels like there should be an easier way test my ping than puling up a terminal or a complex web app - especially when I'm on my phone or any other device that doesn't have a terminal. I figured I should be the change I wish to see in the world and created this super light ping test. I also created a latency monitoring solution (https://github.com/cjjeakle/network-monitor), feel free to clone and try it out! I know there are a lot more mature monitoring…

    Hi HN, To truly understand how operating systems and network protocols work, I decided to combine two classic learning tools: the xv6 teaching OS and a from-scratch TCP/IP stack. I'm excited to share the result: my own from-scratch TCP/IP networking stack running directly inside the xv6-riscv (https://github.com/pandax381/xv6-riscv-net) kernel. The project uses a modern virtio-net driver, allowing it to run seamlessly in QEMU and communicate with the host machine. Key features: - From-Scratch Stack: The core is powered by microps…

    ping6.it can compare IPv4 vs IPv6 side by side, from the same probes. You can run: - ping - traceroute - mtr - dns - http …and immediately see where v6 behaves differently (latency, loss, reachability, path).

    Hey HN, I built a menu bar utility to monitor VPN status and detect leaks on macOS. The problem: macOS doesn't make it obvious when your VPN silently disconnects, and even when connected, DNS or IPv6 traffic can leak outside the tunnel without you knowing. VPN Peek shows your connection status at a glance and runs leak detection: - DNS leak detection: checks if your DNS queries go through your VPN or leak to your ISP - IPv6 leak detection: detects if your real IPv6 address is exposed - Shows current public IP and location - Notifications when VPN drops or leaks are detected - Auto-refreshes…

    For the past months we've been working on making our open source tool Internet.nl easier to deploy and develop on. Last week we release version 1.8.0 (https://en.internet.nl/article/release-1.8/) which includes these changes. Tests include: IPv6, DNSSEC, HTTPS/TLS, various security options like XSS, CSP headers, security.txt, RPKI, DMARC, DKIM, SPF, STARTTLS, DANE for web/email, and a browser connection test for IPv6 and DNSSEC. (see: https://en.internet.nl/faqs/) Using Docker & Docker Compose it is now trivial to deploy your own…
