24 alternatives to We Implemented the IPv8 Internet-Draft in Linux, Libc, and BGP
A few weeks ago, an Internet-Draft titled Internet Protocol Version 8 (IPv8) caught our eye.
A team at goonhost.rocks implemented the IPv8 Internet-Draft specification across Linux, Musl Libc, and BGP systems. IPv8 expands IP headers by adding 4 bytes each to source and destination addresses, increasing the… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

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, 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…

Hi HN, For the past few months, I've been exploring tools that integrate with the Linux networking stack. This led me to build SafeHaven, a lightweight and configurable VPN implementation written in Go. The goal was to better understand how virtual private networks work at a fundamental level. Would love feedback from the community! Repo link: https://github.com/kwakubiney/safehaven

Over the last few years, I've needed an easy way to quickly serialise and deserialise various network protocols safely and efficiently. Most of the libraries that existed at the time were either quite heavy, had less than stellar performance, or were an abstraction level above what I was looking for. I decided to put together my own class to do the job, starting with an easy, low-overhead way to move bytes in and out of arbitrary buffers. Along the way, it picked up useful bits and pieces, such as buffer structures and allocators that made the byte shuffling faster, often being able to do it…

I'm the founder at Netrinos. I built a WireGuard-based mesh VPN because remote access has always been a pain. After years of SSH tunnels, IPsec headaches, and the ssh log horror movie, I wanted something simpler: install, sign in, get work done. Netrinos creates a LAN-like overlay network across your devices. Connections are direct P2P via WireGuard, with no central server routing traffic. Each device gets a stable IP and DNS name (pc.you.netrinos.com). When direct connections fail, they fall back to a relay server that's still encrypted end-to-end. We can't see your traffic. The most…

Hey HN! I just released go-nbd, a lightweight Go library for effortlessly creating NBD servers and clients. Its a neat tool for creating custom Linux block devices with arbitrary backends, such as a file, byte slice or what I'm planning to use it for, a tape drive. While there are a few partially abandoned projects like this out there already, this library tries to be as maintainable as possible by only implementing the most recent handshake revision and baseline functionality for both the client and the server, while still having enough support to be useful. I'd love to get your feedback :)

Hey everyone. It's Sherub here, author of the Build your own DNS Server challenge on CodeCrafters. Currently it’s available in Rust, Go, and Python and is free while in beta. https://codecrafters.io/dns-server I've kept the challenge accessible but still challenging for an intermediate developer. This challenge, like others from CodeCrafters, is self-paced. You can use any tools you prefer (terminal, editor, etc.) to build the project. At the end of the challenge, you will have created a DNS forwarding server. The server can create and read DNS packets and respond to DNS…

I built a chained VPN lab to support multi-user traffic isolation using only raw Linux tools. Each user gets: - A WireGuard tunnel - A dedicated namespace (wg-$user) bridged via veth - NAT and routing table override - A second namespace (ovpn-$user) running OpenVPN - Final egress through tun1 The entire setup is controlled with bash scripts and PostgreSQL — no Docker, no containers, no Python, just raw netns, iptables, ip rule and shell. Built for GDPR-compliant VPN infra with real isolation per collaborator. Code and README:…
