Introduction As a Network engineer, I’ve always dreamed of announcing my own BGP routes and peering with others. I wanted the experience of running a decentralized BGP network not just in a lab environment, but in a real, persistent setup that could run indefinitely. After some research, I discovered DN42, a community driven platform that makes this possible without requiring expensive ASNs or public IP allocations. With DN42, I can establish my own autonomous system, peer with other network enthusiasts, and even run my setup on a home router or a Raspberry Pi. This blog will document my journey into selfhosted BGP, the challenges I faced, and how I built my own decentralized network. If you’re a networking enthusiast looking to explore BGP beyond traditional environments, you’re in the right place! ...

Introduction I’ve been using Tailscale for years to access my home lab without the need for a public IP. Tailscale can be installed on almost any device, allowing you to securely connect and access them from anywhere. It works as a peer-to-peer, mesh-style VPN, is opensource, and completely free for up to 100 devices and 10 users. They also offer a business plan for larger setups. What always fascinated me was how Tailscale works seamlessly across platforms like Linux, macOS, Android, and Windows. Since I use both Linux and Windows in a dual-boot setup, I started digging deeper. On Linux, it’s straightforward they rely on a TUN interface. But on Windows, I was curious about the Layer 3 adapter being used under the hood. After exploring the Tailscale GitHub repo, I discovered that it uses Wintun a TUN driver for Windows developed by the WireGuard project. ...

Introduction I came across a few posts on the subreddit r/selfhosted about running personal mail servers on cloud VPS. That got me thinking why not self-host my own email server at home instead of relying on a cloud provider’s VPS? This led me to wonder what I’d need to set up a fully functional email server for personal use. Rather than using a traditional server-grade PC. I decided to try it on a Raspberry Pi, which is small size and low power consumption make it an ideal choice for use as a home email server. ...
