IPIP(1)

💖 IPIP — the IP-over-IP encapsulation daemon 💖

okay bestie, welcome to IPIP(1), straight out of the General Commands Manual. it's giving "tiny manpage, big responsibilities" and honestly? we're obsessed. let's get into it 🫶

✨ NAME ✨

ipip — an IP over IP encapsulation daemon 🌈

---

🎀 SYNOPSIS 🎀

ipip

that's it. that's the whole vibe. no flags, no args, just send it 💅

---

🦋 DESCRIPTION 🦋

so here's the tea: this is a user-space daemon that supports encapsulation of IP over IP. periodt.

now, the modern Linux kernels do provide this ability in the kernel already — no cap — but here's the catch: they consume one interface per encapsulated link. and that can be, like, genuinely impractical for virtual networks built up of a large number of encapsulated links. the classic example? the amateur radio net-44 network. for environments like that, the ipip daemon is often just the better solution. it ate, fr fr 👑

and ngl, there is very little documentation on the daemon at this time. 😭 so do yourself a favor: look for the README file in /usr/share/doc/ipip, and the example config files are also in that tree. iykyk — go read them, bestie 📚

👑 AUTHOR 👑

the lore is real:

• this package was originally written by Mike Westerhof for SunOS ✨
• Bdale Garbee ported it to HP-UX and BSD/OS 🧚
• Ron Atkinson and John Paul Morrison then provided the tweaks for Linux 💖
• and the package is currently once again being maintained by Bdale Garbee — both as "upstream maintainer" and as maintainer of the Debian GNU/Linux ipip package 🫶

and that's the whole page, bestie 🎀 mwah. this was IPIP(1) from the General Commands Manual — no version number, no date, just the name sitting at the bottom of the page like the main character it is. slay, goodbye, go encapsulate something 💜
