It comes up reasonably often that a host has IPv6 configured but broken or non-functional in some way. One recent example is https://github.com/gitpod-io/gitpod/issues/8049 where the sypmtoms were: 1. an error message and health check failure about ip6tables 2. MagicDNS didn't work, even for IPv4 MagicDNS is broken because the failure to initialize IPv6 returns an error which stops the rest of the initialization. I think we have another case where IPv6 failing results in not acceping IPv4 subnet routes. Clearly we'd prefer not to have subsets of functionality be mysteriously broken. This PR is not the right way to do it, but serves as a proof of concept that tolerating IPv6 failures results in fixing https://github.com/gitpod-io/gitpod/issues/8049 without needing the workaround which gitpod put together.

Tailscale
Private WireGuard® networks made easy
Overview
This repository contains all the open source Tailscale client code and
the tailscaled daemon and tailscale CLI tool. The tailscaled
daemon runs on Linux, Windows and macOS, and to varying degrees on FreeBSD, OpenBSD, and Darwin. (The Tailscale iOS and Android apps use this repo's code, but this repo doesn't contain the mobile GUI code.)
The Android app is at https://github.com/tailscale/tailscale-android
The Synology package is at https://github.com/tailscale/tailscale-synology
Using
We serve packages for a variety of distros at https://pkgs.tailscale.com .
Other clients
The macOS, iOS, and Windows clients use the code in this repository but additionally include small GUI wrappers that are not open source.
Building
go install tailscale.com/cmd/tailscale{,d}
If you're packaging Tailscale for distribution, use build_dist.sh
instead, to burn commit IDs and version info into the binaries:
./build_dist.sh tailscale.com/cmd/tailscale
./build_dist.sh tailscale.com/cmd/tailscaled
If your distro has conventions that preclude the use of
build_dist.sh, please do the equivalent of what it does in your
distro's way, so that bug reports contain useful version information.
We require the latest Go release, currently Go 1.19.
Bugs
Please file any issues about this code or the hosted service on the issue tracker.
Contributing
PRs welcome! But please file bugs. Commit messages should reference bugs.
We require Developer Certificate of
Origin
