From IPv6.rs FAQs I get the impression that they only provide IPv6 route through their tunnel. I think self-hosting something only reachable via IPv6 would cause you trouble accessing it in IPv4 only networks - which are still far more common compared to IPv6.

Hurricane Electric provides such IPv6 over IPv4 tunnel facility with /48 block routed to your network. I’ve only used this service for testing my IPv6 knowledge, so performance-wise I’m not sure how good it is. Thus, if IPv6.rs provides a significant performance over the HE-TunnelBroker, then I’d suggest you go with IPv6.rs given a decent price for the service.

If you are considering a simple to set-up tunnel utility for your self-hosting applications, I’d suggest you consider other tunneling options which have both IPv4 and IPv6 capabilities. Some widely used ones are Cloudflare Tunnel and Ngrok. You may also use Tailscale to connect both server and client via VPN. Using Cloudflare or Ngrok would involve some privacy concerns, as they can see the traffic passing through the tunnels in plain text.

+1 for recommending Fossify over ‘SimpleApps’

Extending the reply for ‘Sandboxed Play Store … F-Droid … Aurora Store’ -

1. In case of Sandboxed Play Store - we’d need to login via a Google account in order to be able to download apps. Also, when we allow network access to the Play Store, it may send device info, app downloaded, updated etc related telemetry to Google. Also expect the promoted apps/games ads in the Play Store home screen.
2. In case of Aurora Store - we can use it via Anonymous User or we can supply our own Google Account. Aurora Store just uses the credentials to download apps from Google Play, but other telemetry is limited compared to Play Store.
3. In case of F-Droid store - It mostly hosts open-source Apps. And has cautions whenever an app uses proprieray libraries, code or needs access to specific network(eg - Telegram FOSS needs Telegram Servers access to function) in order to work.

I’d recommend you have both - F-Droid and Aurora Store. If you need to access the Play Store subscriptions, then you’d need to install Play Store as well.
