Detecting Tailscale VPN Using Test Net Function?

This is rooted, A12, Moto XT2215-4. I know already about the VPN Connected state. That is really not what I want and I saw in the docs here that the Test Net function can return VPN: Possible Connection Types are none, mobile, wifi, mms, supl, dun, hipri, wimax, bluetooth, dummy, ethernet, and vpn. So I was hoping that when on mobile data with Tailscale enabled, I would get vpn. But I get mobile - which is true, of course. I suppose it is possible to have a vpn piggyback on most other forms of connection (at least ethernet, wifi, mobile). Indeed, it strikes me that a vpn MUST - by definition - use an underlying network. So is there a problem of "precedence" here? It seems to me, perhaps wrongly, that if a vpn is indeed connected, that the value of vpn should be returned (not the underlying network) if only one value can be returned. submitted by /u/TooManyInsults [link] [comments]
