Dear All,   
      
   Does anyone have any experience debugging IPv6 on Android devices? Are there   
   tools and docs?   
      
   My phone and tablet sometimes use IPv6, sometimes they won't, and I find no   
   obvious way to monitor and influence this process.   
      
   I generally use http://test-ipv6.com/ to see if a device is using IPv6 or not,   
   and sometimes it is and sometimes it is not.   
      
   On the wire (actually WiFi), I see Router Advertisements from my FreeBSD   
   router, but sometimes no Router Solicitations from the Android devices, which   
   means their IPv6 support has stopped working again.
