My hardware is google chromebook. Then i installed *Ubuntu 12.04* via
Crouton on the chromebook. Currently i'm doing connect with IPv4
address. Samsung Galaxy 7 smartphone (mobile hotspot) is the gateway for
public INTERNET.   
  
Question: Can i configure IPv6 address to establish public INTERNET? 

Sincerely,
