If you want to deploy IPv6, but your current Internet Service Provider (ISP) does not offer IPv6 addressing, consider the following alternatives:
Hire another ISP to provide a second line for IPv6 communications from your site. This solution is expensive.
Get a virtual ISP. A virtual ISP provides your site with IPv6 connectivity but no link. Instead, you create a tunnel from your site, over your IPv4 ISP, to the virtual ISP.
Use a 6to4 tunnel over your ISP to other IPv6 sites. For an address, you can use the registered IPv4 address of the 6to4 router as the public topology part of the IPv6 address. For more information, see How to Configure a 6to4 Tunnel in Administering TCP/IP Networks, IPMP, and IP Tunnels in Oracle Solaris 11.2 .
