FWIW, I have a netbook (Windows 7) which does something interesting. I bring it up because it is something that may be applicable to CentOS.There is a tunneling pseudo-interface which is only IPv6; it has two addresses, the IPv6 address, and a local-link IPv6 address. The hardware interfaces also have two addresses, an IPv6 local-link back to the tunnel, and an IPv4 address given by the router.
However, I am not sure that this is efficient for anything other than a light-use personal machine, and unfortunately I'm not sure what happens when it is connected to an IPv6 router! ):
Attached is a screen shot since I'm not sure that my description gave it justice.

I think that site-local ("fec0:: - fef::") is the ipv6
more-or-less-equivalent of ipv4 private addresses.
