[BBLISA] IPv6, 6to4, and routing

[Edward Ned Harvey]

Many ISP's (but certainly not all) provide you a single real IPv4 address on
whatever the first device is in your location ... usually your own personal
router.  Linksys, or whatever.

 

As long as you have a real IPv4 address, then you can use 6to4 trivially.
By simply clicking the 6to4 checkbox to enable 6to4, you're able to use IPv6
over an ISP which only supports IPv4.  (Side Note:  Which OSes handle this
well?  Win7: Device manager, Action, Add legacy hardware, Microsoft 6to4.
OSX Snow Leopard: Network Preferences, add 6to4.)

 

In a 6to4 address, 16 bits are arbitrarily selected by the device.

 

So I logically conclude:  If your little linksys or whatever router supports
6to4, and it can distribute IPv6 to the autoconfigure clients on your LAN,
that means you don't even need to do *any* thing to your
windows/mac/whatever laptops etc.  Just enable the checkbox for 6to4 in your
little router, and voila, you have IPv6 running on your LAN.

 

Anybody doing anything like this in practice, or am I just talking theory at
this point?    Unfortunately, I can't test it myself, because I'm one of the
saps who doesn't get a real IP address from their ISP.
