    Another disadvantage of Teredo is that it's tunneled over UDP (in turn over IPv4), so you have a limit of about 63,500 IPv6 addresses behind a single public IPv4 address. I haven't hit that limit at home yet...

    RFC3056, on the other hand, allows 16 bits' worth of IPv6 networks behind a single public IPv4 address. However, it won't work with older consumer-grade firewalls that only pass TCP, UDP and (sometimes, if you're lucky) ICMP.
