That said, I would argue that most or all 6to4 traffic could just as well use
IPv4, since both parties to the communication obviously have access to a
public IPv4 address. What is the advantage of using 6to4 over IPv4 that makes
it worth suffering an 80% failure rate?
it can communicate with hosts that have only IPv6,
it can communicate with hosts that are stuck behind a single IPv4 address (if
the router acts as a 6to4 gateway) without a NAT being in the way,
it can be used to develop and test IPv6 applications without having to build a
special-purpose network,
it can be used to deploy applications now that already support IPv6 and so are
in some sense future-proofed,
it can be deployed on either a single host or a network
again, trying to judge how well 6to4 works by how well it works with web sites
that also support IPv4 is entirely missing the point.
