IPv6-Only Is Becoming Viable 209
An anonymous reader writes "With the success of world
IPv6 day in 2011, there is a lot of speculation
about IPv6 in 2012. But simply turning on IPv6 does not
make the problems of IPv4
exhaustion go away. It is only when services are usable
with IPv6-only that the internet can clip the ties to the IPv4 boat
anchor. That said, FreeBSD, Windows,
and Android
are working on IPv6-only capabilities. There are multiple
accounts of IPv6-only
network
deployments. From those, we we now know that
IPv6-only is viable in mobile, where over 80% (of
a sampling of the top 200 apps) work well with
IPv6-only. Mobile especially needs IPv6, since their are only
4 billion IPv4 address and approaching 50
billion mobile devices in the next 8 years. Ironically,
the Android test data shows that the apps most likely to fail are
peer-to-peer, like Skype.
Traversing NAT and relying on broken IPv4 is built into their method
of operating. P2P communications was supposed to be one of the
key improvements in IPv6."
