IPv4-in-IPv6 , a reverse of today's<BR>> tunnels. Refer to the DS-Lite
standards among others, and this approach<BR>> is part of the 3GPP/LTE
standards for mobile networks migration to IPv6./<BR>> //<BR>> Estimates
I've seen so far from IPv6 day suggest that although traffic was<BR>> up, V6
accounted for between 0.02% and 0.3% of total traffic. Of that,
90%<BR>> was tunnelled (i.e. only 10% native). So basically: (1) there
is no<BR>> signficiant IPv6 Internet today, and (2) if you want to join what
there is,<BR>> you do indeed probably have to tunnel.<BR>> />>
Tunnels solve the chicken and egg problem, it allows IPv6 content to<BR>> be
accessible until IPv6 gains a wider installed base which may take<BR>> years.
During the same time the burden of running IPv4 with no public<BR>> addresses
will grow. Both RIPE NCC and ARIN have publicly endorsed<BR>> tunneling to
speed up IPv6 deployment./<BR>> <BR>> That doesn't mean that
installing a tunnel client is a good idea for anyone<BR>> except network
specialists who know what they're doing.<BR>> />> Protocols that
automate the setup of carrier grade tunnels, such as<BR>> TSP, make
installing tunnels a plug and play affair. Refer to my<BR>> original email
and try it to see for yourself. For zero user<BR>> intervention needs, there
are CPE IPv6 Adapters that plug in an ethernet<BR>> port on an IPv4 home
router and automatically setup IPv6-in-IPv4 tunnels<BR>> (see the ARIN Wiki
on IPv6 CPEs). All these are carrier grade solutions<BR>> and have been
deployed by tier-1 carriers./<BR>> <BR>> If random end-users start
installing this stuff without understanding it,<BR>> then (a) they are
probably opening up security holes into their network, and<BR>> (b) they may
impede a later smooth rollout of native v6.<BR>> />> Whether users
dual-stack or tunnel to IPv6 the security requirements<BR>> are mostly the
same. Waiting for end-to-end dual-stack to be deployed<BR>> all the way to
the home CPE to complete is a multi year project. And I<BR>> don't see
IPv6-in-IPv4 tunnels impeding rollout of native IPv6 if the<BR>> tunnels
clients AND servers are fully under control of the ISP and part<BR>> of their
network. The rule here is for ISPs to avoid using Teredo, 6to4<BR>> and
ISATAP tunnels which, unfortunately, are everywhere./<BR>> <BR>>
