[Freeswitch-users] ipv6 - any fans?

[Kristian Kielhofner]

Assuming you're in the US (or most other parts of the world besides
Asia); it won't work.  Here's why:

Almost no last mile providers will deliver native IPv6 (currently).
Your customers would have to use a tunneling service like HE to even
get to you.  First there are hassles setting up the tunnel in the
first place, then there are issues with latency, packet loss, jitter,
etc using a tunnel service that has to haul all of your IPv6 in IPv4
traffic back to their gateway in a central location.  VoIP is just
about the worst service you could use via an IPv6 tunnel.

You could try to offer your own IPv6 tunneling service but there's
still the issue of customers setting up there end of the tunnel.
Besides, encapsulation sucks.

The IPv4 global routing table has at least 424,000 networks:

The IPv6 global routing table has 10,215 networks:

Granted IPv6 networks tend to be better organized and more "compact"
(at least as far as advertisements are concerned) but that's still a
factor of 40:1.
