Nearly all ADSL routers only talk IPv4 as far as I'm aware.

Until they can be replaced or upgraded with firmware that supports IPv6 
then IPv4 isn't going away.

Also, as far as I understand it, whilst IPv6 clients can talk to IPv4 
servers via a gateway, an IPv4 client can't talk to an IPv6 only server. 
So IPv4 will be required on the servers for as long as there are IPv4 

Upgrading residential access equipment ought to be the industry's top 
priority as (a) it would mean that servers could be deployed IPv6 only; 
and (b) large blocks of IPv4 space could be released to help smooth the 

Ain't gonna happen any time soon though.
