Andrews & Arnold (AAISP) has always been at the coal face of broadband, and is leading the charge towards ensuring IPv6 does not get ignored. The free Billion 7800N they provide with new connections is IPv6 capable, but costs the company around £120 to retail.
It appears though that the price of IPv6 capable routers is dropping, with Adrian Kennard hinting that they are close to sourcing a new IPv6 capable router, that is reasonably priced, but still comes with the goodies like DSL and Ethernet WAN ports.
IPv4 is set to run out of available address space in the next year or two, with a system of trading likely to arise for IP address blocks; our guide to IPv6 explains more on the new addressing system.
The cost of the consumer hardware has been a stumbling block to date, thus if capable hardware does start to appear on the market, broadband users will be able to buy hardware in the knowledge that it will not be redundant in two years time or without spending excessive amounts on money.
