Just like the song: "...you know is sad but true..". ISPs and a few vendors offers IPv6 cappabilities as an add-on on its commercial portfolios. For the static v6 address assignment, applies the same. Even if for users represents advantages on having it's own unique address (i.e. in order to enter the Web or apps service providers world for their own), as so for ISPs to perform some network administrative tasks. I favor static prefix assignation over dynamic, but also I think that for some time (more or less until vendors and providers recovers invertion and operation costs) this will be a "expensive product" to adquire. *Daniel Espejel Perez *
