Rather, more and more IPv6-capable systems will be deployed, and IS management will gain comfort with the availability of the technology -- particularly once they have cell-phones running it -- until at some point the cost of adopting IPv6 becomes less than the cost of maintaining a twisted, hyper-complex multi-layer-NATted corporate network infrastructure. The main barrier to adoption of IPv6 right now is Cisco. While there is a test release of IOS available which supports IPv6, it will probably be another few years before even a large minority of deployed routers support it. Unlike the similar deployment problem with multicast, IPv6 isn't anything hard -- it really is just IP with longer addresses. (By contrast, global-scale IP multicast is a Hard Problem[tm] which still has yet to be solved.) -GAWollman To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
