It should indeed. However, if you're using neighbour discovery (e.g., radvd in Linux) to deliver addresses to hosts, my understanding is that you need to use a /64 due to the way in which the host address is calculated - usually from the MAC address. Consequently, it's hard to make subnets with only a /64. Some people, for example, prefer to separate wired and wireless networks. Internode provide a /56, which should be more than enough for anything short of a large organization. I suspect you could work around the above issues using DHCPv6. I haven't looked at the available DHCPv6 servers in quite a while. When I last checked, ISC DHCP still had significant catching up to do, especially in its support for prefix delegation. To handle the connection to Internode, which relies on DHCPv6 prefix delegation to supply the /56 block, I use wide-dhcpv6-client; I then let neighbour discovery (via radvd) propagate addresses to the local LAN, which in practice means my laptop, as the other devices on the LAN are all IPv4-only equipment such as a SIP phone and a printer. Incidentally, a friend recently bought one of these multifunction (printer/scanner/fax) devices, which supports IPv6 in its networking firmware: http://www.brother-usa.com/mfc/modeldetail.aspx?PRODUCTID=mfc7860dw&tab=spec We'll see more of those. I also know people who would like to become informed of any IPv6-capable SIP phones on the market. _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
