Of course, you don't have to do that, and then it is possible to divide a /64 (would have to use static addressing or DHCPv6) >Consequently, it's hard to make subnets with only a /64.

To handle the connection to Internode, which relies on DHCPv6 would be one option, static addressing another. >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. My router looks after all of that. The router is advertising a /64 prefix to the LAN. I have several IPv6 capable devices - a number of PCs, one Mac, and a handful of iPhones and iPads (yes, the iOS devices support IPv6). >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 Sign of the times. :-) >We'll see more of those.

That would be handy, though the SIP gateways I use don't support IPv6 (yet). 73 de VK3JED / VK3IRL http://vkradio.com _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
