<b>Subject:</b> [AusNOG] Default IPv6 Local Only Addressing for Non-Internet Devices</font>

<div>Hi,<br>
<br>
Quite closely related to my recent AusNOG "Getting IPv6 Private<br>
Addressing Right" presentation.<br>
<br>
I recently bought an IPv6 enabled Wifi printer. As it is attached to<br>
my single Wifi SSID it is configuring itself with IPv6 global<br>
addresses, even though I don't need it to be reachable from the<br>
Internet or able to reach the Internet. (It would be relatively hard<br>
to find from the Internet anyway with /64 prefix, and there is an IPv6<br>
firewall in front if it).<br>
<br>
I think it would be better for these types of "Non-Internet' devices<br>
not to configure themselves with global IPv6 addresses by default.<br>
