Do you not get one or did you not include it? In my previous post, I was showing the ipconfig information for my Windows 2003 server which uses static IP assignment on its LAN interface, so no "Temporary" IPv6 address is present (also the ipconfig command in Windows Server 2003 and Windows XP does not explicitly identify the different IPv6 addresess; that has to be done using the netsh command). Shown below is the "netsh int ipv6 show addr" command for that server which does identify the different IPv6 addresses (but there is no "Temporary" address because static IP assignment is used).

Someday, I may fully migrate into the 21st Century, but for now just getting IPv6 implemented is more than enough of a change. -- We can never have enough of nature.

I also use DHCP-PD, but in my D-Link router that is a separate configuration option from "Stateful" and "Stateless". If I select the "Stateful DHCPv6" option, my Windows XP and static IP boxes don't get native IPv6 addresses (the dual NIC server boxes do however revert to using Comcast's 6to4 tunnel). -- We can never have enough of nature.

For some reason my m0n0wall system log is being flooded with something to do with that DHCP-PD configuration: rtadvd[4649]: received RA from fe80::201:5cff:fe22:c9c1 on non-advertising interface(fxp1)
