Interestingly enough this time with the MAC address of the Ethernet interface (the initial one was derived from the Wi-Fi interface, with this being the only one available at the time), even though the Ethernet interface had a higher interface ID/number (as of Windows’s own notation) and was disconnected when the system rebooted. The result was that, after another reboot, the DUID was overwritten by a new LLT based one.

At a later point (after installation of the drivers for the wired Ethernet NIC) I tried to change the DUID to an LL-type one by deleting the registry key and putting a “00 03 00 01 E4 A7 A0 5B 85 E2” into the key (which should be a valid one according to RFC 3315, sect. 9.2) which actually doesn’t come as a surprise given Windows (like many other OSs) has been using this as default in the past (and RFC 3315 recommends this for systems “that contain some form of writable non-volatile storage”).

After installing the drivers for the WiFi interface and rebooting the following DUID was created:Īs we can see this is a DUID “Based on Link-layer Address Plus Time ” ( RFC 3315, sect.

This in turn meant that the system performed the first full boot process without any network adapters which had the consequence that no generation of the DUID took place. The installation was done on a laptop from our lab and interestingly both the build-in wireless and wired NICs were not recognized properly in the course of the procedure. Let’s quickly look at the generation of the system’s DHCPv6 DUID. Set-NetIsatapConfiguration -State DisabledĪnd, of course, this could be done by means of GPOs. This can be done in PowerShell, too: Set-NetTeredoConfiguration -Type Disabled Given I don’t think that there’s much need (dynamic) tunnel technologies nowadays (let alone on systems acting as “servers” one notable exception being servers offering DirectAccess services, as Richard Hicks rightfully pointed out) I did not perform any further investigation on them but immediately disabled both by: netsh int isatap set state disabled Tunnel adapter Teredo Tunneling Pseudo-Interface: : Media disconnectedĬonnection-specific DNS Suffix. ISATAP as well Teredo adapters were present after the installation (more precisely: after the first successful installation of a network adapter, see below): Tunnel adapter :

I assume that except for some settings “tweaked for a server role” (like the creation of temporary addresses being disabled by default) the behavior of Windows 10 will be pretty similar to what’s described below, but one of my colleagues will test this in detail soon (results then presented in an update post to this one, or maybe in a future revision of this Internet Draft). This is the Windows version I looked at: Microsoft Windows Īs of this article this equates to Windows 10 Anniversary Update but I tested an installation of “Windows Server 2016 Standard”. I hence hope this post can somewhat contribute to public knowledge of the intricacies of their latest IPv6 stack. stuff like registry parameters to control it etc.) but I’m not aware of such a document for Server 2016 or Windows 10. many years ago Microsoft published white papers with details as for the TCP/IP parameters of their OSs (incl.obviously for both IPv6 planning and operations it might be helpful to understand the respective behavior of individual operating systems (which is why we researched stuff like this or this in the past).as I laid out in this post the configuration approach an organization takes for their servers might depend on the support of specific features.(here you may keep in mind that the ~50 IETF meetings having passed since the publication of RFC 2460 provided ample opportunity for creative minds to come up with ever new ideas for “enhancing” IPv6, without too much real-life feedback/reality checks from enterprise space though, as simply not many of such organizations have deployed it at scale… or are incentivized to send their employees to week-long meetings in expensive hotels on other continents twice a year…). Server 2016 is the latest OS released by Microsoft so this might give an indication as for their plans & strategy when it comes to supporting certain specifications.I perform(ed) this exercise for several reasons: In this post we’ll take a detailed look at the properties of the Windows Server 2016 IPv6 stack.
