Not to beat a dead horse, but could the problem be so simple? I have tons of dual-stacked machines that have updated forever without issue, so I assume they update via IPV4. That being said, I've not packet sniffed any of the update stuff in a while but if the DNS is any indication then dual-stacked machines can update via IPV4 while IPV6 ONLY machines will likely fail since the DNS shows IPV4 only.... host windowsupdate.microsoft.com windowsupdate.microsoft.com is an alias for windowsupdate.redir.update.microsoft.com.nsatc.net. windowsupdate.redir.update.microsoft.com.nsatc.net is an alias for redir.update.microsoft.com.nsatc.net. redir.update.microsoft.com.nsatc.net has address 157.56.77.153 On 11/11/2018 01:35 PM, Jared Mauch wrote:

Also no problems here with IPv6 and Windows Updates...
The issue is affecting (and has affected) quite a few folk:

It occurs to me that this, could, perhaps be CDN specific.
I'm currently not in Johannesburg, but last time I checked, the majority of Windows updates were being handled by Akamai. Perhaps this is where the issue could be, although we have got local IPv6 peering with Akamai and don't generally have issues with it.
I'll dig deeper into how Akamai may be involved when I get back home.
Let me know if you see anything related to Akamai. Looking at these threads I don’t see anything really obvious and some are much older posts.
