IPV6 dhclient (DUID) on Windows 10 ?

wlambrechts

Hi,

I got this Oneprovider server (in fact an online.net server) and I requested a IPv6 for it. I got this information for it: https://documentation.online.net/en/dedicated-server/network/ipv6/prefix

For Ubuntu I managed to get it working, on Windows 10 though, I found this information: https://documentation.online.net/en/dedicated-server/network/ipv6/prefix

But whatever I do, it does not work: when I change the Dhcpv6DUID registry key and I reboot the server, it resets to the old value ?

I have been pulling my hair out on this. Any suggestions ?

Thanks !

I remember using Dibbler (http://klub.com.pl/dhcpv6/) to get IPv6 working on my online.net windows server. It's old and buggy but unless there is another DHCPv6 client for windows that supports DUID you're stuck with it. I found this old tutorial https://blog.kingj.net/2014/01/03/how-to/ipv6-with-online-net-and-dibbler/ which should help you get started with it.

Sometimes, when DHCP generate new ipv6 for new install it is generate it randomly. In such case you can try something like this:

netsh interface ipv6 set global randomizeidentifiers=disabled store=active
netsh interface ipv6 set global randomizeidentifiers=disabled store=persistent
netsh interface ipv6 set privacy state=disabled store=active
netsh interface ipv6 set privacy state=disabled store=persistent

Above command disable randomizing and tell to DHCP server dedicated to your server only ipv6 address provided by host for you.
