About fucking time... Android finally doing proper DHCPv6. When this is live on my phone I can turn off SLAAC, and not have Windows insist on using it (yes, there's meant to be ways to stop Windows from using SLAAC, so it only uses DHCPv6, but I never saw any of them work). *I* don't want 'random' addresses, I want predictable ones for firewalling and ACLs: https://android-developers.googleblog.com/2025/09/simplifying-advanced-networking-with.html?m=1

#ipv6 #android #slaac #dhcpv6

IP address in #Debian #trixie not what you expected?

Edit /etc/dhcpcd.conf and look for the block “Generate SLAAC address” near the end; comment out slaac private and uncomment slaac hwaddr.

Service:

Hin und wieder wird bei DYNDNS eine stabile Host-ID verlangt:

Linux allgemein:
man ip-token
ip token set ::3000 dev eth0
oder im NetworkManager:
https://networkmanager.pages.freedesktop.org/NetworkManager/NetworkManager/nm-settings-nmcli.html

[ipv6]
addr-gen-mode=eui64
method=auto
token=::3333

Damit kommt man ohne DHCPv6 aus und die Hosts müssen nicht ihre MAC-Adresse "verraten".

Wenn jemand die äquivalenten Einstellungen für andere OS oder Tools kennt, kann ja gern damit darauf antworten.

Does anyone know how to make Windows 11 prefer #DHCPv6 over #SLAAC?
