I am testing the alpha 2 release of Debian 12
(I'm quite annoyed they have done away with /var/log/syslog)
My system is "pure" debian 12 and was net installed a few minutes before
my checks. Nothing was changed from the original install.
My problem today is identifying what bit of the system is getting the
IPv6 address. I can find nothing in journalctl
The networking is pure systemd networkd.service controlled
root@debian12:/etc/network# systemctl status networking
● networking.service - Raise network interfaces
Loaded: loaded (/lib/systemd/system/networking.service; enabled;

cat /etc.network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
allow-hotplug enp0s3
iface enp0s3 inet dhcp
# This is an autoconfigured IPv6 interface
iface enp0s3 inet6 auto
Checking dhclient I see
ps ax | grep dhcl
354 ? Ss 0:00 dhclient -4 -v -i -pf
/run/dhclient.enp0s3.pid -lf /var/lib/dhcp/dhclient.enp0s3.leases -I -df
/var/lib/dhcp/dhclient6.enp0s3.leases enp0s3
579 pts/0 S+ 0:00 grep dhcl
So no dhclient -6 running.

My question remains. What is getting the IPv6 address and how can I make
configuration changes if required?
