So now I’m back to the DHCP setting.
I configured the DHCP server on my router to give anyone 2 IPv6
addresses: one that I configure with a static lease, and another one.
On the luci interface of my router, I see that the default mode for the
DHCP server is "stateful + stateless", which I guess translates to the
two addresses I get on the client machine. In fact, this is the
default, so I didn’t especially chose it that way.
If I keep the analogy, the "stateless" IP looks a lot like the
problematic IP I get in the static configuration.
I switch my DHCP server configuration to "stateful only", and now I
only have the static lease on the DHCP client configuration.
Let’s go back to the static networking configuration.
And now, the parasitic IP address is gone.
So, I guess there are 3 explanations:
1. That IP was committed to disk when I was running the DHCP
configuration, and got activated by default when I switched to the new
static configuration;
2. What guix considers a static client configuration talks to what
librecmc calls the DHCPv6 server and decides whether it’s OK to assign
a stateless IP depending on what the server says;
3. Some network stuff happens way above my understanding.
Anyway, I consider that problem solved for me.
Now I switch back to the DHCP configuration, otherwise the SMTP server
won’t start and I can’t send this email…
