Indeed:

Aug 01 00:20:15 BaseKit systemd-networkd[434]: eth0            : removed address: 192.168.51.144/24 (valid for 0)
Aug 01 00:20:15 BaseKit systemd-timesyncd[346]: Network configuration changed, trying to establish connection.
Aug 01 00:20:15 BaseKit systemd-networkd[434]: eth0            : added address: 192.168.51.145/24 (valid for 9min 30s)
Aug 01 00:20:15 BaseKit systemd-timesyncd[346]: Network configuration changed, trying to establish connection.

I'm not sure, why the new address is found again though.

Note: this is with "net.ipv4.conf.all.promote_secondaries = 1".  Setting
just "net.ipv4.conf.default.promote_secondaries = 1", as it's currently
done in /usr/lib/sysctl.d/50-default.conf is not always sufficient. I think
the default only works for new interfaces that show up afterwards.
