Yes, that's correct. The system is a Raspberry Pi running Raspbian. It is
DHCP/DNS server (dnsmasq) for my LAN.

As said earlier, all information [for this type of system] points towards
setting the static address in /etc/dhcpcd.conf and apparently dhcpcd
handles this situation. At least, this has been working for several years
without problems. Until now, that is, thanks to some buggy(?) IoT devices.

I now have the static address setting in /etc/network/interfaces and
disabled dhcpcd so everything is fine again, and hopefully more robust.

Thanks all for your valuable feedback that helped me to find the problem
and its solution.
