It won't be broadcast, but it is in my /etc/hosts at my workstation,
and if needed easily copied to other things / computers.
I do most things with raspies via ssh from one big PC anyways.
One raspi has an analog output that is fed to a security recorder that I can
then see
via ethernet on the main PC..
There is an other reason for fixed IPs on that machine,
do not know if you are familiar with 'snort',
I use if for traffic monitoring.
As a hundred different things communicate with the main station,
say if I want just to see the thing my browser does, but not all the packets
from cameras (that is a LOT of traffic, or raspies),
there is a script like this:
snort -i eth0 -v -d not host camera4 and not camera6 and not 192.168.178.1 and
not 192.168.178.84 and not 192.168.178.79 and not 192.168.178.82

I just type
trace-net3

There are a thousand more commands / scripts.
ha, I just finished ip_to_country C code that uses successive approximation,
even on a fully loaded raspi it finds a country from an IP in a split second!
A linear search in the same database takes several seconds.
Now it is more useful in a real time script to kill bad actors.
