Okay, I can't resist to ignore the "reasonable" question.

If I understand the "problem" correct, than has the original poster
TFTP clients that are shouting all over the Local Area Network
for a server to honour their demand. But the yelling (shouting)
is called "broadcast". And stupid^Wsimple clients will allways exists,
so it is up to the server the serve the screamers.

There are TFTP server that do answer "broadcasting" clients,
but that doesn't help tftpd-hpa (afterall we are on the tftpd-hpa ML ).

Early versions of DHCP programms were needing the IP-address (I don't remember which side (server or clientsss))

I suggest to setup the TFTP server with that broadcast address,
to find out if does help to serve the screaming TFTP clients.

Looking forward to hear something back
(thank you for listening to my rant :-)
