Hello freebsd-hackers,
 I wrote a short program (on FreeBSD 6.0), that attempts
to call sendto() on a UDP socket, with 127.255.255.255 as
the destination address. It failed - with errno 49 (EADDRNOTAVAIL).
Setting SO_BROADCAST and IP_ONESBCAST did not help.

 After examining
- various RFC's,
- source code under /usr/src/sys/netinet/ and
- archives of freebsd-hackers & freebsd-net,
I have not been able to determine the reason.

 Is it possible to successfully sendto() on a UDP socket
with 127.255.255.255 as the destination address? If yes,
how can that be done.

Specific questions :
----------------------------------------------------------
- Is it correct to understand that 127.255.255.255 is the
 directed network broadcast address for net 127? If yes,
 which RFC specifies that?

- If not, is 127.255.255.255 considered to be a host
 address? If yes, which RFC specifies that?
----------------------------------------------------------

 Could you please help me understand this?


sincerely

Mathen
