255.255.255.255 is indeed the broadcast address. What is not working? 
Which Pd version? Which network objects? Broadcast works just fine for 
me with [netsend -u] in Pd 0.51 on Windows 7.

Note that broadcast/multicast can only be used for local networks. Also, 
for p2p communication over the internet you need

Shameless plug: The next (pre)release of "aoo" will allow sending 
arbitrary OSC messages over the internet. It has methods for sending 
messages to individual peers and also "broadcast" messages to all 
connected peers. Hopefully I manage to release it soon... It's way 
overdue :-/
