and range of ip address may 127.0.0.1 127.1.4.80.

i beginner , know should use inetaddress type express ip address. don't know how iterate inetaddress objects.

could me?

thanks lot!!

you need:

  1. a datagramsocket.
  2. some data in byte[] array.
  3. a target address:port, expressed inetsocketaddress.
  4. a datagrampacket, created byte[] array , target address.
  5. datagramsocket.send().

you can't use 127. if want talk other hosts. addresses localhost-only.
