why not simply let the applet send it's ip address via udp?

That was my first attempt but unfortunately it doesn't work :

• Most browsers' Java VMs don't allow untrusted applets to learn

it's IP address for security reasons.

• Even if the applet could send the client machine's IP, if

that machine belongs to a network that uses private Ips (i.e., is behind a firewall/NAT machine) it would be useless...

So what I really need is to learn the address from the point of view of the destination (PD).

[netserver] does the job but only for TCP connections but UDP is more suited in my case.

Hi all,

Is there an object like [netserver] that prints the client's IP address, but that is able to receive UDP connections?

I'm trying to connect an applet to PD using netreceive but since I need to send data back to the applet I must know it's IP...
