Netstat -Ano. What Does This Mean. .?

Getting an output that shows a specific process or group of processes (listed as PIDs) in netstat -ano.

The PIDs seem to be connecting to multiple 'Foreign Address' IPs, or perhaps trying to spam multiple foreign IPs. That's IF I'm interpreting the output correctly.

Here's an example of the outputs in question. Does the : output mean 'wildcard IP : wildcard port' ?

Therefore meaning those PIDs are trying to, or literally broadcasting on all IPs?

If so, how to stop them doing so?

Your assistance much appreciated.

Here's an example of what I mean:

PROTO  Local Address   Foreign Address PID
UDP    0.0.0.0:12345   *:*             2384
