Normally, radio-broadcasters have the streaming-servers not at home. They rent an external SERVER with an amount of listeners, and feed it from home-pc using (free) radio-broadcaster-CLIENT software.
If the "feeder" plays music with copyrights, HE has to pay for it, and NOT the server-farm-company!
In most countries the copyright-authorities offer plans for an amount of listeners. (For example, in Western Europe the yearly costs for 100 listeners are higher, than in Eastern Europe)
There are two possibilities:
1.) You want to pay
2.) You want not to pay
1.) You want to pay
The easiest way is to buy a plan in your own country.
But I know someone, who has good friends in a country with very cheap copyright-plans. So he lets one of his friends pay for the copyright-songs. He uses an IP fom this country to feed the streaming-server. This works for years, and he saves over 400 Euros a year!
2.) You want not to pay
Of course, you can use your own IP for your illegal radio-stream, and if you are lucky, nothing will happen.
But I can not recommend this!
If they find out, you have to pay THOUSANDS for punishment!
So NEVER use your own IP-address doing this!
There are some countries in the world ANYONE cares about ANY copyright. And if an authority asks for the real user of an IP, they get no answer! (Nigeria for example, but working IPs for a longer time are hard to find)
Hiding own IP-address is no secret. You can use a proxy, SSH-shell or VPN.
But be careful! Some streaming-programs are spys. They steal your personal data and it's not possible beeing anonymous using them.
A good anonymity-checker is this one:
Take a look at the last line called "Unsecure Headers".
If your real IP is shown here, you are not anonymous!
