I know that in order to join a group, i just insert the address, but
how will the server, or the other clients knows what is the IP address?

You either have to fix it in advance or use an address allocation
service such as the Multicast Address Dynamic Client Allocation Protocol
(MADCAP - see RFC 2730).
