Hi.

The player uses a standard routine to get its IP adress by default:
1. look for a DHCP server, if it finds one, it uses the supplied adress (if any)
2. if no DHCP server or no IP supplied, it uses uPNP to determine its IP
The non-default behaviour, which is setable via emplode, is a fixed IP of your coice. The IP that is used with uPNP is always 169.something, and it uses the very same algorithm to determin its IP as the MS OSes use (at least W98, W2k and above).
