You can use teh LvlLord patch from <a href="http://www.lvllord.de/">here</a>. Be aware that it is technically a security risk to raise the number of connections allowed, hence the reason Microsoft reduced it to 10. Realistically, it isn't much of a risk.

An easy way to find an IP is to open a command prompt, and type "ping <site>" where <site> is the address of the site you need to resolve. It only works when you have good DNS servers though.
