Ever wanted to get someones IP adress from an MSN converstion? Its easy!
Simply send them a file over 1024kb (1mb). I recommend an MP3 as those arnt suspicious and are ussually over 1mb. Now go to the command line (Start > Run > cmd) and type 'netstat' (no quotes) then press enter. You will see a list of IP's connected to your computer like this one
C:\Documents and Settings\Jonny>netstat

TCP upstairs:1223 localhost:1224 ESTABLISHED

TCP upstairs:2290 26-277-134-148.dhcp.aldl.mi.charter.com:4274 SYN_SENT
Alright now look under the state colum for SYN_SENT the matching IP is the IP of the person you sent the file to! you may get the IP or their name server. You should be able to find out the IP/nameserver from all those DNS stuff websites and Nmap.
Well thats that! thanks for reading, hope its useful!
