I tried the netstat command in DOS . I am hoverver confused about the various parts of it . Theres a person who keeps buggig me online (MSN) and i want to trace him. I however dont know his IP address. here is what i get when i type netstat on my comp : Code: TCP AMD:3502 baym-cs209.msgr.hotmail.com:1863 This i think corresponds to the incomming trafin on MSN. so i tried to tracert this particular host and this is what i get : Code: Tracing route to baym-cs209.msgr.hotmail.com over a maximum of 30 hops: and then i get a series of hosts and IP address . HOw do i decide which one is his . i can identify mine and one of it was the MSN server i guess , cuz its location reported as Washigton ,USA. If someone could help me i would be grateful.
