Solve : Tracing back an IP (the HTTP protocol fundamentals)? |
|
Answer» Hi. I've heard that you can always trace back an IP no MATTER what, because of the HTTP protocol. I don't understand how that's possible. Could someone explain it to me? Examples 1) If you are talking to someone on MSN, how can you get his IP without sending a file to him or having him visit an url which logs his IP? He's connected to the MSN server, so I don't get it. 2) Someone tries to ping you, but your router is set so that no one can? Now, I'm not a networking novice (I've STUDIED both datacommunication, networking, TCP/IP and assistant-networking, so that covers a lot, HOWEVER I forgot most of it) but still some people claim that an IP is tracable no matter what. If this is true, then BANKS would be hacked so fast, no? What about the following scenario: IP culprit -> proxy -> proxy -> 100.000 PC botnet -> proxy -> public network -> IP tracer How in the world could IP tracer possibly find the IP of IP culprit? Is it a matter of time/skill/tools? I've had the Federal POLICE come to my college and explain how nearly impossible it is to trace down guys like this. Not to mention that jurisdiction spans over several countries when the botnets are spread out all over the world.. it's almost mission impossible and 99% of the cases they don't bother anymore. What about: IP culprit -> router -> public network -> router -> IP tracer How can tracer find out culprit's IP if culprit's router is set to forbid ping/tracing? What if he is behind a proxy that doesn't allow tracer to do any form of tracing? I just don't get how you can always get someone's IP, supposedly because the HTTP protocol always allows it. I don't get it. lol Someone care to explain? Thank you. Treval Seems like my question is too hard. |
