IP Spoofing is the creation of TCP/IP packets using somebody else's IP address. A technique of connecting to a web site and reporting an IP address different than the one you are actually connected too. Routers use the "destination IP" address in order to forward packets through the Internet, but ignore the "source IP" address. That address is only used by the destination machine when it responds back to the source.

Following are some example of IP Spoofing:

• Routing redirect - redirects routing information from the original host to the hacker's host.


• Source routing - redirects indvidual packets by hackers host.


• Blind spoofing - predicts responses from a host, allowing commands to be sent, but can't get immediate feedback.


• Flooding - flood fills up receive queue from random source addresses; smurf/fraggle spoofs victims address, causing everyong respond to the victim.
