Internet Worm IP Scanning Programming

Internet Worms' most important feature is the ability to scan for more vulnerable machines. The first part of the scan is to generate a victim IP address - this can be done through a variety of scanning techniques. A good listing is available in the "scanning section" of this paper. This 2 part video series will discuss the programming of a Sequential, Subnet and Random IP address generator. In this video tutorial we will focus on the Random Scanning pattern - which is simply to generate a random IP address and try to infect it. As the Internet has large chunks of unallocated IP addresses this technique definitely has a lot of drawbacks, but most worms use it.
