It’s easy for a hacker to know what a network looks like once they get onto a network. Almost all computers have simple tools that can be used to fill in some of the blanks hackers would need in order to perform different attacks.

Using ping, ipconfig/ifconfig, traceroute and nslookup, answer the following questions. Your computer should be connected to the Internet either via a wired or a wireless connection. To receive full credit, you must paste a screenshot of the tool you used to answer each question.
