nslookup is a command which shows you your DNS and the I.P. domain translation. Yup.
Hosts is a file in both windows and linux operating systems that provides host name to I.P. translation. This is useless for the average user and would be annoying to mess with on multiple computers but if it's just one computer you could use it to redirect to another webpage.
All the other stuff in the chapter like NetBIOS takes place on Windows so I can't try it out here.
Thrilling post wasn't it?
