Our fictitious zone serves a college. Movie University studies all aspects of the film industry and researches novel ways to distribute films. One of our most promising projects is research into using IP as a distribution medium. After visiting our registrar's web site, we have decided on the domain name movie.edu. A recent grant has enabled us to connect to the Internet.
Movie U. currently has two Ethernets, and we have plans for another network or two. The Ethernets have network addresses 192.249.249/24 and 192.253.253/24. A portion of our host table contains the following entries:
127.0.0.1 localhost # These are our killer machines. 220.127.116.11 robocop.movie.edu robocop 18.104.22.168 terminator.movie.edu terminator bigt 22.214.171.124 diehard.movie.edu diehard dh # These machines are in horror(ible) shape and will be replaced # soon. 126.96.36.199 misery.movie.edu misery 188.8.131.52 shining.movie.edu shining 184.108.40.206 carrie.movie.edu carrie # A wormhole is a fictitious phenomenon that instantly transports # space travelers over long distances and is not known to be # stable.
