4.1 Our Zone
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
involves research into using IP as a film 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 to add
another network or two. The Ethernets have network numbers
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
192.249.249.2 robocop.movie.edu robocop
192.249.249.3 terminator.movie.edu terminator bigt
192.249.249.4 diehard.movie.edu diehard dh
# These machines are in horror(ible) shape and will be replaced
# soon.
192.253.253.2 misery.movie.edu misery
192.253.253.3 shining.movie.edu shining
192.253.253.4 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. The only difference between wormholes and routers is
# that routers don't transport packets as instantly--especially
# ours.
192.249.249.1 wormhole.movie.edu wormhole wh wh249
192.253.253.1 wormhole.movie.edu wormhole wh wh253
And the network is pictured in Figure 4-1.
