Simulating a DNS scenario in Linux?

[oslon]

The computer science department at purdue university chose to place the following type A resource record entry in its domain name server.

localhost.cs.purdue.edu 127.0.0.1

Explain what will happen if a remote site tries to ping a machine with domain name

localhost.cs.purdue.edu

.

How do I simulate this in linux?

My guess:

- Go to machine 1's /etc/hosts and type

localhost.cs.purdue.edu 127.0.0.1

- Go to machine 2's /etc/hosts and type

localhost.cs.purdue.edu 127.0.0.1

Then do ping from machine 2.
But I don't think this is the correct way of replicating the scenario in question above. HELP.

ik this looks so close like homework. But I am just trying to re-learn computer engineering concepts.
