1.2 Networking

Central to your computer being networked is the IP address of your machine. An IP address (Internet Protocol address) specifies the exact routing to an Internet host. When a name server is given a domain name, it resolves that name to an IP adress. An IP address typically consists of four numbers, e.g.
  137.205.192.34  
. You can think of the IP address as being analogous with a telephone number.

You can always find the IP address of a machine if you know the machine name, by using the
  host  
command.

Putting it into Practice:

In this exercise, you will find out the IP address of the machine that is the front-end to the CSC task farm. This machine is called argus.csc.warwick.ac.uk. Try typing at the prompt
  prompt> host argus.csc.warwick.ac.uk  
What is the IP address of argus.csc.warwick.ac.uk?
