Find out about an IP address that is well known to you, such as that of your college or your work server. Set up an experiment in which you look up the domain name for this IP address.  Consider DNS servers.

 (a) Compare two approaches, obtaining a name from a file in a remote machine and from a DNS server of the local ISP.

(b) Describe the relationship between a domain name taken from a DNS server and an IP address subnet.

(c) In part (b), do all hosts on the same subnet need to be identified by the same DNS server? Why?
