This program consists of three files namely c.java,rs.java,ls.java

c.java-> It is a client side program .

ls.java-> It is a local server side program.

rs.java-> It is a root server side program.

Implementation: run c.java

then ls.java

then rs.java

Working:

Here c.java will given with the domain name as input and it will now search the domain name in local server (local.txt) if the domain name is not found in local server then it will move towards the root server (root.txt) where the domain name is available along with its IP address. and finally it gets printed.
