Suppose within a web page displayed on your Web browser you click on a hyperlink which leads to another web page. The IP address for the new URL is not cached in your local DNS server (AKA local name server), so a DNS lookup is necessary to obtain the IP address before retrieving the web page. Suppose that in total three DNS servers are visited before your host finally receives the IP address from the local DNS server. The first DNS server visited is the local name server, with an RTT delay of RTT 3 msecs. The second and third DNS servers contacted by the local name server have RTTs of RTT,40 msecs and RTT: 20 msecs The requested Web page contains a base HTML page and no objects. The time to send an HTTP request to the Web Server hosting the webpage and receive a response is RTTIT and is equal to 60msec. In other words, it takes 60msecs for the Client to fetch the web page from the web server. (Note: RTT Round Trip Time the time to send request and receive a response -indlusive,both directions RTT RTT local DINS cache dient With respect to the above information, answer the following questions: a List in words each step in the DNS resolution (find out the IP Address) b. How much time in total is spent on the DNS query (show your numbers)? c Once the IP Address is received at the Client, what can the Client do now? d.
