I'm trying to solve this problem, but I'm not sure I have come to a good solution. Can you help me? I'll text the problem:
"Your boss ask you to realize a program to improve the DNS access. This program substitute the original support on the client and act in this way:
a) The program manage a list of 40 elements and each of them identify a name server;
b) Every time that is necessary to build a connection with a name server, the program try to connect with the first of that list. Shouldn't it give no answer, the program build a connection with the second one and so on;
c) The first of the list is an IP address written by the user during program configuration. All the others element are names of "reliable" name servers and can't be modified.
Explain if this program could be useful and, in case, which "plug-in" should it use".
I have tried to figure out the solution using DNS server replication, but I can't. Thank you in advance for your time.
