Dear Experts

i am trying to get the IP address returned by the API getaddrinfo(). i have no experience with Socket module but i found some code online and giving a try. i use the following code.

#!/usr/bin/perl
use Socket;

my $server = shift @ARGV;
my $pip = gethostbyname($server);
my $IP_add = inet_ntoa($pip);

print $IP_add;

[download]

this returns the IP address of the server passed as argument.

but when i try to print the value of $pip, it returns nothing and if i try to pass the $server directly instead of $pip it gives me error. i am not able to understand when $pip has nothing in it, it works but if i pass $server which has name of server in it it gives error.

could someone explain?
