Dear monks,

I want to find whether the given ipaddress/hostname is present in the network.

I've tried the gethostbyname and when I give unavailable hostname, it is returning undef, but when I give unavailable ip address, it is returning the same IP.

use Socket;

$packed_ip = gethostbyname shift;

if (defined $packed_ip) {
    $ip_address = inet_ntoa($packed_ip);
    print $ip_address;
}
else {
    print "Host not exist\n";
}
