I have a job where I need to do nslookup on an IP address. If it matches then I need to print the name of the host. The problem is that the IP address comes reversed when ruing the command.
nslookup 10.11.12.13
13.12.11.10.in-addr.arpa
I tried to use reverse but that reversed everything which is not what I want.
my $ip = '13.12.11.10';
$result = reverse($ip);
print $result;
which then prints 01.11.21.31
I do not want to reverse everything, just the full numbers.
Please can someone help?
