briefly, risolve is clobbering your $_ which is the default place to which you read the records from the DNS handle. $_ is a global variable so this self same $_ is then used as the key for your hash.

while (my $discard = <DNS>) {1}; # this would fix it

If risolve is intended to resolve the IP address of the hosts you can do this with pure Perl using gethostbyname. This will return a record that you will need to process to get human readable IP address, the linked docco explains how to do this.

Cheers,
