You have to return references to arrays and hashes. This is all
explained in the perlsub document.

perlsub also explains why you shouldn't use the Perl4 form of calling
subs anymore. Is there any reason you are not using perl's builtin
networking functions like gethostbyname() and gethostbyaddr()?
perldoc -f gethostbyaddr
perldoc -f gethostbyname
