Neither gethostbyname nor gethostbyaddr make DNS requests (directly). They call the similarly named system calls. So not the right tools for multiple reasons.

Doing a quick search for DNS gives us Net::DNS. While it doesn't allow you to specify a server, it's just a means of accessing an instance of Net::DNS::Resolver which does allow you to specify a server.
