Server Type and response code are part of the headers the webserver returns for every http request it receives. These can easily be obtained from the HTTP response object, see the LWP docs for details.

Blacklist Status is probably obtained by querying an external service. There are lots of blacklists for various purposes, perhaps most notably spam blacklists e.g. Spamhaus. There are Perl modules available for querying such services, search CPAN.

As for the rest, nothing jumps immediately to mind, although it shouldn't be that hard to find.
