Net-DNS-Extlang This module implements the DNS extension language described in this draft: https://datatracker.ietf.org/doc/draft-levine-dnsextlang/ INSTALLATION To install this module, run the following commands: perl Makefile.PL make make test make install USE WITH Net::DNS While Net::DNS::Extlang can load rrtype descriptions from either a text file or the DNS, when invoked automatically by Net::DNS to handle an unknown rrtype it only reads from the DNS. The dnsextlang draft proposes that rrtype data is stored in the DNS at {rrname,rrtype}.arpa. That is the default in Net::DNS since version 1.07. Until the IETF approves this and puts the info at that location, you'll have to set the DNS location yourself by setting $DNSEXTLANG in Net::DNS::Parameters. For the time being, the author has put rrtype data at {rrname,rrtype}.services.net, so you can put this in your program after you include Net::DNS $Net::DNS::Parameters::DNSEXTLANG = 'services.net.'; Once you've done that, the intention is that new rrtypes installed on the fly work just like the ones built into Net::DNS. The first time Net::DNS sees an unknown RR type or number, it creates code on the fly to handle the type. Rather than loading Net::DNS::Extlang and its type compiler into the process that's using Net::DNS, when Net::DNS sees an unknown rrname or rrtype, looks up the name or type itself in the DNS lookup to find the description and then passes the description to the external program RRTYPEgen, which compiles the description into a perl module Net::DNS::RR::. Net::DNS loads the compiled module, and uses it the same way it uses a built-in RR module.
