Nope, I haven't looked at it yet and of course you're welcome to hack away. :)

Off the top of my head here are some of the things that might need doing:

* Give each request a pointer to the domain to use ("in-addr.arpa" or
  "origin.asn.cymru.org" or whatever) and make put_dns_packet_on_wire()
  use this.

* Don't forget it's a TXT record! The current rDNS always uses 12 (PTR).
  read_evt_handler() checks this in a packet and decides what to do with it.

* Figuring out way to input and output it best might be tricky! I suspect more
  fields should be added to the Target class and the nmap_mass_rdns()
  interface will have to be modified... What about something so it's
  easy to customise exactly which types of lookups to do with
  nmap_mass_rdns()? Something like


#define MASS_RDNS_DNS 1
#define MASS_RDNS_ASN 2
...

nmap_mass_rdns(targs, num_targs, MASS_RDNS_DNS|MASS_RDNS_ASN);



Sounds like a fun project!

Best of luck,

Doug
