 Dnsenum is a multithreaded perl script to enumerate DNS information of a
 domain and to discover non-contiguous ip blocks. The main purpose of Dnsenum
 is to gather as much information as possible about a domain. The program

   1) Get the host's addresses (A record).
   2) Get the namservers (threaded).
   3) Get the MX record (threaded).
   4) Perform axfr queries on nameservers and get BIND versions(threaded).
   5) Get extra names and subdomains via google scraping (google query =
      "allinurl: -www site:domain").
   6) Brute force subdomains from file, can also perform recursion on subdomain
      that have NS records (all threaded).
   7) Calculate C class domain network ranges and perform whois queries on them
      (threaded).
   8) Perform reverse lookups on netranges (C class or/and whois netranges)
      (threaded).
   9) Write to domain_ips.txt file ip-blocks.
