DNSRecon – DNS Enumeration Script
DNSRecon is a Python based DNS enumeration script designed to help you audit your DNS security and configuration as part of information gathering stage of a pen-test. DNS reconnaissance is an important step when mapping out domain resources, sub-domains, e-mail servers and so on and can often lead to you finding an old DNS entry pointing to an unmaintained, insecure server.

It’s also considered passive information gathering, as it’s a way to gather a map of company/target resources without alerting IDS/IPS systems by doing active probes/scans.


DNSRecon provides the ability to perform:

  • Check all NS Records for Zone Transfers
  • Enumerate General DNS Records for a given Domain (MX, SOA, NS, A, AAAA, SPF and TXT)
  • Perform common SRV Record Enumeration. Top Level Domain (TLD) Expansion
  • Check for Wildcard Resolution
  • Brute Force subdomain and host A and AAAA records given a domain and a wordlist
  • Perform a PTR Record lookup for a given IP Range or CIDR
  • Check a DNS Server Cached records for A, AAAA and CNAME Records provided a list of host records in a text file to check
  • Enumerate Common mDNS records in the Local Network Enumerate Hosts and Subdomains using Google
