If you work in penetration testing, digital forensics, or security auditing, you’ve probably heard about dnsenum - a powerful multithreaded tool used to gather DNS information and map out domain network ranges. It’s one of the most useful utilities for discovering subdomains, DNS records, IP blocks, and more.
followed by installation steps for multiple Linux distributions.
What Is dnsenum?
Dnsenum is a multithreaded Perl script designed to extract as much DNS information as possible from a target domain. It automates the process of DNS enumeration and helps identify non-contiguous IP blocks, related hosts, and domain structures - making it a valuable tool for ethical hackers and security researchers.
Key Features of dnsenum
Dnsenum currently performs the following operations:

Dnsenum currently performs the following operations:- Retrieve host addresses (A records).
- Identify nameservers (threaded).
- Extract MX records (threaded).
- Perform AXFR zone transfer attempts and collect BIND versions (threaded).
- Discover extra names and subdomains using Google scraping
("allinurl: -www site:domain"). - Brute force subdomains from a wordlist, with recursive checks for subdomains that have NS records (threaded).
- Calculate C-class network ranges and run WHOIS queries on them (threaded).
- Perform reverse DNS lookups on netranges (threaded).
- Save all discovered IP ranges to domain_ips.txt.
