Frequently Asked Questions
What is DNS enumeration?
DNS enumeration is gathering information from DNS records, such as hosts, mail servers, and subdomains, to map a target's infrastructure during reconnaissance.
What is a DNS zone transfer?
A zone transfer copies all records from a DNS server to another. If a server allows it to anyone, an attacker can download the full list of hostnames, which is a misconfiguration.
Which tools are used for DNS enumeration?
Common tools include dnsrecon, dnsx, dig, and subdomain finders. This free, hands-on Codelivly room shows how to use them to uncover hidden infrastructure.
