What is DNSenum?

DNSenum is a versatile DNS enumeration tool used primarily for information gathering during security assessments and penetration testing. It is written in Perl and provides capabilities for enumerating DNS information such as hostnames, subdomains, DNS records, and zone transfers. DNSenum automates the process of querying DNS servers to collect valuable intelligence about a target domain's infrastructure.

Common Use and Commands

DNSenum is commonly used for:

• DNS Enumeration: Gathering information about a target domain's DNS infrastructure, including subdomains, hostnames, and associated IP addresses.
• Zone Transfers: Attempting zone transfers to retrieve all DNS records for a domain, which can reveal sensitive information about the target's network topology.
• Brute-Force Enumeration: Performing brute-force DNS enumeration to discover additional subdomains and hostnames.

The following are some common commands used with DNSenum:

dnsenum <domain>     ---> To perform a basic DNS enumeration
dnsenum -f <domain>  ---> For more advanced enumeration and zone transfer attempts
