# Performing DNS Enumeration and Zone Transfer
## When to Use
- Mapping the external attack surface of a target organization during authorized penetration tests
- Discovering hidden subdomains, internal hostnames, and IP addresses exposed via DNS records
- Testing whether DNS servers allow unauthorized zone transfers that leak the entire zone file
- Identifying mail servers, name servers, and service records for further targeted testing
- Validating DNS security configurations including DNSSEC, SPF, DKIM, and DMARC
**Do not use** against domains you do not have authorization to test, for DNS amplification or reflection attacks, or to overwhelm DNS servers with excessive query volumes.
## Most Often Missed & How to Confirm
- **Every nameserver, not just the first:** AXFR is often refused on ns1 but allowed on a forgotten secondary. Loop `dig AXFR example.com @<ns>` over *all* NS records before calling zone transfer "blocked."
