Zone Transfer Tester

Test for unauthorized DNS zone transfer (AXFR) vulnerabilities. Ensure your DNS servers are properly secured against information disclosure.

Zone Transfer Test
Enter a domain name to test its nameservers for zone transfer vulnerabilities

Enter a domain name without protocol (e.g., example.com, not https://example.com)

What is a Zone Transfer Vulnerability?

DNS Zone Transfer (AXFR) is a mechanism for replicating DNS records across multiple DNS servers. When improperly configured, it can allow unauthorized users to download a complete copy of a domain's DNS records, potentially exposing sensitive information about the network infrastructure.

This tool tests if your domain's nameservers allow unauthorized zone transfers, which is considered a security vulnerability.
