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.
Ethical Usage Notice
This tool is intended for legitimate security testing and domain management purposes. Only use it on domains you own or have permission to test. Unauthorized testing may violate terms of service or laws in some jurisdictions.
