Advanced Network Forensics
This web-based alternative to the Linux dig command provides an interface for webmasters to perform bulk DNS lookups, simulate zone walks, use custom resolvers, and validate deep network configurations.
1-Click Domain Audit
Instantly scan your domain's A, MX, SPF, DMARC, and DNSSEC records to receive a comprehensive health grade and identify security vulnerabilities in seconds.
Advanced Email Security
Verify modern email standards. Analyze DKIM keys, perform accurate recursive SPF lookups, inspect DMARC organizational fallback policies, and validate BIMI, MTA-STS, and TLS-RPT configurations.
Simulated Zone Walk
Step through the DNS hierarchy from the root zone down to the authoritative nameserver via a recursive resolver to identify misconfigured NS delegations.
Global Propagation
Verify worldwide DNS resolution instantly across 8 global resolvers including Cloudflare, Google, Quad9, AdGuard, OpenDNS, NextDNS, and ControlD.
Spamhaus Blacklist (DNSBL)
Select the DNSBL tool to instantly check if an IP or Domain has been globally blacklisted for sending spam or hosting malware.
BGP & ASN Info
Curious who owns an IP address? Use our ASN lookup to extract the network owner, CIDR subnet, country, and registry details using Team Cymru's database.
Custom Resolver
Enter any resolver IP (like 8.8.8.8) or DoH URL to query DNS through a specific nameserver — ideal for testing authoritative responses before propagation completes.
SOA Record Display
Every standard query result extracts the SOA record from the authority section, identifying the primary nameserver, responsible contact, and zone serial number.
Auto-Detect & IDN
Paste an IP address to automatically trigger a PTR lookup, or paste an Internationalized Domain Name (e.g. münchen.de) to automatically resolve via Punycode.
