Advanced Network Forensics
This web-based alternative to the Linux dig command provides an interface for webmasters to perform bulk DNS lookups, trace delegation chains, use custom resolvers, and validate deep network configurations.
DKIM Key Lookup
Select DKIM and enter your selector to retrieve and analyze the public key record at selector._domainkey.yourdomain.com, including key type, version, algorithm, hash method, and revocation status.
DNS Trace Mode
Simulate the DNS delegation chain from root zone to authoritative nameserver. Identify broken delegations and misconfigured NS records at every level.
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.
SPF & DMARC Analyzer
Deep analysis of SPF records counts all lookup-consuming mechanisms against the RFC 7208 limit of 10. DMARC analysis covers root policy, subdomain sp= policy, reporting addresses, alignment modes, and enforcement percentage.
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.
SRV Record Lookup
Query SRV records to inspect service discovery configurations — including priority, weight, port, and target host — used by VoIP, XMPP, Microsoft 365, and other services.
SOA Record Display
Every DNS query result now shows the SOA record from the authority section, identifying the primary nameserver, responsible contact, and zone serial number — matching the output of command-line dig.
Auto-Detect IPs
Paste an IP address into the box and hit Dig. We automatically detect it and switch the query to a Reverse IP (PTR) lookup to save you a click.
