DigInterface Tools

DNS lookup, email header analysis, SSL, blacklist, WHOIS, SPF & propagation checks — right from your toolbar.

DigInterface Tools brings the full DigInterface.com toolkit into your browser — no tab-switching, no copy-pasting URLs. 🔍 WHAT IT DOES Click the toolbar icon or right-click any selected text to instantly run: • DNS Lookup — query A, AAAA, MX, NS, CNAME, TXT, SOA, PTR, SRV, CAA, SPF, DKIM and DMARC records. Select ALL to run every record type at once. • Email Header Analyser — paste raw email headers (or right-click selected headers on any page) to get SPF, DKIM, DMARC and ARC authentication results, relay hop timings, and a full parsed header breakdown. • SSL Checker — instantly see certificate validity, days remaining, issuer, TLS version and SANs for any domain. • Blacklist Checker — check whether a domain or IP address is listed on major DNS blacklists. • WHOIS Lookup — domain registration details or IP/ASN information. • SPF Expander — expand nested SPF includes to see all authorised IP ranges and DNS lookup count. • DNS Propagation — check how far a DNS change has propagated across global resolvers. ⚡ GETTING STARTED 1.
