DigInterface Tools од Jaco

DigInterface Tools brings the DNS, email, and network utilities from diginterface.com straight into your browser toolbar — no need to open a new tab for a quick lookup.

What it does:
- DNS Lookup — query A, AAAA, MX, NS, CNAME, TXT, SOA, PTR, SRV, CAA, SPF, DKIM, and DMARC records for any domain
- Email Header Analyser — paste raw email headers to see SPF/DKIM/DMARC/ARC authentication results and relay hop timing at a glance
- SSL Checker — certificate expiry, issuer, SANs, and TLS version for any domain
- Blacklist Checker — check a domain or IP against 15+ major DNSBL/RBL lists
- WHOIS Lookup — domain registration or IP/ASN ownership details
- SPF Expander — flatten an SPF record into its resolved IP ranges and see your DNS lookup count
- DNS Propagation — check how a DNS change has propagated across public resolvers worldwide

Right-click, anywhere: Select a domain or IP on any page and look it up instantly. Select raw email headers and analyse them without leaving the page. Right-click a link to check where it actually points before you click it. Right-click any page to check its domain.

Requires a free DigInterface account and API key (takes under a minute to set up) — generate one from your account dashboard with the dns and email scopes.
