Dig Toolbox is a free online tool for inspecting the DNS and email setup of any domain, website, or email address. Paste a URL, hostname, or email address and it resolves the records for you — no sign-up, and nothing is stored.
Look up A, AAAA, CNAME, MX, TXT, NS, SOA, CAA, SRV, DS / DNSKEY, HTTPS / SVCB and more, with TTLs and DNSSEC validation status.
Check SPF, DKIM, DMARC, MX, MTA-STS and BIMI together to see whether a domain is configured to send and receive mail securely.
Identify the hosting provider, network (ASN), owner and country behind any IPv4 or IPv6 address from its PTR and routing data.
See domain registration details — registrar, creation and expiry dates, nameservers and status — over RDAP with a WHOIS fallback.
