About ServerRecords

ServerRecords is a free DNS and email diagnostics toolbox. It lets you look up DNS records (including the DNSSEC family), check email authentication (SPF, DKIM, DMARC, BIMI, MTA-STS, TLSRPT), test mail servers over SMTP, inspect HTTPS connectivity and security headers, check blacklists, look up WHOIS registration and IP ownership, and generate SPF/DMARC records and strong passwords — all from one page, with plain explanations instead of raw technical output.

Pick a lookup type from the picklist, enter a domain or IP address, and run the look up. By default, DNS look ups return every record type at once, and the Email Health and Domain Health checks roll several look ups into a single scored report so you can see the full picture in one pass.

Your last 20 look ups on this device are kept in the History panel (a sidebar on desktop, an expandable panel on mobile) so you can revisit a previous result without looking it up again.

Every look up is performed live, on demand — using public DNS resolvers, a DNS-over-HTTPS service for DNSSEC-family records, RDAP and blacklist services, and by connecting directly to the domain you enter over HTTP(S) or SMTP where a check requires it. Nothing is scheduled, monitored, or stored on our servers. See the Privacy Policy for details.
