Website records
A and AAAA point to IPv4 and IPv6 addresses. CNAME aliases one hostname to another. NS and SOA describe delegation and zone authority.
Live recursive DNS observation
DNS Checker
Enter a domain to inspect its current public DNS records. The result URL keeps the domain, so you can send the same live checker link to a customer or colleague.
What this result means
A current resolver view, not saved history.
Each link runs a fresh lookup when opened. OriginDiff does not save a public snapshot, publish recent searches, or claim that one resolver represents DNS propagation everywhere.
Mail and policy records
MX lists mail exchangers and their priorities. TXT commonly carries SPF, verification and other policy data. CAA limits which certificate authorities may issue certificates.
TTL and timing
TTL is the remaining cache lifetime reported in this answer, not a guaranteed global update timer. Recheck later when you are waiting for DNS changes to become visible.
The checker uses RFC 8484 DNS-over-HTTPS wire format and names its recursive resolver. DNS Propagation will later compare explicitly identified locations and providers as a separate tool.
