DNS Lookup

DNS records, global propagation across 20 servers, IP geolocation

What is DNS Lookup?

DNS (Domain Name System) translates domain names into IP addresses. Our DNS Lookup checks the complete record configuration for any domain, including A, AAAA, MX, NS, TXT, CNAME and SOA records.

DNS Propagation

After changing DNS records, the update must propagate to DNS servers worldwide. This test checks 20 global servers and shows on a map which ones return current results. Full propagation can take up to 48h.

SPF, DKIM, DMARC

Three email authentication mechanisms that protect against spoofing and improve deliverability. Grade A+ means all three are correctly configured.
