FAQ
DNS Lookup questions.
What are DNS records?
DNS records map a domain to the servers behind it. A and AAAA point to IP addresses, MX to mail servers, TXT to verification and SPF records, NS to nameservers and CNAME to aliases.
How long does DNS propagation take?
Changes can take from a few minutes up to 48 hours to propagate, depending on the record's TTL and caching along the way. Checking the live records here shows what public resolvers currently return.
Why does DNS matter for SEO?
DNS controls where your domain resolves and how email authenticates. Broken records cause downtime, lost email deliverability and failed site migrations, all of which damage rankings and trust.
Where does the lookup data come from?
Queries are resolved over DNS-over-HTTPS through a major public resolver. The tool only resolves the domain name you enter and never connects to arbitrary URLs.
