Frequently asked questions
What record types can this DNS record checker query?
The tool queries common DNS record types, including A (IPv4 addresses), AAAA (IPv6 addresses), CNAME (canonical names), MX (mail servers), TXT (text verification data), and NS (authoritative nameservers).
Why are my recent DNS updates not showing up in the results?
DNS changes depend on TTL (Time to Live) values and caching across intermediate resolvers. It can take anywhere from a few minutes to 48 hours for changes to fully propagate worldwide.
How can I verify email authentication records like SPF or DMARC?
Select the TXT record option and query your root domain or relevant subdomains (such as _dmarc.example.com). The output will display the plain-text policy strings configured for your domain.
Is the DNS record checker free to use?
Yes, the tool is completely free to use directly in your browser with no account creation or usage limits required for standard queries.
