❓ Frequently Asked Questions
What DNS record types can I look up? ▾
You can look up A, AAAA, CNAME, MX, NS, TXT, and SOA records. A records map domains to IPv4 addresses, AAAA to IPv6, MX for mail servers, NS for nameservers, and TXT for verification strings.
Why do DNS changes take time to propagate? ▾
DNS records have a TTL (Time To Live) value. Until that time expires, old records are cached by resolvers worldwide. Changes typically propagate within 1-48 hours depending on TTL settings.
Is this tool querying live DNS? ▾
Yes — this tool queries Cloudflare's public DNS resolver (1.1.1.1) in real time, so results reflect the current live DNS state for the domain.
