Frequently Asked Questions

DNS changes take time to propagate, sometimes up to 24-48 hours, since resolvers around the world cache records based on their TTL (time to live) value. This tool queries Cloudflare's resolver directly, but that resolver may still be serving a cached answer until the TTL expires.

An A record points a domain to an IPv4 address, while an AAAA record points it to an IPv6 address. Many domains have both, since not every visitor's network supports IPv6.

Yes — MX records show your mail servers and their priority, while TXT records commonly hold SPF, DKIM and domain verification values. This is exactly what mail providers check when diagnosing deliverability issues.
