DNS Lookup
Query DNS records for any domain — A, AAAA, CNAME, MX, TXT, NS, and SOA records.
A DNS lookup queries the Domain Name System to reveal the records that tell the internet how to reach a domain. Enter a domain, pick a record type, and fetch its A, AAAA, CNAME, MX, TXT, NS, or SOA records live from Cloudflare's resolver over DNS-over-HTTPS. It shows what public resolvers see right now — handy for debugging email, hosting, and DNS changes.
Frequently asked questions
What is a DNS record?
A DNS record is an entry in a domain’s zone that maps the name to information — an IP address (A or AAAA), a mail server (MX), text data (TXT), or another name (CNAME). Resolvers read these records to route traffic and services.
What is the difference between A and AAAA records?
An A record points a hostname to an IPv4 address such as 93.184.216.34, while an AAAA record points it to an IPv6 address. A domain can publish both so clients on either protocol can connect.
Why do MX records have numbers?
The number is a priority. Mail is delivered to the MX host with the lowest value first, and higher-numbered servers act as backups; equal values share the load.
How long do DNS changes take to propagate?
Propagation is bounded by each record’s TTL (time to live) plus resolver caching — usually minutes to a few hours, and occasionally up to 48 hours for records with long TTLs.
Why did a lookup return no records?
Either that record type does not exist for the domain, or the name is misspelled. Try a different record type, or confirm the domain resolves at all with an A or NS query.
