About this tool
Look up the DNS records for any domain. Choose a single record type or ALL to query A, AAAA, CNAME, MX, NS, TXT, SOA and CAA at once. Queries use DNS-over-HTTPS through Cloudflare's public resolver, so results reflect what a major public resolver currently sees, including each record's TTL (how long it may be cached). Only record types that exist for the domain are shown.
How to use it
- Enter a domain, for example example.com.
- Pick a record type, or leave it on ALL.
- Press Look up DNS.
- Read each record type and its TTL.
Common problems
- No records found
- Check the spelling and that the domain is registered and has DNS configured. Some record types simply do not exist for a domain (for example no MX if it does not receive email).
- Results differ from what you configured
- Recent changes can take time to propagate because of TTL caching. Try again later, or use the DNS propagation check to compare resolvers.
- MX shows "0 ."
- That is a "null MX": the domain says it does not accept email.
