DNS Lookup Tool
Check any domain's DNS records, including A, AAAA, CNAME, MX, NS, TXT, SOA and CAA, from two public resolvers at once. See whether a change has propagated and whether email security records are set up.

"Match" compares Google Public DNS and Cloudflare. A mismatch usually means a recent change is still propagating.

What is a DNS lookup?
DNS (the Domain Name System) translates domain names into the addresses and settings computers use. A DNS lookup shows a domain's records: where its website lives (A/AAAA), where its email goes (MX), its name servers (NS) and verification or security text (TXT).
Why do the two resolvers show different answers?
After you change a DNS record, resolvers around the world keep the old answer until its TTL (time to live) runs out. Different answers usually mean a change is still spreading. This is called DNS propagation and can take from minutes to 48 hours.
What are SPF and DMARC?
They are TXT records that protect your domain from email spoofing. SPF lists the servers allowed to send your email; DMARC tells receivers what to do with mail that fails the checks. Missing them can send your email to spam.
