DNS lookup & propagation
Enter a domain and record type and the tool queries two independent DNS resolvers (Cloudflare and Google) simultaneously. Matching answers mean the change has propagated, while differing ones mean DNS is still spreading.
What each record type does
A/AAAA point to the website’s IP, CNAME aliases another name, MX defines mail servers, TXT carries verifications and policies (SPF, DKIM, which you can check here) and NS says who manages the domain.
How long DNS propagation takes
After a change, resolvers worldwide keep the old value for the TTL, typically minutes to hours, up to a day for NS changes. That is exactly what this tool shows: when independent resolvers agree, you are propagated. Moving your site to the EU? See the ordering walkthrough.
Frequently asked questions
I changed DNS but my site still loads from the old host. Why?
Your resolver (or browser) holds the old value for the TTL. Check the record with this tool. If the three big resolvers already return the new value, it is just local cache, and restarting the browser or waiting helps.
What is the TTL shown next to answers?
Time To Live, meaning how many seconds a resolver may cache the answer. Before a planned DNS change, lower the TTL a day ahead so the change spreads faster.
Why do resolvers return different answers?
Most often a change is still propagating. A persistent difference can mean geographically varied answers (GeoDNS/CDN), which is normal for large services.
