About this tool
Free DNS propagation checker. Compare how major public resolvers answer for your domain so you can confirm a DNS change has gone live.
Frequently asked questions
How do you check propagation?
We ask several independent public resolvers the same query and compare their answers.
Is a mismatch a problem?
Temporary mismatches are normal while caches expire; consistent matches mean the change is live.
Which record types are supported?
A, AAAA, CNAME, MX, TXT, NS and more.
