Looking for a DNS Checker alternative?
DNS Checker shows you whether a DNS record has propagated globally. DNSSnuff checks whether your DNS is correctly configured. Different tools. Different problems.
Solves a propagation problem.
Shows you whether a specific DNS record (A, MX, TXT, etc.) has propagated to resolvers in different countries. Useful after making a DNS change and wanting to confirm it's visible globally.
Solves a configuration problem.
Checks whether your DNS is correctly configured — not just whether it's propagated, but whether what's propagated is right. 72 checks across everything that matters.
