What Is Authoritative vs Public DNS?
When you update DNS records at your hosting provider, those changes first appear on the authoritative nameserver — the server that holds the master copy of your domain's DNS zone. Public DNS resolvers like Cloudflare (1.1.1.1) and Google (8.8.8.8) then cache and serve these records to end users.
This tool queries the Hosting.com authoritative DNS server directly, then compares those results with what Cloudflare Public DNS returns. Differences between the two reveal propagation delays, caching issues, or misconfigurations.

Understanding Match Status Results
Each record type gets a comparison status based on whether the authoritative and public DNS records agree. Here's what each status means:
Both servers return identical records (after sorting). Your DNS is fully propagated and consistent. This is the expected state for a healthy domain.
Both servers have records of this type but they differ. Usually indicates a recent DNS change that hasn't fully propagated to public resolvers yet.
Hosting.com DNS has records but Cloudflare doesn't. The domain may not be delegated to Hosting.com, or the records haven't propagated yet.
Cloudflare has records but Hosting.com DNS doesn't. The domain may have migrated away from Hosting.com, or it was never hosted there.
