Troubleshooting questions

What does NXDOMAIN mean?

NXDOMAIN is a DNS response stating that a name does not exist. Check spelling, the domain suffix and the exact subdomain. If a record was just created, a recursive resolver may still cache an earlier negative answer, so consider when the change was made.

Does “All types” include every subdomain?

No. It queries common types for the name you enter. Subdomains, service records and email authentication records require their own complete names.

Why can this differ from my DNS control panel?

These answers come from a recursive resolver and can reflect its cache, proxy settings or provider-specific features. Compare TTL and the actual configuration; a single lookup is not a global propagation test.
