Website & DNS Tools FAQ

Should I only check domains I own?

Use network and website diagnostics only on domains, hosts, APIs, or systems you own or are authorized to inspect.

Why do DNS results vary?

DNS changes, caching, resolvers, TTLs, and geographic routing can produce different answers.

Are results official?

No. Results are informational snapshots from this network path.

What does a snapshot result mean?

It reflects the response at the time of the check and may change later.
