Working with whois lookup
A network lookup is a snapshot from a particular resolver, location and time. DNS answers, routing paths and certificates can change, so a result is most useful when the query and observation time are clear.
Common questions
Why do DNS results differ between locations?
Resolvers can cache records for different periods, and some services deliberately return location-specific answers. A mismatch does not on its own identify a configuration fault.
Can browser code perform every network check?
Browsers restrict arbitrary network access. Some diagnostics need a server or a public service; that service’s observation point affects what the result means.
