## Working with dns propagation

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.

## Before you start

Check the hostname, record type or IP address carefully. Compare results using the same query and note whether a cached response may be involved.

## 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.
