Questions about this tool family
Why do some network tools need a request?
A browser cannot answer every live network question locally. DNS and remote-host checks need current data from a network service.
Can a parser confirm that network data is safe?
No. A parser explains structure. It does not prove origin, intent, authenticity, or safety.
