A security engineer suspects that a name server is leaking internal host details that do not typically appear in casual lookups. Which method best verifies that a name server is exposing details that are not visible to straightforward queries?
Perform reverse lookups on each suspected record
Compare historical domain snapshots for hidden data
Scan the site with a domain crawler to list all paths
Initiate a direct zone copy from the suspect name server
Requesting a direct zone copy from the name server can confirm that the domain has been misconfigured to share sensitive records beyond normal lookups. Reverse lookups and historical snapshots rely on existing public-facing data rather than extracting complete record sets, and a domain crawler targets publicly linked paths without uncovering configurations concealed within a name server.
