A DNS record points to a provider resource that no longer exists or is no longer controlled by the organization.
Brand, login, app, support, docs, campaign, and cookie-scoped subdomains deserve priority.
Often, but some cases require reclaiming the provider resource, updating routing, or confirming business ownership first.
SafeVibe keeps inventory, risk notes, remediation action, and retest evidence for exposed hosts.
