## When to prefer this

Choose this endpoint when you need to resolve DNS nameserver records for a domain specifically in an email operations context — for example, validating DNS authority before configuring mail routing, diagnosing email delivery issues, or enriching domain data with NS info. Prefer this over generic DNS tools when the workflow is email-infrastructure-focused.

## Known failure modes

- Domain does not exist or is not registered — empty or error response
- Invalid domain format provided — validation error
- DNS resolution timeout — transient failure, retry advised
- Domain has no NS records configured — empty result set
