Product Snapshot
loo is a compact DNS lookup utility for Windows built for testing and troubleshooting. It performs queries against DNS servers and displays the raw responses, making it easy to inspect how records are resolved. The interface is intentionally simple so you can run checks quickly and focus on the results.
Core capabilities
- TXT records — fetch text-based entries (useful for SPF, DKIM, and other metadata)
- MX records — determine mail exchanger entries for a domain
- AAAA records — retrieve IPv6 address mappings
- A records — obtain IPv4 address information
In addition to supporting multiple record types, loo provides immediate feedback to help pinpoint misconfigurations or connectivity problems. Its small footprint and free license make it a convenient addition to a network troubleshooting toolkit.
Common scenarios for use
loo is well suited for:
- Verifying DNS setups during deployments
- Diagnosing intermittent resolution or connectivity issues
- Confirming record changes have propagated to specific resolvers
- Quick checks by developers and administrators without opening larger suites
Suggested alternative
Top recommended alternative: iRotate (Free). If you want another free option, iRotate Free is noted as an alternative; review its feature set and compatibility to see if it matches your needs.
