WHOIS and RDAP lookup
Look up domain and IP registration records to identify allocation and administration. Registration country is not a user location, and complete records are not reputation evidence.
Using and interpreting this tool
Confirm the target and measurement point, then start the checks you need. Results retain sources, observation times and missing-data reasons. Traffic-intensive checks require a separate start.
After changing one setting, start a fresh run and compare A/B snapshots in history. Unknown, unconfigured and inapplicable do not mean passed.
