Domain Lookup — see who owns the name behind your traffic
Query public WHOIS and RDAP records to verify registration status before you route, spoof, or investigate a host.
CheckProxy Domain Lookup helps privacy operators and researchers inspect domain availability, registrar, creation and expiry dates, nameservers, and DNSSEC — including .com defaults for bare keywords and popular alternate TLDs.
- 01Enter a keyword or full hostname
- 02We query RDAP / WHOIS registries
- 03Compare sibling TLDs for the same label
Bare keywords default to .com. Full hostnames and URLs are normalized automatically.
