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.

Domain Lookup FAQ
Quick answers about registry lookups on CheckProxy.org.
Public registration data from WHOIS/RDAP: whether the name is taken, registrar, dates, nameservers, DNSSEC, and status flags when the registry publishes them.
CheckProxy defaults keywords without a TLD to .com for a fast international check, then suggests sibling TLDs (.net, .org, .io, and more) under the same label.
Yes. Many registrars redact owner contacts under privacy and GDPR rules. Availability and technical fields are still useful for investigation.
No. Domain Lookup inspects registration metadata. Pair it with Check Proxy, DNS Leak, and WebRTC Leak tests when validating anonymity setups.
Yes. Vietnamese .vn names are queried via regional WHOIS relays; most other TLDs use RDAP or registry WHOIS.
