IP Lookup & WHOIS Lookup
Look up domain registration data, DNS records, RDAP data, IP network information and website diagnostics.
Domain & IP Lookup Tools
Check domain registration details, registrar, expiration date, nameservers, DNS records, IP network registration data, ASN, approximate geolocation, reverse DNS and HTTP response details. Built for webmasters, developers and operations teams.
WHOIS
View registrar, creation date, expiration date, domain status, nameservers and raw WHOIS data.
DNS Records
Lookup A, AAAA, MX, NS, TXT, SOA, CAA and CNAME records.
IP Lookup
Check IP ranges, ASN, organization, geolocation, reverse DNS and abuse contacts.
Diagnostics
Check an HTTPS endpoint, its response time, final HTTPS URL and headers. HTTPS redirect hops are followed safely, with SSRF protection.
Results are collected from public WHOIS, RDAP, DNS and IP data sources. To improve speed and reduce upstream requests, some results are cached for a short time. Always verify critical data with the registrar, authoritative DNS servers or the relevant registry.
