Common questions about our domain research toolkit
Yes! All our domain tools are 100% free to use. You can perform unlimited searches for WHOIS lookups, DNS records, SSL certificates, and other domain information without any charges.
WHOIS lookup is a tool that displays domain registration information including owner details, registrar, registration date, expiration date, and nameservers. It helps you find who owns a domain and when it was registered.
Our DNS lookup tool queries authoritative nameservers in real-time, providing accurate and up-to-date DNS records including A, AAAA, MX, TXT, CNAME, and NS records for any domain.
Currently, our tools check one domain at a time for accurate results. For bulk operations, you can use our Bulk Domain Search tool which allows checking availability of multiple domains simultaneously.
We recommend checking your SSL certificate monthly to ensure it hasn't expired and is properly configured. SSL certificates typically expire annually, and monitoring helps prevent security warnings on your website.
