Official ICANN/RDAP Data, DNS Records & Reverse DNS
Enter a domain name (example.com) or an IP address (192.168.1.1) to get comprehensive information from official registries.
A Whois lookup is a free tool that queries official databases like ICANN to retrieve information about a domain name or IP address, such as the owner, registration date, expiration, and contact details.
This is useful for domain availability checks, investigating potential scams, or verifying website ownership. Our Whois tool at myip.casa provides instant, secure results with added features like reverse DNS lookups.
Whois works by sending a query to registries like ICANN or regional authorities, which return public registration data. Enter a domain (e.g., example.com) or IP, and the tool fetches details in real-time.
It's free and anonymous on myip.casa, no logs kept to protect your privacy. Use it for quick domain and IP searches, or combine it with our other tools like the DNS Leak Test or SSL Certificate Decoder for a fuller picture.
Whois provides details like registrant name, organization, email, address, registration/expiration dates, name servers, and status (e.g., active or suspended).
For IPs, it includes reverse DNS records via RDAP, the current standard used by regional internet registries.
Reverse DNS (rDNS) maps an IP address back to its domain name, useful for verifying email servers or detecting spam.
