Free Whois Lookup
yWhois provides a free service to check registration details for domain names, ASNs, or IP addresses using RDAP (Registration Data Access Protocol).
Your IP address is 216.73.216.208
yWhois should automatically detect whether you're looking up a domain name, ASN, or IP address. If this doesn't seem to be working correctly, refer to the formatting tips.
Formatting Tips
Domains
Enter only the main domain (e.g., example.com). Do not use www. Subdomains are not supported. Supported TLDs include most common extensions. Check the full list here.
ASNs
Input the ASN with the 'AS' prefix followed by the number (e.g., AS133335). Do not include spaces or additional characters.
IP Addresses
Enter a single IPv4 (e.g., 1.1.1.1) or IPv6 (e.g., 2001:db8::1) address. Do not use CIDR notation (e.g., /24) or ranges.

How does yWhois work?
When you submit a lookup, the web server randomly selects a worker server to process your request. The worker uses a custom API to query the appropriate RDAP server for the domain, ASN, or IP address you entered. The RDAP response is sent back to the web server. Then we uses JavaScript to attempt to format the results. If the formatting isn't perfect, you can view the raw RDAP data at the bottom of the results page.
