IP WHOIS
IP WHOIS Lookup - Find IP Owner
Look up registration and ownership information for an IP address from regional internet registries.
How It Works
WHOIS queries regional internet registries (ARIN, RIPE, APNIC, etc.) to retrieve registration data including organization, contact info, and allocation dates.
Understanding Results
Results include the organization that owns the IP block, network range, country, and administrative contacts. This helps identify who is responsible for an IP.
