IP WHOIS Lookup: Your Digital Detective for Internet Intelligence
Ever wondered who's behind that mysterious IP address? Is it a legitimate business from Paris... or something more suspicious from who-knows-where?
With our IP WHOIS Lookup tool, you'll uncover the ownership details behind any IP address. It's the WHOIS detective you didn't know you needed — but will definitely rely on. Paste an IP and reveal its registration secrets instantly.
It's comprehensive. It's reliable. It works. Let's go.
What Is WHOIS Information?
WHOIS data is like the property records of the internet. It tells you who owns and manages IP addresses, including registration dates, network ranges, and contact details for the organizations responsible.
Two kinds of IP addresses can be looked up:
- IPv4 – the classic format (looks like 123.45.67.89)
- IPv6 – the newer, longer format (looks like 2001:0db8:85a3:0000:0000:8a2e:0370:7334)
Every device has an IP, and every IP is registered to an organization in the WHOIS database.
What Our WHOIS Tool Reveals
Our tool goes beyond basic IP location to show you the full registration details and network ownership information:
- 🏢 Organization name and contact information
- 📋 Network allocation details (CIDR blocks, IP ranges)
- 📅 Registration and allocation dates
- 🌐 Regional Internet Registry (ARIN, RIPE, APNIC, etc.)
- 📞 Technical and administrative contacts
- 🔍 Network infrastructure details
We retrieve raw WHOIS records directly from authoritative sources — giving you the full technical details, not just simplified summaries.
Why Use Our WHOIS Lookup?
- Verify Network Ownership

Is the WHOIS Data Always Complete?
Let's be realistic about WHOIS data limitations:
- Some registrants use privacy services to mask their details
- Different regional registries provide varying levels of detail
- Some historical allocation information may be limited
- WHOIS databases are independently maintained by each registry
Our tool connects to multiple authoritative sources to provide the most complete picture possible.

Understanding WHOIS Privacy
WHOIS data is publicly available by design - it's meant to provide transparency about who operates internet resources. That said, the level of detail varies by registry policies. Some organizations use privacy services for domains but cannot fully shield their details for IP allocations.
