How to use it
- 1
Enter a public global IP address.
- 2
Run the IP RDAP lookup.
- 3
Review the allocation range, CIDR, network handle, statuses, and abuse contact.
What the tool can do
- Uses IANA IPv4/IPv6 RDAP bootstrap and the most-specific prefix match.
- Shows registry range, CIDR0, handle, type, and country field.
- Rejects private, loopback, and other non-global IP addresses.
Common use cases
- Identify the registry network range during incident triage.
- Find the network's published abuse contact.
- Review CIDR and allocation handle without a commercial IP API.
How it works inside
The result describes RIR/registry allocation and may not reflect current routing or address leasing.
IP and RDAP bootstrap URLs use bounded safe HTTP fetching.
Questions and answers
Does the tool show a city?
No. RDAP provides network registration data, not a precise device-geolocation database.
Is this an IP reputation checker?
No. Blacklists, abuse history, and threat intelligence are outside this tool's scope.
