2026 Quick-Reference Cheat Sheet & Benchmark Table: RDAP IP, CIDR & ASN Prefix Routing Inspector

Quick Answer & 2026 Technical Summary (rdap lookup tool bgp prefix asn lookup)Updated 2026 Standard

RDAP (Registration Data Access Protocol) is an RFC 7480-standardized successor to legacy port 43 WHOIS. It runs over HTTPS and returns standardized, structured JSON data, supporting internationalization, role-based access control, and seamless RESTful querying. Use this interactive rdap lookup tool bgp prefix asn lookup above to test modern whois rdap tool, asn bgp prefix lookup, and ip network allocation inspector locally in your browser with zero server uploads.

Step-by-Step Workflow

4 Easy Steps
01Phase 1

Enter IP Address or ASN

Type any IPv4 (e.g. 1.1.1.1, 8.8.8.8), IPv6, or ASN (e.g. AS13335, AS15169) into the input box.

02Phase 2

Click Inspect RDAP

The tool automatically detects the IP/ASN format and targets the appropriate authoritative RIR endpoint.

03Phase 3

Review Network Hierarchy

Inspect NetRange, CIDR notation, ASN designation, Country code, and Organization details.

04Phase 4

Export JSON or Summary

Copy the formatted summary report or raw structured JSON for your incident ticket documentation.

Real-World Applications

Threat Intelligence & SOC Triage

Identify hosting providers, cloud infrastructures, and network abuse desks for suspicious IPs during security alerts.

OSINT Infrastructure Mapping

Map out enterprise ASN IP ranges and associated CIDR blocks during passive external penetration test recon.

Modern WHOIS Replacement

Bypass legacy port 43 WHOIS firewalls and query structured, standardized JSON registration records over HTTPS.
