IP Network Info Analyzer

A multi-address IPv4 and IPv6 network ownership, Regional Internet Registry (RIR) allocation, RDAP entity, and reverse DNS PTR diagnostics tool for Linux.
A lightweight Linux alternative to IPNetInfo for extracting public IP addresses from email Received headers or server logs and inspecting their autonomous systems and registry records.

Key features:
- Extracts public routable IPv4 and IPv6 addresses directly from pasted email Received headers, traceroute outputs, or server diagnostic logs while filtering private RFC 1918 and loopback addresses.
- Queries authoritative RIR RDAP endpoints (ARIN, RIPE NCC, APNIC, LACNIC, AFRINIC), WHOIS ASN records, and reverse DNS PTR hostnames concurrently.
- Parses CIDR prefixes, allocation ranges, NetName, Origin ASN, registrant organization, country code, vCard abuse contacts, and registration dates.
- Visualizes RIR, Country, and Autonomous System (ASN) distribution charts and exports structured CSV and JSON network diagnostic reports.
