Offline IPv4 and IPv6 country, RIR allocation, and RFC scope lookup
Offline IP Country and RIR Lookup is a desktop network address classification, country attribution, and Regional Internet Registry (RIR) delegation lookup utility for Linux. An independent Linux alternative inspired by IPInfoOffline, it resolves IPv4 and IPv6 addresses locally against a bundled IANA and five-RIR CIDR dataset using binary search with sub-0.1 millisecond lookup latency and zero external GeoIP API requests.
Key Features:
- 100% Offline RIR & IANA Dataset: Bundles compiled delegation records from ARIN, RIPE NCC, APNIC, LACNIC, and AFRINIC covering global IPv4 and IPv6 allocations across more than 240 ISO-3166 country and territory codes.
- Full RFC Address Classification: Identifies RFC 1918 private networks, RFC 6598 CGNAT shared space, loopback, link-local, documentation, multicast, and IPv6 ULA ranges.
- Log File IPv4 & IPv6 Extractor: Extracts and counts unique IPv4 and IPv6 endpoints from server logs, configuration files, or pasted text.
- Custom CIDR CSV Overlay & Reports: Imports custom subnet CSV mappings for internal networks, renders RIR and country distribution charts, and exports CSV and JSON files.
Disclaimer: This project is an independent open-source tool and is not affiliated with, sponsored by, or endorsed by NirSoft or the Regional Internet Registries.
