Feature List & Architecture

Networking & OSINT

The NewhouseNet WHOIS & ASN Intelligence Engine combines RFC 3912 TCP socket communication with BGP routing lookup to provide instant domain lifecycle and network topology intelligence.

📡 RFC 3912 Socket Protocol Queries raw port 43 WHOIS servers directly over TCP sockets, following IANA and registrar referrals without relying on third-party commercial APIs.

⏳ Domain Expiration Tracking Parses registry expiration timestamps into exact countdowns to identify impending domain renewals and prevent accidental domain lapses.

🌐 Autonomous System (ASN) Routing Extracts BGP origin prefixes, Autonomous System Numbers (ASN), organization ownership, and RIR regional registries (ARIN, RIPE, APNIC).

🛡️ Reverse DNS (PTR) Resolution Automatically resolves in-addr.arpa PTR pointer records and validates RFC 1918 private vs. globally routable public addresses.
