Look up IPv4/IPv6 network ownership, ASN, and approximate geolocation with disclosed external sources and privacy boundaries
Query A, AAAA, CNAME, MX, NS, TXT, SOA, and other DNS records with organized TTL and record values
Locally parse browser, rendering engine, operating system, and device details from User-Agent strings with identification caveats
Calculate IPv4/IPv6 ranges, masks, address counts, and subnet containment
