A high-performance IP geolocation lookup engine (QZDB) with multi-language SDKs (Rust, C/C++, Go, Java, C#, Node.js, Python, PHP) that resolve IPv4/IPv6 addresses to location, ASN, and risk metadata using a Patricia Trie and mmap zero-copy design. It also ships phone-number location SDKs, database import scripts, and sample data, with the underlying IP database updated monthly.

Use cases

• look up the country and city for an IP address
• resolve IPv6 addresses to geolocation offline
• get ASN and usage type for IP risk scoring
• find the carrier/ISP of an IP in Go or Rust
• import IP ranges into MySQL or PostgreSQL
• look up mobile phone number location in China
• build anti-fraud and anti-crawler IP checks

When to choose

• you need microsecond-level, high-throughput offline IP geolocation lookups
• you need both IPv4 and IPv6 support in one database
• you want SDKs across many languages with zero-allocation query paths
• you need ASN, carrier, and risk-oriented fields for traffic control

When to avoid

• you need a free open-data IP database - the data itself is a commercial monthly-updated product
• you need real-time online IP intelligence APIs rather than local binary lookups
• your language is not among the eight supported SDKs
• you require an OSI license - the repo has no explicit license file
