IP Address Generation: Testing Networking and Geo-Blocking

Updated Jan 12, 20265 min read

IP addresses are the foundation of network communication. Whether you're a backend engineer testing a logging middleware or a security specialist configuring an IP blacklist, the IP Address Generator is a critical part of your developer toolkit.

IPv4 vs. IPv6

The world is slowly transitioning from 32-bit (IPv4) to 128-bit (IPv6) addresses. Our tool supports both formats, allowing you to test your application's dual-stack compatibility. Make sure your database schemas and regex validators can handle both 192.168.1.1 and 2001:0db8:85a3:0000:0000:8a2e:0370:7334.

Specialized Generation Modes:

  • Public IPs: Generates random addresses from the global routing table.
  • Private Ranges: Create IPs for internal network testing (RFC 1918), such as 10.0.0.0/8 or 192.168.0.0/16.
  • Class-Based: Generate specifically within Class A, B, or C ranges to match legacy system requirements.

🛡️ Security Tip

When testing IP-based rate limiting or geo-blocking, it's safer to use generated random IPs rather than real user data. This ensures your tests are compliant with privacy regulations like GDPR while providing a wide enough distribution to trigger your protection logic.

Client-Side Compliance

In line with our privacy-first philosophy, all IP generation happens locally in your browser. No network requests are made to generate these addresses, ensuring your testing data remains private and your workflow remains fast.

Fuel your network testing with the IP Address Generator. Simple, fast, and secure.
