Random IP Address Generator

This network utility generates syntactically valid IPv4 and IPv6 addresses using cryptographically random number generation within defined address space boundaries. IPv4 generation follows the classful addressing scheme: Class A (1.0.0.0–126.255.255.255), Class B (128.0.0.0–191.255.255.255), and Class C (192.0.0.0–223.255.255.255), excluding reserved ranges like 127.x.x.x (loopback) and 0.x.x.x (network addresses).

The scope filter distinguishes between public (routable) and private (RFC 1918) address spaces. Private ranges include 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16, which are reserved for internal networks and cannot appear on the public internet. IPv6 generation produces full 128-bit addresses formatted as eight groups of four hexadecimal characters separated by colons, providing addresses from a pool of approximately 3.4×10^38 possible combinations.

Each generated address displays supplementary metadata including the IP class designation, corresponding subnet mask (255.0.0.0 for Class A, 255.255.0.0 for Class B, 255.255.255.0 for Class C), and public/private scope classification. Batch generation produces up to 50 addresses simultaneously, with individual and bulk copy functionality for rapid integration into network testing configurations, firewall rule testing, and development environment setup.
