About Random IP Generator
This tool generates random IP addresses within specified CIDR ranges, perfect for network testing, simulation, and configuration validation. All generation is performed locally in your browser.
Common Use Cases:
- • Network Testing: Generate test IP addresses for network configuration
- • Load Testing: Create diverse IP addresses for load balancer testing
- • Firewall Rules: Test firewall rules with various IP addresses
- • Network Simulation: Simulate network traffic from multiple sources
- • Documentation: Generate example IP addresses for documentation
Special Address Exclusions:
- • IPv4 .0: Network address (first address in range)
- • IPv4 .1: Common default gateway address
- • IPv4 .255: Broadcast address (last address in range)
- • IPv6 ::: Network address (all zeros in host portion)
- • IPv6 ::1: Loopback address in host portion
- • IPv6 ::ffff: IPv4-mapped reserved address
CIDR Notation:
CIDR (Classless Inter-Domain Routing) notation specifies the network prefix length. For example, /24 in IPv4 means the first 24 bits are the network portion, leaving 8 bits for host addresses (256 total addresses). In IPv6, /64 is commonly used, providing 2^64 addresses in the subnet.
