Generates IPs randomly strictly within this subnet.

About IP Address Generator

A flexible tool for developers and network engineers to generate bulk IPv4 and IPv6 addresses. Perfect for testing firewall rules, populating database mocks, or simulating network traffic logs.

IPv4 & IPv6

Full support for the classic dot-decimal notation (IPv4) and modern hexadecimal format (IPv6).

CIDR Subnets

Need IPs from a specific LAN? Enter a CIDR block (like 192.168.1.0/24) to generate valid host IPs within that range.

Frequently Asked Questions

1. What is CIDR?

Classless Inter-Domain Routing (CIDR) is a method for allocating IP addresses and IP routing. It uses a suffix (e.g., /24) to denote how many bits represent the network prefix.

2. Are these IPs active?

No, they are randomly generated numbers. Some might coincide with real servers, but most will be unassigned or private.

Cheat Sheet
  • IPv4: 32-bit address, e.g., 192.0.2.1

  • Private Ranges:
    • 10.0.0.0/8
    • 172.16.0.0/12
    • 192.168.0.0/16
