Generate IPv4 and IPv6 addresses on demand. Supports specific public/private networks and custom CIDR ranges. Ideal for testing, development, and learning.
IPv4: 32-bit address, e.g. 192.168.1.1
IPv6: 128-bit address, e.g. 2001:0db8:85a3::8a2e:0370:7334
Locally stored history of your last 20 generated IP addresses.

RIPEMD Hash Generator
Generate RIPEMD-128, RIPEMD-160, RIPEMD-256, and RIPEMD-320 hashes online. Supports text, Hex, and Base64 inputs.
IPv6 Address Compressor
Compress IPv6 addresses to their shortest RFC-compliant format by removing redundant zeros. Perfect for network configuration and address management.
IPv4 / IPv6 Address Converter
A two-way IPv4 and IPv6 address converter for network configuration, debugging, and format validation.
When you need a large number of IP addresses for software testing, network configuration simulations, or security experiments, manually making them up is time-consuming and prone to errors. The core function of this tool is to generate random addresses that comply with Internet Protocol (IP) formatting standards. An IP address is the unique logical identifier for network devices in a TCP/IP network, divided into two main versions: IPv4 (e.g., 192.168.1.1) and IPv6 (e.g., 2001:0db8::1). Based on your selections (address version, type, and CIDR range), this tool algorithmically generates a specified number of valid IP addresses and outputs the results in a clean list format.
Q: Can the generated private IP addresses access the internet directly?
No. Private IP addresses (such as 192.168.x.x or 10.x.x.x) are only valid within local area networks (LANs) and cannot be routed directly to the public internet, as dictated by the TCP/IP protocol. The private IPs generated by this tool are primarily for internal network testing and simulations.
Q: How do I generate random IPs within a specific subnet?
Using CIDR notation is the most convenient method. For example, if you enter "172.16.0.0/12", the tool will only generate random addresses within that subnet (i.e., from 172.16.0.0 to 172.31.255.255). This is the most efficient way to limit the IP generation range.
Please ensure that the CIDR or start/end address formats are correct (e.g., four decimal blocks for IPv4). We recommend setting a reasonable generation count based on your actual needs; generating too many at once (e.g., over 10,000) may affect browser responsiveness. Please note that all IP addresses generated by this tool are simulated data and are strictly prohibited from being used for cyberattacks, fraud, or any other illegal activities. There is no guarantee that the generated addresses are not currently in use in the real world, so do not configure them in production environments.
For network engineers and developers, properly utilizing a random IP generator can significantly improve testing efficiency. A typical use case is generating test data: for instance, to validate firewall rules, you can generate a set of random private addresses within the "10.2.0.0/16" subnet, along with a set of public addresses, to simulate internal and external network traffic. The key is understanding CIDR: a smaller subnet mask (e.g., /8) represents a larger subnet and a broader range of generated addresses, while a larger mask (e.g., /30) represents a smaller subnet with limited address options. After generating the IPs, we recommend using the "ping" command or network scanning tools in an isolated test environment to verify their logical validity.
