Random IP Address Generator
Create IPv4 & IPv6 Addresses for Testing, Development, and Research
Generate random, valid IPv4 and IPv6 addresses in seconds with the Random IP Address Generator. Ideal for developers, network engineers, penetration testers, privacy advocates, and students, this tool offers instant creation of single or bulk IP addresses for any technical scenario—making network configuration, software validation, and cybersecurity assessment faster and safer than ever.
What is a Random IP Address Generator?
A Random IP Address Generator is a specialized online tool that instantly creates valid IP addresses for testing, simulations, and configuration. You can specify ranges, select IPv4 or IPv6 formats, include public or private address blocks, exclude localhost, and export your results for integration into scripts, apps, or test environments.

No sign-up, no limitations, and all operations are privacy-centric.
How It Works
Pick IP Version
Choose IPv4, IPv6, or both, depending on your needs.
Set Address Range
Specify start and end IP addresses for custom subnet or range generation.
Configure Options
Select public, private, or mixed ranges. Exclude reserved and localhost addresses.
Generate
Click for instant results. Export as text, copy, or integrate with code instantly.
Generated IPs comply with formal standards (RFC 791, RFC 4291), supporting subnet notation for advanced network simulation.
Advanced Features
IPv4 and IPv6 Support
Generate classic IPv4 and full IPv6 addresses, ideal for legacy and modern network projects.
Public/Private Range Control
Select public, private (RFC 1918), or custom subnets for precise testing.
Bulk Generation
Instantly create multiple IP addresses for batch configuration and testing.
Subnet and CIDR Output
Includes subnet masks and CIDR notation if needed.
Easy Copy/Export
One-click copying or CSV file download for frictionless workflow.
Privacy by Design
No data or results are tracked or logged.
Why Use a Random IP Address Generator?
Network Testing
Populate routers, firewalls, or switches with random IPs for diagnostic accuracy.
QA & Software Development
Add unpredictable addresses for simulated user data, logs, and error handling.
Security Research
Simulate attacks, penetration tests, or access controls using realistic random IP addresses.
Education
Teach subnetting, addressing, or network topology with valid randomized IP input.
Typical Use Cases
Development & Staging
Assign random IPs to virtual machines, containers, or database tables for simulation.
Security & Penetration Testing
Test firewall rules and access controls by simulating traffic from unpredictable addresses.
Network Education
Explain addressing, subnetting, and routing using accurate, never-repeated random IPs.
Data Masking
Anonymize logs or user data for analytics or compliance testing by converting real IPs into random values.
Developer Tips – Create Random IPs in Code
Python Example
import random
def random_ipv4():
return ".".join(str(random.randint(0, 255)) for _ in range(4))
def random_ipv6():
return ":".join("{:04x}".format(random.randint(0, 65535)) for _ in range(8))
print(random_ipv4()) # Example: 152.72.211.16
print(random_ipv6()) # Example: 2001:0db8:85a3:0832:1234:8a2e:0370:7334JavaScript Example
function randomIPv4() {
return Array.from({length: 4}, () =>
Math.floor(Math.random() * 256)
).join(".");
}
console.log(randomIPv4()); // Example outputUse these routines to automate IP creation in your projects.
Security & Privacy
Randomization is performed client-side for full privacy. No addresses are logged, shared, or reused. When using bulk IPs, always ensure you avoid active, sensitive, or production addresses for compliance.
