Random IP Address Generator - Generate IPv4 & IPv6 Addresses

Generate random IP addresses instantly for testing, development, and network simulations. Our generator creates valid IPv4 and IPv6 addresses for mock data, software testing, and educational purposes. All addresses are randomly generated and not associated with real systems.

What Is an IP Address?

An IP (Internet Protocol) address is a numerical label assigned to each device connected to a computer network. IP addresses serve two main functions: network interface identification and location addressing.

IPv4 Example: 192.168.1.100 IPv6 Example: 2001:0db8:85a3:0000:0000:8a2e:0370:7334

How to Use

1. Select IP version - Choose IPv4 or IPv6
2. Set quantity - Generate one or multiple addresses
3. Click "Generate" - Create random IPs
4. Copy results - Use in your projects
5. Generate more - Create additional addresses as needed

Key Features

• IPv4 and IPv6 - Support for both protocols
• Bulk generation - Create multiple addresses at once
• Multiple formats - Standard, compressed, and expanded
• One-click copy - Easy clipboard access
• Valid structure - Properly formatted addresses
• Completely random - True randomization

Understanding IP Address Formats

IPv4 Addresses

Four 8-bit octets (0-255) separated by periods:

format: X.X.X.X
range: 0.0.0.0 to 255.255.255.255
total: ~4.3 billion addresses

IPv6 Addresses

Eight 16-bit groups in hexadecimal, separated by colons:

format: XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX
total: 340 undecillion addresses

Special IP Address Ranges

IPv4 Reserved Ranges

IPv6 Reserved Ranges

Frequently Asked Questions

Are these real IP addresses?

The addresses are randomly generated with valid structure but are not assigned to specific real-world devices. However, any valid IP could theoretically exist on the internet.

Can I use these for production systems?

No. Use these for testing and development only. For production, use properly allocated addresses from your network administrator or ISP.

Will these IPs connect to anything?

Random IPs may coincidentally match real servers, but there's no intentional connection. Don't use them to attempt connections to unknown systems.

How do I avoid reserved ranges?

You can manually filter out reserved ranges, or some generators offer options to exclude private/reserved addresses.

What's the difference between IPv4 and IPv6?

IPv4 uses 32-bit addresses (4 billion possible), while IPv6 uses 128-bit addresses (essentially unlimited). IPv6 was created because we're running out of IPv4 addresses.

Can I generate in a specific range?

This basic generator creates fully random addresses. For subnet-specific generation, you'd need CIDR-aware tools or custom scripts.
