About Random IP Address Generator

The Random IP Address Generator creates random IPv4 or IPv6 addresses for testing, network simulations, dummy data generation, security research, and load testing scripts. Generate up to 100 addresses at once with a single click.

Developers and QA engineers frequently need IP addresses in test data, but using real IPs from production environments raises privacy and compliance concerns. Generated addresses follow the correct format and fall within defined ranges without being associated with any real device, user, or location.

Choose from three address classes: public (globally routable addresses that look realistic in test data), private (RFC 1918 ranges — 10.x.x.x, 172.16–31.x.x, 192.168.x.x — for simulating internal network scenarios), or any (unrestricted random generation). For IPv6, output comes in full expanded notation or compressed notation with :: for consecutive zero groups.

Common uses include populating test databases with dummy IP address fields, generating mock server logs, testing firewall rule matching, creating network simulation scripts, and generating placeholder values for API response mocks and fixtures.

All addresses are randomly generated and carry no association with any real device, network, ISP, or physical location. Everything runs locally in your browser and no sign-up is required.

How to Use Random IP Address Generator

  1. Choose IPv4 or IPv6.

  2. Select the address type: public, private, or any.

  3. Set the count (up to 100).

  4. Click Generate and copy the results.

Frequently Asked Questions

Are these real IP addresses?

No — they are randomly generated values that follow the correct format but are not tied to any real device, ISP, network, or physical location. They are safe to use as placeholder data in databases, test fixtures, and API mocks.

What are private IP address ranges?

RFC 1918 defines three reserved private ranges that are not routable on the public internet: 10.0.0.0–10.255.255.255 (Class A), 172.16.0.0–172.31.255.255 (Class B), and 192.168.0.0–192.168.255.255 (Class C). These are used for internal networks, home routers, and virtual machine networking.

Can I generate IPv6 addresses?

Yes — select IPv6 mode to generate full 128-bit addresses in hexadecimal colon notation (e.g. 2001:0db8:85a3:0000:0000:8a2e:0370:7334), optionally compressed with :: notation for consecutive zero groups.

Can I use generated IPs in test data?

Yes — the generated addresses are correctly formatted for use as sample data in database seed files, test fixtures, API response mocks, log parsers, and network simulation scripts.

What is the difference between public and private IP addresses?

Public IP addresses are globally routable on the internet and assigned by ISPs. Private IP addresses (RFC 1918 ranges) are used within internal networks and require NAT to access the internet. Use public IPs to simulate internet traffic in tests, private IPs to simulate internal network scenarios.

Can I generate IPs in a specific subnet or CIDR range?

The generator currently produces addresses within the standard public, private, or any range. For IPs within a specific CIDR block (e.g. 192.168.10.0/24), generate private IPs and filter results to the desired subnet, or use a dedicated network testing tool.
