What is a random IP generator?

A random IP generator creates valid IPv4 address strings for tests, mock data, documentation, and network configuration examples. It does not change your real IP address or send traffic through the generated addresses.

Generated public addresses are not guaranteed to be assigned, online, safe, or owned by you. Use them only as test data unless you have verified the address separately.

How to generate random IPv4 addresses

Set Quantity from 1 to 1,000.
Choose a Range.
For Start–End or CIDR, enter the range in Options.
Select Generate.
Copy all results or open Download .txt to name and save them.

Each batch contains unique addresses, with one IPv4 address per line. Select Generate again to replace the batch. Documentation mode contains 768 available addresses, so its batch cannot exceed 768.

IPv4 range modes

Public

Public mode excludes private, loopback, link-local, documentation, multicast, reserved, and other special-purpose IPv4 ranges. A generated address may still be unassigned or offline.

Private

Private mode generates addresses from the three RFC 1918 ranges:

10.0.0.0/8
172.16.0.0/12
192.168.0.0/16

Documentation

Documentation mode uses the RFC 5737 TEST-NET ranges reserved for examples:

192.0.2.0/24
198.51.100.0/24
203.0.113.0/24

These addresses are suitable for specifications, tutorials, screenshots, and mock configurations.

Any

Any mode can return any syntactically valid IPv4 address, including private and special-purpose addresses. Choose a narrower mode when the address type matters.

Start–End and CIDR

Start–End generates within an inclusive IPv4 interval. CIDR accepts an IPv4 prefix such as 192.168.1.0/24 and includes the full block, including network and broadcast addresses.

The requested quantity cannot exceed the number of unique addresses in the selected range.

Random IP generator FAQ

Can this tool change my IP address?

No. It only creates IPv4 address strings. It is not a VPN, proxy, or IP changer.

Are generated public IP addresses active?

Not necessarily. Public mode filters address types but does not check assignment, ownership, reachability, or device status.

Can the generator create duplicate addresses?

Not within the same generated batch. A later batch may contain an address generated before.

Does CIDR exclude network and broadcast addresses?

No. CIDR mode includes the complete address block.

Can I generate IPv6 addresses?

No. This tool is limited to IPv4 so its ranges and output remain simple and predictable. For IPv6 test data, use the Random IPv6 Generator.
