Random IP Generator

The Random IP Generator lets you instantly generate one or more random IP addresses within a defined range.

You can set the start and end points for the range, exclude private, loopback, multicast, broadcast, or reserved IPs, and control the order of generation. It is also possible to control whether the generated IPs are unique or not.

It’s useful for tasks like network testing or simulations such as a mock network log.

An IP address is a unique number that identifies a device on a network, like the internet. It works like a home address, letting data know where to go.

IPv4 addresses are made up of four numbers, called octets, each between 0 and 255, separated by periods (.), like 192.168.0.1.

Every device connected to the internet has an IP address so it can send and receive information.

An IP range is a set of IP addresses that start at one address and end at another. It defines all the possible IP addresses between these two points.

For example, the range from 192.168.0.0 to 192.168.0.255 includes every address between those two points.

IP ranges are often used to manage networks or assign IPs to devices.

To calculate the number of possible IP addresses in a range, you need to know the start and end points of the range.

Subtract the start point from the end point, and add 1 to the result.

For example, if the start point is 192.168.0.0 and the end point is 192.168.0.255, the calculation would be (255 - 0 + 1) = 256 possible IP addresses.

For broader ranges spanning multiple octets, you'll need to treat each octet separately. For example, if the range is from 192.168.0.0 to 192.168.255.255, the calculation would be (255 - 0 + 1) * (255 - 0 + 1) = 65,536 possible IP addresses.

When using this tool, you can exclude certain IP ranges to avoid generating IPs that are reserved for special purposes.

For example, you might want to exclude private IPs to ensure that the generated IPs are routable on the public internet. You might also want to exclude multicast or broadcast IPs if you are only interested in unicast IPs. Or you might want to exclude loopback IPs if you are generating IPs for a network simulation, as loopback IPs are not routable on a real network.

This Random IP Generator can be useful for many purposes, for instance:

• Network Testing: When setting up a test network, you may need a list of random IP addresses within a certain range to simulate traffic or test configurations.
• Security Audits: Cybersecurity teams can use random IPs to test firewall rules, intrusion detection systems, or other security measures to ensure that unwanted IPs are properly blocked or allowed.
• IP Allocation: If you're working with a large pool of IPs and need to assign them to devices or servers, this tool helps you randomly generate addresses to avoid manual selection.
• Load Balancing: For network load balancing tests, random IP generation can help distribute network requests evenly across a set of servers or endpoints.
• Simulations: Researchers or engineers working on simulations of internet traffic or behavior can use random IPs to simulate realistic network environments.
• Developing IP-Dependent Software: If you're developing software that interacts with network devices, having a range of random IP addresses helps to ensure that your software handles different IPs correctly.
