randomips

If you are looking for a software that can help you generate random IPv4 addresses, then randomips is worth checking out. With this software, you can generate any number of IPv4 addresses and have them output to your preferred destination - either to stdout or to a specific number of files if you specify the basename.

However, it's worth bearing in mind that the generated IP addresses may not be unique, and the software does not take into account any IANA rules for IP address space. In summary, randomips is a simple and effective solution for generating random IPv4 addresses for your needs, but keep in mind its limitations.
