Are the generated IPs real, in-use addresses?

They are random and valid in format, but not checked against anything. A public-range address may belong to a real host, so use them as sample data and never for scanning or testing systems you don't own.

Which ranges count as private?

For IPv4: 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. For IPv6, unique local addresses in fd00::/8. Public IPv4 excludes private, loopback, link-local, multicast, and documentation ranges.

Are the addresses cryptographically random?

They are drawn from the browser's crypto.getRandomValues, so they are unbiased, but they are meant for test data, not secrets.

Is anything uploaded?

No. Generation happens entirely in your browser.
