Interesting.

- It seems like creating few free cloudflare accounts to get different DNS servers.

- A setting to randomize nameservers almost certainly would become a paid feature.

If I recall correctly, you will get a different set of name servers to set your domain to if you're trying to add the zone to Cloudflare and the name server are already set to the ones you'd usually receive. Possibly because they are using the act of switching the name servers to the CF-provided pair as an act that shows you control the domain.

Mac baby discovers you can use Whois info for details on who owns a site. More at ten.

Thanks for your feedback. I posted this because I've seen many people stop their analysis when they find a site is on Cloudflare.

Were you able to solve the challenge at the end?

I thought the non-random nameserver assignment was interesting. Seems like a flaw, actually.

No, you can't. The article even says that Cloudflare provides WHOIS redaction.

But you would know that if you actually read the article.
