First of all, the links you found, are about people breaking into nato servers. So actually they lend more evidence that this is not NATO, if its that easy to break into nato servers. But anyway.

nothing to do with CDN

False. Like I said, to believe this fake theory, I would have to physically suppress my own knowledge about how the internet works.

Let me do you a favor and summarise some of the evidence for your fake theory.

1. The Whois dot domaintools dot com screenshot from your link https://defenceforumindia.com/threads/ukrainian-web-resorces-hosted-by-nato.67645/

2. The tracert screenshot from your link https://defenceforumindia.com/threads/ukrainian-web-resorces-hosted-by-nato.67645/

3. The other developer tools HTTP info from tweets like this one https://twitter.com/politblogme/status/1562764808750977024/photo/4

Let me explain how your lack of knowledge forced you into this blind spot of non-credibility.

1. The whois "server type" screenshot says "NATO HPWS/2.1". That's a free text field based on server configuration - you might see apache nginx here. It's free text. The server admin can freely enter anything, write over the APACHE default text with anything you want.

2. "hostnamectl set-hostname" is the linux command to freely type anything into that field. I could type "weavils loves Biden dotcom" in there.

3. The "nato CDN" is a cloudflare IP and returns a RayID which is uniquely cloudflare. The reverse hostname is a free text field delivered in the HTTP response to the client - it's not technically derived or used for anything. Same as how you can freely type your user agent instead of using the Chrome version or whatever.

Its all free text fields. You keep sounding dumb by insisting on something which has no technical basis.

This is a bad conspiracy. You should probably remove this one from your head, because if you repeat it to anyone who knows what they're talking about, you're going to sound like a discredited idiot.
