quick answer is no

quick explanation is that cloudflare believes and supports that ipv6 ips should be used instead because ipv4 ip's are ending, so they allow you to use ipv4 only on paid plans

hence the reason they use dummy ip's for your visitors also another reason is that you have this conflict since l2 is not recognizing ipv6

yup that's not private IP, that's public ipv4 but as @Nightw0lf said it seems to be some kind of dummy cloudflare ipv4 address

the client usually sends a trace and 172 starting ips are usually private network ips, maybe i am wrong idk

No, maybe you're getting confused with the 192.* starting IPs, that octet is reserved for LAN as far as I remember ^^

Can I get the ip using httpservletrequest?

or

Servlet

	String externalIp = "127.0.0.1";
	try
	{
		final URL autoIp = new URL("http://ip1.dynupdate.no-ip.com:8245/");
		try (BufferedReader in = new BufferedReader(new InputStreamReader(autoIp.openStream())))
		{
			externalIp = in.readLine();
		}
	}
	catch (IOException e)
	{
	}
	player.sendMessage("Your IP address is " + externalIp);

I tried this. But this outputted the server's ip.

Is it possible to outputted the user's ip?
