Is this a DNS leak in the VPN?

Question

css

Help me figure out if there is a dns leak.

Connected through a VPN service program, it shows the input IP - YYY.YYY.YY.YY, and the output - XXX.XXX.XX.XX.
Do I understand correctly that the entry IP - YYY.YYY.YY.YY - is seen by my provider, and I only exchange traffic with this ip, and the sites I visit already see XXX.XXX.XX.XX, right?

Those. sites do not need to know - the entry ip, and the provider - the exit ip.

But sites like https://www.dnsleaktest.com/ show (according to test results) the correct login IP is YYY.YYY.YY.YY, is this a leak?

UPD
VPN has a different entry and exit point ip address, which is quite reasonable, but the tests fire the entry point ip, so what's the point of separating it then?

Because float is a floating element not affecting the parent. In the corrected version (I set the color green for clarity), after the floating blocks there is
a correcting the situation

Answer 2

Because you added float. Look in Chrome Dev Tools, for example, and there you will probably notice that the element to which you set the float will not have a height (it will be 0). To fix this, you can set an explicit height, which is somehow not ok, or "clear the boundaries". The property clear: both will help you here. I recommend looking for how to create/apply the clearfix class.
.clearfix::after {
disblay: block;
clear: both;
content: '';
}

"VPN provider" is some unknown crap that can do something, or maybe not do anything and it's impossible to check it in any way - it works or just draws numbers (hello, Internet Cracker!)
