    While I kept settings as

    Is there way to block this leakage?

    I'm a little confused. Your screen shot shows that it is NOT leaking WebRTC.
    As for DNS leaks, I don't think that's controlled by the browser.

    By the way, your attempts at security are actually making it relatively easy to track you, regardless of how great a VPN you may use.

    Sites are regularly informed of information like which device and OS version you're using (a relatively small number of people are using the same device), you have DNT enabled (an even smaller number of users), cookies are disabled (a very small number). That all combines to make your browser fairly unique. And that's just the easy stuff.

    WebRTC & DNS request Leaking in BlackBerry Browser!-img_20170517_153122_edit.png

    When I check same website in my PC with Chrome Browser with 'WebRTC prevent' extension, then I seen 0 Server. So my PC's browser is not leaking WebRTC or DNS request.
    1. If I manage to prevent on PC, can it possible in BlackBerry Browser?
    2. As per my browser settings WebRTC off, then also it leaking it, means might be that setting not working properly?

    I think the DNS leaks are an issue with the VPN rather than the browser.

    While I appreciate that the message about WebRTC is rather vague and inconsistent, if you actually had a WebRTC leak it would be showing the actual leaked information. Since it's not showing any actual information, I don't think there is a leak.
    You can try flipping the switch in the settings and then reloading the page to see what it looks like when there is a leak.

    Again, WebRTC has nothing to do with DNS. WebRTC can be disabled, DNS cannot. Well, at least, if you still want to be able to surf the internet that is. You might choose a different DNS resolver though and read up on DNSSEC and DNSCrypt if you want more security. You might as well check on these sites too https://dnsleaktest.com/ https://browserleaks.com/ip .

    A good VPN will make the DNS leaks just point to the VPN provider instead of you.
    And if you're not using a VPN, then I don't see a point in worrying about DNS leaks since you're already sharing your IP anyways.

    Sure, that's alright. But one could worry about manipulating DNS requests.
