The term “DNS Leak” may seem like gibberish to you, and that’s okay – not a lot of people are going to be familiar with the phrase. When it comes to dealing with DNS leaks, knowing where to start is tough, but that’s what we’re here to talk about today. Now, before we delve deeper, just know that DNS leaks would apply to your ISP (Internet Service Provider) potentially knowing about your browsing activities. Staying anonymous while browsing the internet is critical, especially when it comes to doing so on a very frequent basis. If you’re serious about staying private online, DNS leaks are something that you need to be worried about. When you’re using a VPN from somewhere like BestVPNCanada (http://188.8.131.52/~bestvpncanada), a DNS leak could completely defeat the purpose of putting that security protocol in place. That’s why we’re here to fix things for good!
DNS is an abbreviation for Domain Name System, which is a system that links URL’s (which is the actual address you type in for a website, like ‘www.example.com’) to the IP’s in which the websites will be associated with. Whenever you visit a website, a process takes place in which a request gets sent over to a DNS server. This request has the URL that you just typed in and asks for the proper IP needed for connection, leading you to the web page itself (that’s a necessary process when it comes to keeping the internet intact!).
Why Do DNS Leaks Happen (and Why Are They Worrisome)?
DNS servers are essentially always assigned by your respective ISP’s, and that means that they’ll have an opportunity to take a look at which websites you’re frequenting. If you make a request to the server and ask for a connection, they’ll probably see it – that’s why when you’re using a VPN, the request itself needs to be directed towards an anonymous DNS server. This cuts your ISP out of the monitoring equation as a whole, and will allow you to browse without accidentally tipping them off. Now, there are going to be instances of browsers acting up and just completely ignoring the fact that there’s a VPN running. When this happens, the DNS request can be sent to the regular ISP’s DNS servers. This is what we call a “DNS Leak”, and it has the potential to let your ISP’s in on any browsing secrets you may have.
When you have a VPN active, you automatically think you’re accounted for in the privacy department; but now we know that isn’t the case. Some VPN services will offer up a feature that checks your DNS request on a frequent basis, ensuring that they’re always being sent through the private DNS server (as opposed to the one that your DNS is capable of monitoring).
Some of the best VPN’s around are going to implement DNS Leak Protection, so it’s crucial that you do some research and find the proper fit. BestCanadaVPN is a perfect fit for most people, especially those that live in Canada!
