Understanding The Concept Of A DNS

Whether you are trying to protect your small business or a large corporation, you need to understand the meaning of a DNS. A DNS is basically just a protocol that is essential to access certain websites. Without this DNS address, you would not be to access any of your favorite websites or even check your e-mail. While IP addresses consist of numbers that range anywhere from .0 to .255, most individuals don’t even remember their DNS addresses. In fact, if you are like most individuals you probably don’t even remember your phone number.

DNS stands for Domain Name Server and it is basically an essential library of aliases that help translate the different domains that you have visited. Whenever you visit a certain website or type a domain name into the address bar or a website, you are consulting a domain name server before accessing that website. While the process usually happens behind the scenes, you don’t have to even worry about knowing the DNS address or server. Unfortunately, just the slightest leak could cause the most difficult and complex problems in the simplest of networks.

What Happens When There Is A DNS Leak?

DNS leaks not only leave a gaping hole in your security, but they could potentially expose your browsing and personal information as well. This would virtually allow anyone to track your online activities. For most individuals, the quickest and fastest way to detect one of these leaks is by visiting a website that offers a DNS test. If you have done your research you will know that there are plenty of websites that offer these tests for free.

Typically Internet Service Providers, such as Comcast and AT&T, provide the DNS servers. While it is uncommon for ISP’s DNS servers to become unavailable, it does happen. In most cases, it is possible to resolve the issue by utilizing Google’s DNS servers, which can be very risky. If you are concerned about your privacy, you should stick with a VPN provider’s DNS service.


 One of the most common causes of privacy loss is a DNS leak, which can be remedied with a few tweaks. The best way to detect these leaks is with a high-quality VPN leak detector. Experts recommend utilizing the detector at least every month.
