What is DNS?

The way DNS(Domain Name System) works is by translating domain names to IP addresses so that browsers can interact with each other. Each and every device connected to the Internet has a unique IP address that other devices use to communicate. DNS servers eliminate the need for humans to memorize IP addresses such as 192.168.1.1 (in IPv4), or more complex newer alphanumeric IP addresses such as 2300:de00:1298:1::g482:v6b3 (in IPv6).


How can I check if my VPN is working correctly?

Ensuring if your VPN is working correctly can be a challenge on its own as DNS leaks is a surprisingly common issue. While you may try exploring VPN settings on your own and ensure everything's working fine and avoid DNS leaks, it's not that easy for everyone.

Keeping this in mind, PureVPN has devised a DNS Leak Test which highlights if your DNS (Domain Name Server) request is getting exposed on the web. As security flaws become increasingly common, your real IP is at risk of prying eyes, even if you’re using a VPN, and it’s easy to exploit.

Take the DNS leak test


If I already have a VPN then why do I need to check for DNS Protections?

A VPN connection secures your internet connection by routing your internet requests through the VPN tunnel, hence, disguising your real identity and online activities and keeps you safe from DNS leaks. On the other hand, DNS Leaks are when, due to software issues, your ISP is able to track your internet activities, irrespective of whether you're using a VPN or not!

As your DNS requests give away your browsing habits, they can very well be used against you. In an event, if an individual has access to your DNS related requests, besides your ISP or the VPN server, it’s a cause of concern. This means that your online activities are vulnerable, and you’re not secure anymore due to DNS leaks. To check, take leak test to prevent DNS server leaks or use a VPN service that can prevent DNS servers leaks.


What are the causes of DNS Leakage?

There are numerous causes of a DNS leak. The most common are:

1.Improperly configured network

With improper settings, you’re exposing your device to cyberattacks and data breaches. When you connect a device to a relatively new Wi-Fi network, the network’s DHCP settings (a default protocol that defines your devices’ IP address within the network) can automatically assign the DNS servers to take care of your web requests.

The problem with this is that the DNS server or DNS servers may belong to your ISP or one it may be unsecured (not encrypted) that causes DNS Leak. In such an event, when you connect with your VPN, the DNS web requests will go around the encrypted VPN tunnel, causing DNS leaks.

2.Internet Protocol version 6 (IPv6)

The IPv4 protocol is indeed being exhausted, but at the same time, the internet is in an ongoing conversion phase between IPv4 and IPv6. Most of the VPN services don’t provide IP address of IPv6 which is why for those who are on the IPv6 protocol, the VPN provider would fail to provide security.

To guarantee that you receive the utmost online anonymity, PureVPN offers IP address which has IPv6 leak protection that is designed to protect your online traffic from the prying eyes, hackers, trackers, and surveillance entities, by this you can prevent DNS Leak. Once connected with PureVPN, you can rest assured about your online privacy on IPv4 and IPv6 protocols and stop worrying about DNS Leak.

3.Transparent DNS Proxies

ISPs around the world have crafted a procedure of imposing their self-made DNS server to the user in case a user wants to change the settings to use a third-party server. If an ISP notices any changes made to the DNS settings, they will use a transparent proxy.

A transparent DNS proxy is a cloned server that stops and forwards web traffic to the ISPs owns DNS server or DNS servers. Also known as ISP forcing, this is a form of DNS leak which results due to the malpractice of your ISP. A VPN provider DNS server or DNS servers ensures your web traffic passes through securely and prevents DNS Leak.

4.Outdated Software

Always ensure that your software is updated as updates reinforce your devices’ security against malicious actors. DNS leaks are common with outdated software as opposed to up-to-date software. This way you can also prevent DNS Leak. Always make sure to take DNS Leak Test frequently.
