IPv6 Leak Protection

Stay secure on the web with IPv6 leak protection. Browse the internet from any corner of the globe without worrying about having your IP address exposed. With state-of-the-art encryption algorithms, your digital identity is secured when connected to the VPN.


What is IPv6 Leak Protection?

IPv6 stands for Internet Protocol Version 6 and offers a limitless pool of internet-connected addresses. As most of the internet’s IPv4 addresses are being exhausted, IPv6 has grown in popularity, allowing more users and devices to connect to the internet.

Since most of the population uses IPv4 addresses, IPv6 is largely ignored for those who use it daily. The online threats associated with any IP address are the same, irrespective of their type or protocol. To protect your IPv6 address and secure devices connected to the IPv6 protocol, you might need this feature to secure your privacy.

How IPv6 Works?

IPv6 addresses are 128-bit hexadecimal numbers. The IPv4 address we are all used to seeing are made up of four numerical octets that combine to form a 32-bit address, such as An IPv6 address looks nothing like your familiar IPv4 address; for example, an IPv6 address can be something like 001:0ab3:74a5:0000:0000:71b1:0412:64a3. As you can tell, IPv6 traffic addresses are 128 bits in length and are made up of hexadecimal characters.

In IPv4, each octet consists of a decimal number ranging from 0 to 255. These numbers are typically separated by periods. In IPv6 traffic, IP addresses are expressed as a series of eight 4-character hexadecimal numbers, which represent 16 bits each (for a total of 128 bits). As we’ll see in a minute, IPv6 traffic addresses can sometimes be abbreviated in a way that allows them to be expressed with fewer characters.

How Secure is IPv6?

IPv6 can run end-to-end encryption. IPv6 can run end-to-end encryption.While this technology was retrofitted into IPv4, it remains an optional extra that isn’t universally used. The encryption and integrity-checking used in the current VPN is a standard component to support IPv6 addresses, available for all connections and supported by all compatible devices and systems. Widespread adoption of IPv6 will, therefore, make man-in-the-middle attacks significantly more difficult.

IPv6 address also supports a more -secure name resolution. The Secure Neighbor Discovery (SEND) protocol is capable of enabling cryptographic confirmation that a host is who it claims to be at connection time. This renders Address Resolution Protocol (ARP) poisoning and other naming-based attacks more difficult. And while not a replacement for application- or service-layer verification, it still offers an improved level of trust in connections. With an IPv4 address, it’s fairly easy for an attacker to redirect traffic between two legitimate hosts and manipulate the conversation or at least observe it. IPv6 addresses make it difficult to confirm if your IP address is leaking when you take an IPv6 leak test.

IPv6 Leak Protection with VPN and how does it work?

To ensure complete online anonymity, PureVPN offers IPv6 leak protection. The feature safeguards your online traffic from the eyes of your hackers, trackers, and any other spying entity. Most VPN providers, just like the majority of websites, suffer to support IPv6 leak issues that expose the actual online identity of the person using the VPN service to anyone which you can determine by taking a leak test.

With information and conversations traveling back and forth, having an IP Leakage defense is particularly important. Better than sorry, always make sure after connecting your VPN that your IPv4 and IPv6 are not being leaked by your VPN. Make sure of this by taking the IPv6 Leak Test.
