If you have heard the term IPv4 and/or IPv6, you may have wondered what the difference is or which is the most secure to use. Luckily, we can help you answer both of those questions. We’ll tell you why it is important and the differences between the two. Before we do, though, we ask that you please take a look at our list.

IPv4 stands for internet protocol version 4. That shows up as the standard IP address quartet. In other words, the standard web address that is similar to 127.0.0.1 and more. It may be familiar to you because it has been around since 1983. The big problem with the IPv4 series of numbers is that with so many websites and smart devices these days, we have run out of numbers.
Unlike IPv4, IPv6 multiplies the available numbers. Unlike the 4.3 billion numbers offered by the 32-bit addresses, the new one offers 128-bit IP addresses. As you can guess, the numbers are exponentially larger. instead of 4.3 billion, the new address protocol supports rough 3.4×10 to the 38th power.
All of this said, IPv6 does encounter one big issue, it is expensive. The truth is you will need newer equipment that will be able to handle the new addresses and transfer the traffic correctly. That is why only 7 countries have more than 15% converted addresses.
Should I Use IPv6?
Yes you should whenever possible. The benefits are added security and privacy because of all of the different and unique numbers available. However, that also means that IPv6 is vulnerable to being highjacked and may leak. Until everyone upgrades to IPv6, you may be better off using the IPv4 protocol. Many VPNs do not support it and of the ones that do, most leak. In fact, most providers just have you disable the IPv6 protocol instead of fixing any leaking issues. Please share this post with your friends so they can decide if they also want to switch to the IPv6 protocol. Follow us @VPNFan for the latest deals and guides.
