IPv4 vs IPv6 for VPN services and getting access to Netflix

Netflix IPv4 and IPv6If you have been using the internet for a while, it is likely that you have come across the terms IPv4 and IPv6 at some point. They refer to Internet Protocol version 4 and version 6. IP addresses are what allows computers and other devices to access the internet and they are used to identify the senders and receivers of online communications. They are the element that allows websites to keep track of your physical location. The selection of the Internet Protocol has gained importance over the last few years, particularly when it comes to unblocking streaming websites or for instance, getting access to the US version of Netflix. This is why you need to keep this in mind when deciding if you should look for a VPN that supports IPv4 or IPv6.


This is the protocol that is being used currently and it has been used for decades, which means that it is a reliable solution. Every IP address in IPv4 is 32 bits long, so it is easier to remember. IPv4 systems don’t use as much memory than IPv6 and they require less programming, because they transmit 4 bytes, rather than 8 bytes, which could be a large overload of information. At the time IPv4 was originally developed, the future advances in technology and the fact that millions of devices would be connecting to the internet, were not envisioned, which is why, the protocol is running out of numbers as the limitation in the digits means that all possible addresses are being assigned and soon there won’t be more left.


Since IPv4 is running out of number as the amount of internet users is increasing all over the world, an alternative had to be created and this is how IPv6 was born. An IPv6 IP address has 128 bits, meaning that the amount of IP addresses that can be assigned is considerably higher. This means that IPv6 has larger capacity and it is safer than IPv4, as it provides an authentication option, making the packets sent over the internet more secure. However, it has a disadvantage and that is that sometimes it is vulnerable to DNS leaks. This is why many VPN providers have opted for IPv4 instead. Plus, IPv6 is not supported by all networks yet.

How to access Netflix

Although Netflix is available pretty much everywhere since the streaming service’s global expansion took place back in 2016, the best catalog of movies and TV shows is still available in the United States. Subscribers in other countries usually have limited options, compared to what those in the US enjoy. This is why many people look for ways to get around the blocks to access the US version of Netflix. Since Netflix offers the content based on licensing agreements, it has to ensure that people can only watch the movies and TV shows that are licensed for their location. To prevent users from accessing content outside their geographical locations, Netflix has implemented blocks that don’t allow people to bypass the region-based restrictions. Currently, only a few VPNs are able to get around these blocks since Netflix’s system is very effective when it comes to detecting the attempts to get around the restrictions.
