How good IPv6 VPN is? Is IPv6 faster than IPv4? The following post will explain why IPv6 is adopted & the importance of VPN using IPv6.
What is IPv6 and how does IPv6 affect your VPN? If you are not familiar with the concept of internet IP address, then you’d better know that the change from your current IPv4 to IPv6 is a big thing. It could possibly change your internet usage profoundly, especially the IPv6 and VPN. Also, you could have a look at the best VPN for IPv6 in a handful of candidates – The iTop VPN for IPv6, and see if the IPv6 VPN is faster than IPv4 VPN.
To understand what is IPv6, you must know what IP address it is. IPv6/IPv4 is the abbreviation of Internet Protocol version 4/6. The IP address is the initial part of the internet protocol suite, which is also called TCP/IP. The TCP/IP protocols allow computers and devices to communicate with each other over the internet. The IP address, in this case, works like your door number that allows the mail carrier to recognize your house and throw the mail into your mailbox.
It is not hard to guess that IPv6 is the successor of IPv4. Why do you need to switch the IPv4 to IPv6 which could make your VPN no longer working? The question of why you should use IPv6. And your concern about IPv6 VPN will be explained as followed.
The difference between IPv6 from IPv4 is somehow simple & clear. As stated above, the function IP address plays during the process of internet telecommunication is like your resident address. The post office locates you through your address like your address is “university avenue 201, door 104, Murfreesboro, Tennessee”. In computer science domain, your device’s network address is present as a string of numbers. For example, Google’s server IPv4 address (public DNS server) is 18.104.22.168 and 22.214.171.124. with each number ranging from 0 to 255, so you got IPv4 address range from 0.0.0.0 to 255.255.255.255. So theoretically, the IPv4 address has it maximized limit of 4.3 billion IP address. So obviously as the internet grew and went global, the IPv4 addresses quickly ran out.
The IPv6 refers to Internet Protocol version 6, as you learn from its name, the IPv6 newer version which developed to replace the IPv4 in order to deal with the IP address drained out. Different from IPv4’s 4-number combined string, IPv6 addresses are, represented as eight groups of four hexadecimal digits & characters, with the groups being separated by colons. One example could be “2001:0db8:3c4d:0015:0000:0000:1a2f:1a2b”. With it’s top 128-bit design, the maximum number of IPv6 address can be distributed is about 340 undecillion (340,282,366,920,938,463,463,374,607,431,768,211,456 addresses). At present, IPv4 and IPv6 are coexisting on the internet, but in a presumable future, the IPv4 will be replaced by the IPv6 since the IPv4 address resources were already exhausted since the 1990s. That is to say, the change from IPv4 to IPv6 will change your internet use, most importantly, your VPN for Windows.

As stated above, both IPv6 and IPv4 are used alongside each other, but they are not compatible. For example, even if your device is IPv6 VPN supported and you’ve got an IPv6 IP address, you would not be able to connect to an IPv6 website if your VPN service provider does not support IPv6.
The problem for non-IPv6 VPN service providers is: most of them are not yet approved of an IPv6 connection. Since IPv4 still takes a huge portion of internet IP usage, also because IPv4 is a much cheaper & common solution. That means you are not able to visit the IPv6 websites and online resources with a non-IPv6 VPN tunnel. On the other side, because of newer technology was introduced to IPv6, the answer: “Is IPv6 faster than IPv4” is positive. When compare to IPv4, the IPv6 performs a better speed.
Most of the VPN services have fewer interests in IPv6 due to the economic concern – to replace, re-address their tremendous server resources will be a costly job to do, but not the iTop VPN. As one of the best free VPN for Windows, in order to provide the best service to their customers, iTop VPN upgraded their server to adapt the IPv6 connection. Thus users could use this fast VPN free for PC and mobile to visit any website online (both IPv4 & IPv6 are supported now).
Here’s the good news for iTop VPN for Windows users – You could now enjoy the IPv6 connection freely on iTop VPN. Now, IPv6 proxies have opened for U.S., Japan, Germany, and France tunnels. Remember the iTop VPN is a VPN that you can use without login. It will not affiliate any of your banking & payment information nor ask you to do the registering.

The post have explained the mechanic of IP address system in the above: since both IPv4 VPN & IPv6 VPN are your networking address with different presence, theoretically, it will have no time difference for traffics that travel through servers to locate your device since your address does not actually change. But considered the messy IPv4 address system is really outdated and it could possibly affect the effectiveness of network transmission. As IPv6 is a newer, well organized protocol system, it potentially performs better than IPv4 system undoubtedly. So you could say that the IPv6 VPN is faster than IPv4 VPN.
IPv6 is designed for end-to-end encryption, so in theory, widespread adoption of IPv6 will make man-in-the-middle attacks significantly more difficult. And the IPv6 over VPN also supports more secure name resolution and the newest encryption algorithm adopted. For example, The Secure Neighbor Discovery (SEND) protocol adds a security extension to the Neighbor Discovery Protocol (NDP). So an IPv6 encrypted VPN will be significantly securer than an IPv4 VPN, by all means.
As a conclusion, An VPN using IPv6 will be much safer than an IPv4 VPN which presented to users. And in a predictable future, the IPv4 protocol will gradually diminished from our vision and if you are not using a ipv6 VPN tunnel and you have such a need, the free VPN – iTop VPN could be a great opportunity for you to have a try!
