It has been 20 years since IPv6 was implemented, but though it is more reliable, it’s not widely used as it has been expected. Network researchers are warning that IPv4 addresses aren’t endless, and the question is ‘’Why did IPv6 deployment reach only 17% in 2018?’’.

So, let’s find out why it’s high time to use IPv6 and what you need to remember when planning it.

IPv6 vs IPv4: which is better?

It is commonly known that IPv4 is based on a 32-bit scheme that provides with about 4 billion addresses, while the latter, which uses 128-bit addresses, provides with a far larger number of them (3.4×1038). With the high increase of the Internet, IPv6 offers more addresses that will ensure all members with unique addresses.

Lots of Internet Service Providers have already been offering IPv6 addresses, and nowadays, most devices support both versions. On Windows, for example, one can configure which version to use, but it’s worth noting that it’s necessary to find out if your ISP supports IPv6, otherwise, you’ll stay disconnected.

If you wonder what Internet protocol is now supported by your ISP, you can do it with the help of “What’s my IP?” tool that will identify your current IP address after a few clicks. Besides, find out more information at your ISP as both protocols are sometimes supported.

Another benefit which sounds reasonable nowadays is the advanced IoT security provided along with IPv6 scalability.

Why IPv6 is vital for web security

Firstly, IPv6 provides end-to-end encrypting which is universal and applied as a standard component. IPv4 can also be encrypted, but it’s an optional configuration. IPv6 encryption is now accessible for all devices and modern devices, which makes it more difficult for hackers to attack.

Secondly, IPv6’s SEND protocol applies encrypted confirming of the host. This makes it more difficult for an attacker to interfere in connections and monitor or influence them. Unfortunately, such attacks are easier to perform with IPv4 addresses.

Taking into account the reasons above, implementing IPv6 will bring more security to the global network.

When it’s necessary to change IPv4 into IPv6

As you can see, the question is not ‘’if it’s necessary to move to IPv6’’, but ‘’when to start implementing IPv6?’’. Among the first who started moving to IPv6 are ISPs and network carriers. And the mobile network is the leader now.

According to Alexa, 17% of top million websites work with IPv6 Internet protocol.

It’s high time for other business areas to ‘’join’’ this movement as well. There’s no exact date when IPv4 addresses stop running, but one day it will take place.

3 tips to remember when implementing IPv6

Don’t forget about the following list of measures when you decide to use IPv6 instead of IPv4 addresses:

  • Use tunnels carefully in case your network is IPv4-based, and tunneling is necessary for partial IPv6 implementing. Turn to tunnels only if it’s extremely necessary as traffic tunneling makes it easier for a security system not to define attacks.
  • Be sure that the structure of your network is compliant with IPv6. In case it isn’t, update the firmware of all devices connected to it.
  • Change the structure of your network. IPv6 differs from the one based on IPv4. That’s why to get better performance, you should think of how to improve it.

Finally, it’s obvious that IPv4 is getting out of date, and its successor IPv6 is far more advanced for the whole global web space.

Keep yourself safe and don’t forget to protect it!
