Before starting about what IPv6 basically is, let us give you a brief detail about how content delivery networks usually work.
CDN is a globally distributed network of servers, which mostly functions together, for the sake of extending the speed of content delivery over the internet.
Internet protocol is a method through which one can easily send data from one computer to another over the internet, and till date, there are two versions of internet protocol available. IPv4 and IPv6.
IPv6 is the recently revised version of the Internet Protocol.
As IPv4 is now not able to provide the number of IP addresses required, thus IPv6 would be a much better option and also a safer one for your business,
And here are some of the reasons why one should use IPv6 CDN for their business and can get it from BelugaCDN.
What's CDN IPv6?
IPv6, as mentioned earlier, is the latest internet protocol which is designed specifically to replace IPv4. IPv4 has the network shortage of addresses because of which the need for more addresses aroused. Now with IPv6, the addresses are 128 bits that are 16 bytes long, and it is also one of the significant differences in the number of available IP addresses between IPv4 and IPv6.
IPv4 had 4.2 billion addresses available. But as everything is connected over the internet nowadays, the need for more and more IP address came out. Thus, with IPv6 there are 2 to the power of 128, because of which the available number of addresses will be quite more.
As all the devices have to be connected online like, any household appliances, cars, IoT devices, and even a growing number of mobile phones, The requirement of IP addresses is now more than ever.
The best part about IPv6 is that the leading zeros can be truncated as IPv6 addresses can be written in compressed or uncompressed and also in fully uncompressed modes.
Benefits of IPv6 CDN?
The adoption rate for IPv6 is growing tremendously and moreover, it is expected that it will continue to grow more quickly over the next few years.
Google's IPv6 adoption graph clearly shows an uprise in the adoption rate of this protocol. And the percentage of Google users who are accessing Google over IPv6 is almost 25% as of November 2018.
IPv6 just doesn't limit itself for the number of addresses, but even there are various additional benefits of IPv6's success, some of them are:-
Through IPv6 one can experience more efficient and simplified routing, and it's also considered as one of the major reasons behind the growth. Better multicast routing is also possible with this internet protocol.
Secondly, IPv6 allows auto-configuration because of which the ability to manage becomes quite easier. Which results in no need of DHCP.
Also one can experience better transparency, for every device
The best part about IPv6 is there will be no more duplicate IP addresses, thus making everything more secure and transparent to the users.
Even IPSEC is built into IPv6.
The header formats are more simplified than ever and even with IPv6, the delivery of contents is very fast.
The "True quality of service (QoS)", also popularly called as "flow labelling" can be experienced in IPv6.
Built-in authentication is one of the amazing features of IPv6 and even privacy support makes it one of the most efficient protocols.
There are flexible options and extensions available because of which Administration becomes very much easier.
Differences between IPv4 and IPv6:-
There are major improvements which are seen between IPv6 when compared with IPv4. Below are some of the major differences which are seen over both the protocols:-
Increased Address Space - Address Space is considered as one of the most important aspects of IPv6. As IPv4 address size is just 32-bit number that is 232, which resulted in just 4.2 billion IP addresses. And because of more demands of IP Address, the need for a more secure internet protocol came in the picture. Comparatively, IPv6 uses a 128-bit number that is 2128 which undoubtedly provides many more IP addresses, approximately 340 undecillion or even 36 zeros.
Improved Header - The header in IPv6 been simplified thus all the various options and unnecessary information is now moved to the bottom of the header which gives more clarity. And also the IPv6 header is double the size of IPv4s header.
Faster Forwarding / Routing - Because of the improved header in IPv6, it even allows routers to perform faster routing decisions, as all the important information is located simply at the top.
Anycast Support - IPv6 even supports Anycast mode of packet routing which enables multiple machines to get associated with the same IP address, because of which routers can send a packet to the nearest destination.
Extensible - IPv4 just provided only 40-bytes for options, but with IPv6, there is an option for extensibility which allows the users to extend the protocol which doesn't even affect the core packet structure.
Improved Mobility - Because of IPv6, it became easier for users to use their mobile devices in any geographic regions, without changing their IP address.
As far as the IP address is concerned, there is a large difference in the formatting of IPv6 when it's been compared to IPv4 addresses. A better example for this is IPv4 address looks similar to 188.8.131.52, but in the case of IPv6 address, the address may resemble fdc5:7a8b:5908::/42. So, while writing any IPv6 address one can even omit the leading zeros.
Transitioning From IPv4 to IPv6.
The transition from IPv4 to IPv6 may take some time. Although many services have already adopted and implemented IPv6 support, and also some are in the process of adopting the same.
But with the increasing availability of so many devices and services online, the completion of this process will obviously require more patience and time. However, with the help of multiple transition mechanisms, one can even simultaneously operate both the protocols to ensure a slow and smooth transition between IPv6 and IPv4.
