The Google chart above shows countries where IPv6 is more widely deployed (the darker the green, the greater the deployment)
The most active countries using IPv6 protocol are Belgium (53.71%), Germany (40.16%), India (36.81%) and Greece (36.72%). The United States (34.14%), Uruguay (31.93%) and Malaysia (32.03%) are slightly behind with Canada, France, Finland, Brazil, the UK, Estonia and even Peru following. In the CIS, IPv6 is almost never used. Furthermore, it is important to note that Google has a weak presence in China and information regarding IPv6 adoption in China is not relevant.What is The Difference Between IPv6 and IPv4?
The transition to IPv6 is inevitable as IPv6 has some advantages over IPv4. For more information, please see IPv4 limitation details
.Advantages of IPv6 over IPv4:
• More efficient routing without packet fragmentation
• Integrated Quality of Service (QoS) technology, which identifies delay-sensitive packets
• Built-in IPsec support (optional use of IPsec)
• Autoconfiguration of addresses to simplify network administration
• Improved header structure with lower processing costs
• Increased data security
Why not just switch to IPv6? The answer is cost. It takes a great deal of money and time to upgrade all the servers, routers and switches that depend only on IPv4. Despite the problems associated with the transition to a new version of Internet Protocol, this is an important and significant step for everyone, without exception. The transition to IPv6 is inevitable. It proceeds slowly, though, because the benefits of innovation are not obvious, at the moment, for most users. The first to come onboard are those countries where the shortage of addresses is felt the most acutely. In the meanwhile, we have to stick to IPv4 and Carrier Grade Network Address Translation (CGN or CGNAT
), also known as Large Scale NAT (LSN) that extends ipv4 while enabling IPv6.
