Internet Protocol version (IPv), also known as Internet communication protocol, is a public protocol in the development process of Internet Protocol. There are two widely used protocols, IPv4 and IPv6. So which one should I choose between ipv4 and ipv6? The following article will introduce it to you.

Which one should I choose between ipv4 and ipv6?

Most of us are using the second generation Internet IPv4 technology. Its biggest problem is the limited network address resources. In theory, it can address 16 million networks. , linking 4 billion hosts. According to relevant data, the global IPv4 IP addresses are about to be used up.

IPv6 is a next-generation IP protocol designed by IETF to replace the current version of IP protocol (IPv4). Its IPV6 address length is 128 bits, and the address space is increased by 2 to the 98th power, almost It can be said to be inexhaustible. So with the shortage of IPv4, the number of networks supporting IPv6 is bound to grow.

According to statistics, some countries with developed networks in the world have begun to gradually replace IPv4 with IPv6. Belgium is at the forefront in this regard. Its IPv6 traffic proportion has accounted for 27%, which is higher than that of Germany (11 %) and the United States (9.5%). Other European countries, such as Switzerland, Luxembourg, Romania, and the Czech Republic, also performed well, accounting for between 5% and 9%.

According to Google statistics, 5% of the world's networks already use IPv6, which has achieved rapid growth compared with last year. Many colleges and universities are popularizing IPv6. IPv6 has a larger address space, uses smaller routing tables, is more secure, and allows expansion.

Of course, IPv6 is not a perfect solution. Like IPv4, IPv6 will also cause a large amount of waste of IP addresses, and it also has flaws in resisting DDoS attacks. However, there are enough addresses in IPv6 to allocate a unique IP address to every square inch of the earth. This advantage is unmatched, so replacing IPv4 is also the general trend.
