What are the differences between IPv4 and IPv6? We can understand the difference between IPv4 and IPv6 through the following, we will appear IPv4 and IPv6 when we connect the wireless network, then where is the difference between the two? Want to know friend please see below.

Most of us use the second-generation Internet IPV4 technology, its biggest problem is the network Address resource is limited, theoretically can address 16 million network, link 4 billion host. According to the relevant data, the global IPV4 IP address is about to run out.

The IPV6 is an IETF designed to replace the current version of the IP Protocol (IPV4) of the next generation of IP protocol, its IPV6 address length of 128 bits, the address space increased by 2 98 Times Square times, is almost inexhaustible. So with IPV4, the network that supports IPV6 is bound to grow.

Data statistics, some of the world's network developed countries have begun to use IPV6 instead of IPV4, this is the first in Belgium, its IPv6 ratio of traffic has accounted for 27%, higher than Germany (11%) and the United States (9.5%). Other European countries, such as Switzerland, Luxembourg, Romania and the Czech Republic, have also performed well, accounting for between 5% and 9%.

According to Google's statistics, 5% of the world's online use of IPv6, compared to last year, made rapid growth. Many colleges and universities are popularizing ipv6,ipv6 have larger address spaces, use smaller routing tables, and are more secure and allow expansion.

Of course, IPV6 is not a perfect solution, like IPv4, IPV6 will cause a lot of IP address waste, but also in the fight against DDoS attacks are flawed. But there are enough addresses in the IPV6 to assign a unique IP address to every square inch of the planet, and the advantage is unmatched, so replacing IPv4 is a trend.
