We are actually using IPV4 now, that is, dividing the IP address into four segments. You can use general IP address software, such as 2.83.66. 108, to check the IP address of your computer. The maximum value of each segment in this format is 256. The so-called exhaustion of IP addresses means that these addresses have been allocated. It is often heard that the telephone number of a place is upgraded from seven digits to eight digits, because the number of telephone applications is too large, and the original seven digits are not enough. The solution to IP address exhaustion is upgrading, and the format of IPV6 is six segments to meet the needs of future networks. Because the distribution relationship of ip address protocol is actually the same as the gap between the rich and the poor, because the population in Asia is developing, the address display is insufficient. In fact, African countries still have many IP addresses to allocate. Internet address, that is, IP address, is a logical address used to identify Internet terminals, which is unique and equivalent to the house number of home address in life. The existing IP address of the Internet is a 32-bit address called IPv4, with a total capacity of about 4.3 billion!
The exhaustion of IP address refers to the exhaustion of IPV4. Wu Jianping, director of Tsinghua University Information Network Engineering Research Center, said that the exhaustion of IPv4 network address resources will not have any direct impact on China netizens. The biggest challenge is operators. Because there is no new address, it means that operators can only use the new IPv6 address to build a network, so that new netizens who use IPv6 addresses can connect to the IPv4 network smoothly in the future. Therefore, in 2003, the State Council approved the launch of China's Next Generation Internet Demonstration Project (CNGI), including six experimental networks based on IPv6 technology and 100 demonstration projects.
