IPv4 is the English abbreviation of Internet Protocol version 4 (Internet Protocol version 4), and the Chinese abbreviation is "Internet Association Version 4", which is our The public network segment currently in use. The protocol family adopted by the current global Internet is the TCP/IP protocol family. IP is the protocol of the network layer in the TCP/IP protocol suite, and is the core protocol of the TCP/IP protocol suite. Most of today's Internet uses the IPv4 protocol. The IPv4 protocol has been used for more than 20 years. During these 20 years of application, Internet applications have achieved great success. Crises that cannot be ignored There are two major crises lurking in the existing IPv4 network: address exhaustion and routing table expansion. Although private network addresses (NAT technology) can be used to make up for the lack of IP addresses, classless inter-domain routing CIDR can be used to expand network numbers, and hierarchical addresses can be used to suppress the growth of routing tables, these temporary mitigation measures are accompanied by The negative impact cannot fundamentally solve the above crisis.
