What is the general IPv4 address?

The ipv4 address is generally 192.168.1.86.

Internet Protocol version 4 (English: Internet Protocol version 4, IPv4), also known as the fourth version of the Internet Communication Protocol, is the fourth revised version of the Internet Protocol in the development process, and it is also the first version of this protocol to be Widely deployed version. IPv4 is the core of the Internet and the most widely used version of the Internet Protocol. Its successor version is IPv6. Until 2011, when the IANA IPv4 addresses were completely exhausted, IPv6 was still in the early stages of deployment.

IPv4 is described in RFC 791 published by the IETF in September 1981, which replaced RFC 760 published in January 1980.

IPv4 is a connectionless protocol that operates on the link layer (such as Ethernet) using packet switching. This protocol delivers packets on a best-effort basis, meaning that it does not guarantee that any packet will reach its destination or that all packets will arrive in the correct order without duplication. These aspects are handled by upper-layer transport protocols (such as Transmission Control Protocol).

IPv4 is the abbreviation of Internet Protocol version 4, which represents the fourth version of the IP protocol. The vast majority of communication traffic on the Internet is encapsulated in the format of IPv4 data packets. IPv4 is described in detail in IETF publication RFC 791.

IPv4 uses 32-bit binary addresses, so there are only approximately 4.3 billion addresses. Initially, every user connected to the Internet must be assigned an IPv4 address, so there are fewer and fewer unallocated IPv4 addresses, resulting in the problem of IPv4 address exhaustion. In order to fundamentally solve the problem of IPv4 address exhaustion, IPv6 came into being.

IPv4 is usually written in dotted decimal notation, such as 192.168.0.1, where the numbers are all decimal numbers separated by solid dots.

An IPv4 address can be divided into two parts: the network address and the host address. The network address can be described in the following form: 192.168.0.0/16, where the number after the slash indicates that the length of the network address part is 16 bits. , which corresponds to 2 bytes, that is, the network address part is 192.168.0.0.

The specific differences between IPv4 addresses and IP addresses are as follows:

1. IPv4 is a version, and IP is a big concept. They have essentially the same difference.

2. The IPv4 address is the intranet IP of the radio and television network.

3. The difference between Class A, Class B, and Class C addresses in IP addresses. The length of the IP address determines the address space of IPv4 and the limit of the address.

4. IP includes private IP, public IP, IPv4, and IPv6.
