In_addr is the structure for storing IP addresses.Struct in_addr {U_int32_t s_addr;};Ifreq is a structure related to network interfaces./** Interface request structure used for socket* IOCTLs. All interface IOCTLs must have Parameter* Definitions

What is a socketThe socket interface is a TCP/IP network Api,socket interface that defines many functions or routines that programmers can use to develop applications on a TCP/IP network. To learn about TCP/IP network programming on the Internet,

The IP address we usually use is a string of the type 192.168.1.11, and an IP address expressed in binary format in the Linux kernel. In programming, the conversion between IP addresses in string expression mode and binary IP addresses is often used.
