How to do it...

1. Open the console and create the folder chapter07/recipe01.
2. Navigate to the directory.
3. Create the interfaces.go file with the following content:

        package main        import (          "fmt"          "net"        )        func main() {          // Get all network interfaces          interfaces, err := net.Interfaces()          if err != nil {            panic(err)          }          for _, interf := range interfaces {            // Resolve addresses            // for each interface            addrs, err := interf.Addrs()            if err != nil {              panic(err)            }            fmt.Println(interf.Name)            for _, add := range addrs {              if ip, ok := add.(*net.IPNet); ok {                fmt.Printf("\t%v\n", ip)              }            }          }        }

4. Execute the code by running go run interfaces.go in the main Terminal.
5. You will see the following output:
