import (
    "fmt"
    "encoding/json"
)

type Host struct {
    IP string
    Name string
}

func main() {

    m := Host{Name: "Sky", IP: "192.168.23.92"}

    b, err := json.Marshal(m)
    if err != nil {

        fmt.Println("Umarshal failed:", err)
        return
    }


    fmt.Println("json:", string(b))
}
