## Usage

```go

package main

import (

    gin "github.com/gin-gonic/gin"

    limit "github.com/bu/gin-access-limit"

)

func main() {

    // create a Gin engine

    r := gin.Default()

    // this API is only accessible from Docker containers

    r.Use(limit.CIDR("172.18.0.0/16"))

    // if need to specify serveral range of allowed sources, use comma to concatenate them

    // r.Use(limit.CIDR("172.18.0.0/16, 127.0.0.1/32"))

    // routes

    r.GET("/", func (c *gin.Context) {

        c.String(200, "pong")

    })

    // listen to request

    r.Run(":8080")
