反查IP或網域

網路連線發生不穩

如何看出哪一段線路慢了?

  • Windows: 開始 -> 執行 -> 輸入cmd (進入"命令提示字元")
  • (會顯示C:\某資料夾>)
請在閃爍游標處輸入 tracert web.domain.com (web.domain.com 改成想檢查的網站網址)
就可以看出是哪一段慢了,大家先作這個動作會有助於解決問題及增加回覆的速度喔

或者

請在閃爍游標處輸入 tracert web.domain.com > c:\result.txt
  • 當出現第二次C:\某資料夾> (如果網路連線不穩定, 會花費相當多時間)
代表已經將連線過程紀錄成功在 c:\result.txt
  • 請將這個文字檔寄給合適的網路管理員
