假如你的筆記本需要在家里和公司頻繁地進行IP地址切換，是不是很煩？而網上大量的切換工具對Win7均無效，怎么辦？請不要擔心，自己DIY一個批處理文件就行了。
注意，以下是針對IPv4進行的修改。
另外，安裝了360可能會有風險提醒，請大家不要擔心，放心點擊通過，此代碼毫無風險，童叟無欺，盡可安全使用。
首先，打開記事本，新建一個"IP切換.txt"，內容如下，
最后，把文件名改為"IP切換.bat"就大功告成了。
@echo off
rem //設置變量本地連接, 根據你的需要更改
set Nic="本地連接 3"
rem //可以根據你的需要更改
set Addr=192.168.1.11
set Mask=255.255.255.0
set Gway=192.168.1.1
set Dns=192.168.1.1
set Addr2=10.32.66.34
set Mask2=255.255.255.192
set Gway2=10.32.66.62
set Dns1=202.107.196.144
set Dns2=202.101.172.46
rem //以上對應分別是IP地址、子網掩碼、網關、首選DNS、備用DNS ，自己根據情況修改
rem //家里的DNS和公司一樣則可以用以上代碼，不一樣可能需要稍作修改

我使用的是JSF+Spring+Hibernate,在實現文件上傳時遇到了這個問題，每次上傳一個文件就會出現一次這個警告，但是似乎并不影響文件的上傳，文件還是可以保存到數據庫中相應的表中的。
想解決這個問題，但不知道從何下手個，希望能有高手指點一下。
