Changing DNS With A .bat File

[JakeC112]

Hi,

I am doing exams soon so I need to start studying. I have set up OpenDNS to block some websites that may distract me but I don't need them blocked all the time. As OpenDNS offers no settings for time to block I need to change the DNS server back to my ISP's when the blocking is not needed. The command to change DNS in Command Prompt is

"C:\Netsh Interface ip set dns "Local Area Connection" static "[DNS GOES HERE]"

But with a START command in front of it this command does not work when put into a batch program.

Does anyone know either a better way of changing the DNS at different times or the correct way to insert this command into a batch file.

Thanks
Jake

This may not be exactly what you want but you could always use your host file to redirect or simply block websites that may distract you.

Simply follow this tutorial. You don't have to use 127.0.0.1, which is your loopback address. You can use the IP address of say, a website you should be studying instead of your distractions

Simply erase the entries from the blocked files when you don't want them blocked.

Hi,

You change it by modifying your Registry files. It works like a charm for me.
(Make it .bat and start it)

reg add "HKLM\System\CurrentControlSet\services\tcpip\Parameters" /f /v "SearchList" /t REG_SZ /d "YOUR DNS"
reg add "HKLM\System\CurrentControlSet\services\tcpip\Parameters" /f /v "NV Domain" /t REG_SZ /d "YOUR DNS"
reg add "HKLM\System\CurrentControlSet\services\tcpip\Parameters" /f /v "Domain" /t REG_SZ /d "YOUR DNS"
reg add "HKLM\System\CurrentControlSet\services\tcpip\Parameters" /f /v "DhcpDomain" /t REG_SZ /d "YOUR DNS"

This will clear it up the record from the registry.

reg add "HKLM\System\CurrentControlSet\services\tcpip\Parameters" /f /v "SearchList" /t REG_SZ /d "" 
reg add "HKLM\System\CurrentControlSet\services\tcpip\Parameters" /f /v "NV Domain" /t REG_SZ /d "" 
reg add "HKLM\System\CurrentControlSet\services\tcpip\Parameters" /f /v "Domain" /t REG_SZ /d "" 
reg add "HKLM\System\CurrentControlSet\services\tcpip\Parameters" /f /v "DhcpDomain" /t REG_SZ /d ""

Good luck with you studying
F.

Don't use START.

Try this:

netsh interface ipv4 set dns name="Local Area Connection" static 8.8.8.8 primary
netsh interface ipv4 add dns name="Local Area Connection" 8.8.4.4
ipconfig /flushdns
pause
