When running Windows and you want a quick way to change DNS server, you can use a simple script in a *.bat file.
I have several DNS settings that I might want to use, depending if I the situation.
Where the “Ethernet” is the name of my network card name, change this if necessary.
When you want to change the DNS setting, just right-click, select run as administrator and you are done.
Script 1:
lan-dns-dhcp.bat netsh interface ipv4 set dns "Ethernet" dhcp ipconfig /flushdns
Script 2:
lan.dns-google.bat netsh interface ipv4 set dns "Ethernet" static 8.8.8.8 netsh interface ipv4 add dns "Ethernet" 8.8.4.4 index=2 ipconfig /flushdns
Script 3:
lan-dns-dhcp.bat netsh interface ipv4 set dns "Ethernet" static 208.122.23.23 netsh interface ipv4 add dns "Ethernet" 208.122.23.22 index=2 ipconfig /flushdns
