Simple Example 1: set a fixed IP address and save it as a bat file

@ Echo off
@ Rem: Set the IP address to 192.168.0.1, And the subnet mask to 255.255.0. The default gateway is 192.168.0.254.
Netsh interface ip set address local static 192.168.0.1 255.255.255.0 192.168.0.254
@ Rem set the preferred DNS server 192.168.0.254
Netsh interface ip set dns local 192.168.0.254
@ Rem add DNS server 202.106.196.115
Netsh interface ip add dns local 202.106.196.115 index = 2
