While development and testing many times we need to change the IP addresses manually
to a given IP and then switch back to Dynamic IP (DHCP). Doing it everytime through
GUI especially in Vista (finding the Network Option from Start, Right Click, Selecting
Network Connections, then Right Click on the Interface, Choose IPV4, ...) is tiresome
and waste of time.
For doing it easily Windows exposes a great command called NETSH. NETSH exposes
too many options, the help (/?) and online documentation runs for several pages. Because
of this, everytime I tried I was put off. Today I spent last 5 minutes and cracked
this. For changing IP address, we need to use the NETSH
INTERFACE IP command.
To display current IP settings (equivalent to your ipconfig command):
C:\>netsh interface ip show addresses
Configuration for interface "Local Area Connection"
DHCP enabled:
No
IP Address:
10.10.99.222
Subnet Prefix: 10.10.0.0/16
(mask 255.255.0.0)
Default Gateway: 10.10.10.11
Gateway Metric: 256
InterfaceMetric: 20
To change your IP Settings to DHCP:
C:\>netsh interface ip set address name="Local Area Connection" source=dhcp
To set IP to a manual config (replace with your own values):
C:\> netsh interface ip set address "Local Area connection" static 10.10.9.22 255.0.0.0 10.10.10.111
1
Here after static command, the first value is your IP Address, second is NetMask,
third is Gateway and fourth is metric.
Similar to set address command in netsh interface ip there
is set DNS command that can set the DNS values as well. If you put
the above in a batch (.bat) file then you can just double-click on it everytime you
want the IP config to be changed.
