Thread: Assigning static IP address

I am not the network aware poster on this forum, but I was wondering what process you are using to set the IP addresses?

Have you looked into using Powershell to change the addresses and possibly there would be a way to script the actions you need?

I know you can start the Powershell Admin window by using Winkey and typing Powershell then CTRL+Shift+Enter. Or you could just attach it to the Taskbar or Start. I have found some references to changing IP Addresses using Powershell and will give you one that might be a good place to start.

Someone else on the forum might be able to give you an efficient way to do what you need.

How to Change Your IP Address Using PowerShell

I have just been going through the control panel to change IP settings.

I haven't tried this either, but could you set up 3 or 4 network connections in the Network Connections panel? It appears, each name would have different configurations so you could enable or disable the ones you needed?

But the "name" of my network adapter is always "local area network". I just open control panel > Network > right click on "local area network" > Properties > ipv4 and set a static IP address. I didn't even know the ip addresses were "sticking" until I plugged into a clients network, thinking I was DHCP to get a IP conflict message. Doing a ipconfig from the command line let me know I the adapter still had about 4 ip addresses from previous customer sites.

Static assigned IP addresses are not allocated on a "lease" basis as are DHCP allocations - they are assigned manually and remain so until "released" manually. You can do this from a command prompt using the ipconfig command. Once released setting DHCP allocation will allow the adapter to obtain a new address automatically. The release command may or may not be optionally supplied with further parameters - this basic from will release all IP addresses from all adapters

ipconfig /release

To release the address from a specific adapter you can add the name of the adapter, eg:

ipconfig /release Local Area Connection 1

You may also use "wildcards" to release a group of addresses, eg:


ipconfig /release Local*

will release addresses from all adapters starting with the word local.

I understand all of the above. ipconfig /release has no effect. Reboots, both warm or cold have no effect. The only way I have found to clear the old ip addresses is to remove the device and reboot. Upon reboot, the device is back and in dhcp mode.

Just to check - you have tried executing a release for specific named adapters as well as for all?

Just realised, we have not mentioned setting the "obtain an IP address automatically" on the adapter properties - it this a case of missing the obvious - have you in fact done that to go from static to dhcp?
