To find the IP range on a network, or to find available IP addresses, follow the steps below.
Windows
Finding the IP Range of a Network
This is useful if you are unsure what the network details are, or if you have requested pre-programming. When pre-programming devices, we require these details.
1. Connect a Windows PC / Laptop, open the start menu and type cmd.
2. Launch the Command Prompt program.
3. Once it opens, enter the command ipconfig and take a screenshot or copy the information as below. We require the IP address, Subnet Mask and Default Gateway.
4. A screenshot can be taken by pressing the Windows + Shift + S keys simultaneously, then paste it into a document/email with Ctrl + V
Finding Available IP Addresses
If you wish to connect devices to the network for remote access, you must give each device an IP address, within your network range. In this example, we will be using a Windows computer which is connected to a modem to find the IP address of the computer, and available IP addresses to use for the devices. If the devices are being installed on a business or managed network, contact an IT representative for assistance.
1. Connect a Windows PC / Laptop, open the start menu and type cmd.
2. Launch the Command Prompt program.
3. Once it opens, enter the command ipconfig and take a screenshot or copy the information as below. Note down the IP Address, Subnet Mask and Default Gateway.
4. In our example, the IP address is 10.0.0.61. To check what IP address is available, type ping 10.0.0.XXX, where XXX is any number between 2 and 254. If Destination host unreachable or Request timed out is show on screen, there is no device using that IP address. Repeat the process to find multiple IP addresses that are available for use. Every devices requires one IP address. 10.0.0.XXX is used as an example, you the IP Address range will vary depending on the network.
5. When configuring the devices, use the IP addresses that you have found that are available, making sure each device has a unique IP address. The Subnet Mask and Default Gateway, will be set the same on each device.
