IP address basics & Terminals

  • General

Most networks today, including all computers on the Internet, use the TCP/IP protocol as the standard for how to communicate on the network. In the TCP/IP protocol, the unique identifier for a computer is called its IP address.

How does your computer get its IP address? An IP address can be either dynamic or static. A static address is one that you configure yourself by editing your computer’s network settings. This type of address is rare, and it can create network issues if you use it without a good understanding of TCP/IP. Dynamic addresses are the most common. They’re assigned by the Dynamic Host Configuration Protocol (DHCP), a service running on the network. DHCP typically runs on network hardware such as routers or dedicated DHCP servers.

  • Assigning static IP address to your computer

To change the computer’s IP address in Windows 7, type network and sharing into the Search box in the Start Menu and select Network and Sharing Center when it comes up. If you are in Windows 8.x it will be on the Start Screen itself, like the screenshot at the top of this article.

Then when the Network and Sharing Center opens, click on Change adapter settings. This will be the same on Windows 7 or 8.x.

Right-click on your local adapter and select Properties.

In the Local Area Connection Properties window highlight Internet Protocol Version 4 (TCP/IPv4)then click the Properties button.

Now select the radio button Use the following IP address and enter in the correct IP, Subnet mask, and Default gateway that corresponds with your network setup. Then enter your Preferred and Alternate DNS server addresses. Here we’re on a home network and using a simple Class C network configuration and Google DNS.

Check Validate settings upon exit so Windows can find any problems with the addresses you entered. When you’re finished click OK.

Now close out of the Local Area Connections Properties window.

Now you can open the command prompt and do an ipconfig  to see the network adapter settings have been successfully changed.

  • Usefull Tools

The most useful tool is a Windows command promt (cmd).

A command prompt is an entry point for typing computer commands in the Command Prompt window. By typing commands at the command prompt, you can perform tasks on your computer without using the Windows graphical interface.

To open the Command Prompt window, click the Start button Picture of the Start button –> All Programs –> Accessories, and then click Command Prompt.

1. To find out your current IP address settings, type “ipconfig” command and click “Enter“. The IP settings will appear.

2. To view the Address Resolution Protocol (ARP) cache, type “arp -a”. This will show all the IP and MAC addresses in your network.

3. To test and verify connectivity from the computer to some IP address, type “ping” command and then type a space and IP address you want to check connectivity to. For example: “ping 192.168.1.15

  • Finding & connecting IdentyTech terminals 

All of Identytech  are are shipped with the following IP settings:

IP address:       192.168.1.1

Subnet Mask:  255.0.0.0

Gateway:         192.168.1.1

If your network setting supports assigning of DHCP addresses, once you plug the terminal to the network, the IP address will be automatically assigned to the terminal.

In case the IP address was not assigned automatically, it has to be set manually. In order to do so, you will have to assign a “Static” IP address to your PC with the following :

IP address:       192.168.1.15

Subnet Mask:  255.0.0.0

Gateway:         192.168.1.1

(To assign a static IP please navigate to the top of the page to “Assigning static IP address to your computer” section.)

Once the address is assigned, you will be able to see the terminal in the management software and change its IP address to desired IP settings.
