This how to guide will cover setting up a static IP address on Windows Vista. It is very important to setup a static IP address if you are going to use port forwarding. With port forwarding setup your router forwards ports to a specified IP address. Anytime you restart your computer it may get a different IP address and the ports will no longer be forwarded to the originally specified IP address and the port forwarding configuration will not work. This is why you need a static IP address that will never change even after restarting your computer. We will now show you how to setup a static IP address.
Step 1: Go to the start menu and select “Run.” This should open a window like the one pictured at left. Type command in the “Open” field and click “Ok.”
Step 2: The command prompt window should now open. Type ipconfig/all in this window and hit the enter key. A lot of information should now be displayed in the window.
Step 3: Write down the IP address, Subnet Mask, Default Gateway, and Name Servers. Make sure to note which is which. We are going to use this information a little bit later. We are only concerned with IPv4 entries, you can ignore the IPv6 entries.
The name server entries are a bit complicated. Name Server is just another name for DNS(domain name server) server. Some router’s act as a proxy between the actual name servers and your computer. You will know when this is the case, because the Default Gateway will list the same IP address as the Name Servers entry. We need to have the correct Name Server IP addresses. If we do not, you will not be able to browse the web. There are a couple ways to get these. The first way is to log into your router’s web interface, and look at your router’s status page. On that page you should see an entry for DNS Servers, or Name Servers. Write down the IP addresses of your Name Servers. Another way to get the correct Name Servers to use, is to give your ISP a call. They should know the IP addresses of your Name Servers right off. If they ask you why you need them, you can tell them you are trying to setup a static IP address on your computer. If they try to sell you a static external IP address, don’t buy it. That’s an entirely different thing than what you are trying to setup.
Type exit in the command prompt window, then press the enter key to close it.
Step 4: Return to the start menu and open the Control Panel. In the Control Panel window, double click the “Network and Sharing Center” icon.
Step 5: In the “Network and Sharing Center” window, select “Manage Network Connections” from the left side of the window.
Step 6: Right click on the network connection you use to connect to the internet. If there are multiple network connections and you are unsure of which one to select, right click it and then click disable. Open a new copy of your web browser. Did it open a webpage? If you can not connect to the internet, then you’ve found your internet connection. Close that browser window. Go ahead and right click the network connection again and then click enable. Once again open up a new web browser. You should see a webpage. Close the browser window. Once you have found your network connection, right click on the network connection and click properties at the bottom
Step 7: You should now see a window like the one to the left. Click on “Properties” at the bottom of the window.
Step 8: Click Internet Protocol(TCP/IP) and then the Properties button.
Step 9: In this window you should see a dot in the Obtain an IP address automatically box. If you do not, your connection is already setup for a static IP and you don’t need to do anything further.
Pick an IP address and enter it into the IP Address box. The IP address you choose should be very similar to the router’s IP address. Only the last number of the IP address should be different. For example, if the router’s IP address is 192.168.1.1, you might choose 192.168.1.10. The IP address you choose should end with a number between 1 and 254, and should not be the same as the router’s IP address. Every device that connects to your network needs to have it’s own IP address.
Put the subnet mask we previously found in the subnet mask section. The default gateway should go into the Default gateway box. Enter the dns servers we prevoiusly found into the two DNS Server boxes. Click okay all the way out of this menu.
If you find that you can not pull up webpages, the problem is most likely the dns numbers you entered. Give your ISP a call, and they will be able to tell you which dns servers to use. This is a question they answer all of the time. They will be able to tell you what you should use right away.
You are now setup with a static IP address. If you have any trouble connecting to the internet simply return all the settings to default.
