When to use a Static IP Address?

Assigning a computer a Static IP Address allows the PC to use the same IP address every time.

When you configure a wireless computer to automatically get an IP address, the computer will get an IP address from a DHCP server. Performing this procedure will ensure the computer will get the correct TCP/IP settings.

Assigning a computer a Static IP address is useful when:

- Setting-up public services on your computer (FTP servers, Web servers, etc.).

- The computer is frequently accessed on the network so that the computer can be easily mapped       

How to assign a Static IP Address on a wired computer?

Follow the steps below in sequence. Further down this article, the steps are divided by Windows 7, Windows Vista, Windows 2000/XP, Windows 98/ME and Mac.

1. Connecting Devices Together     

Ensure that you have an Active Internet Connection then connect the modem to the router's Internet port and the computer to any of the four Ethernet ports. For instructions, click here.

2. Checking if the Computer is Set to DHCP

To configure a computer to get an IP address automatically, you have to check the TCP/IP properties of the Ethernet Adapter installed on the computer. For instructions, click here.

3. Checking the Router's IP Address

To find a Linksys router's Local IP address, you have to check the IP settings of the computer. For instructions, click here.

4. Checking the DNS Servers From a Linksys Router

To check the DNS server on a Linksys router, you have to access the router's web-based setup page. For instructions, click here.

5. Assigning a Static IP Address on a Wired Computer

Click on the other operating systems you are using for a guide to assign Static IP Address.

Windows Vista

Windows 98/ME

Mac

Windows 7

Step 1:
Click on the Start icon . Next, click Control Panel.

Step 2:

Step 6:
Select Use the following IP address and enter the following:

NOTE: Make sure you have the Default Gateway and DNS servers.

Make sure the IP Address you'll be assigning the computer has the same first 3 numbers as the Default Gateway and the last number can be any number between 2 and 99. In this example, our Default Gateway is 192.168.1.1, so the IP address that should be used must start with 192.168.1. Next, place any number from two to 99.

In this example, the IP address that we'll assign is 192.168.1.50.

NOTE: For each additional computer that will be assigned a Static IP address, make sure it's assigned a unique IP Address.

IP: "192.168.1.50"
Subnet Mask: "255.255.255.0"
Default Gateway: "192.168.1.1" (This is the Default Gateway you wrote down earlier)

Select Use the following DNS Server addresses in the same window. Then, fill in the following fields:

Preferred DNS server: (this should be the DNS you wrote down earlier)
