PC Fixed IP Address

How do I set a fixed (static) IP address on my PC ?

The easist/quickest method of configuring your PCs for TCP/IP access is to use the router's DHCP facility whereby the PC is allocated its IP address and DNS/Gateway settings automatically by the router (on Windows, this is set as 'Obtain IP address Automatically' in the network TCP/IP properties).

However, if you wish to set your own local IP addresses manually (for example to run a local server which needs a fixed local IP address) then you can. You can mix automatic (DHCP) and manually set IP addresses on the same network as long as the 'manually' set IP addresses do not clash with the DHCP range and that all addresses fall within the same subnet.


Windows XP Network Connections

Select the TCP/IP protocol as shown below and click on 'properties' and then check that Manual selection of IP and DNS entries is selected. Enter your required settings as necessary. In this example we have chosen an IP address fot the PC as - ensure any manually allocated PCs are given addresses outside your DHCP allocated range and that you don't use the same address twice.

Set a Static IP address

Windows 98

From Windows 98 Control Panel, go to Network and highlightTCP/IP -> Ethernet Adapter and click the Properties button. Go to the IP Address tab :

Letís assume that weíve chosen to number our local PCís in the range 192.168.1.X where X is any number from 1 to 255 (that means our netmask will be as only the last octet varies). In this example weíve chosen this IP range because the router has a factory default address in that range (the router is numbered, but you can number your PCs within any range you wish, as long as you re-number the router to within the same range.

Click the Specify an IP address button as shown in the picture on the right, and give the PC a unique address (i.e. one not allocated to any other PC). If you were using Method 1, the button marked "obtain automatically" would be checked. In our example weíve given the PC an IP address of (remember that the router is already using by default). You could number the next PC, or etc., as long as the final octet (the bit after the 192.168.1.) is unique and in the range 1-255.

Next, click the DNS Configuration Tab, and enter your ISPís DNS addresses. The picture below shows an example, but you must use those for your own ISP).

If you prefer (and we do recommend it) you can still use the Vigor routerís DNS proxy facility. To do this, instead of entering real DNS server addresses as shown above, enter the routerís local IP address (default unless you have changed it). DHCP must be enabled on the router for the DNS proxy to be active but you can still manually configure the PCís IP address.

Finally, you need to set the Gateway IP Address. The Gateway is the Routerís local IP address Ė default is unless you have changed it. It is absolutely vital that you enter this !
