Static And Dynamic Using Linksys Router
UPDATE: A rewrite of this guide is up. The new guide explains it in more detail.
So i am pretty sure many of you have encountered this problem before. You are using a router to share internet connection amongst the various computers in your home/office and you want to configure it such that some of them have static ip while other computers have dynamic ip address. You might need static ip because you want to run a bit torrent client or a server application(vnc server, webserver etc). So how would you go about achieving it. For my explanation, i will be using the Linksys BEFW11S4. Most other routers should work in a similar manner. But the important thing is the idea behind it.
First, you must login to your router(for mine i enter 192.168.1.1 in my webbrowser address bar) and then a dialog box should pop up asking for your password. After this is done, you will see a window similar to this
Then click on the DHCP tab, which would bring up a screen that looks something like this
Since local ip address usually starts at 100(i.e it starts at 192.168.1.100 for mine), you will change the starting ip address depending on how many static ip u have setup. So if u have 3 computers and 2 of them have static ip, you can put in 192.168.1.102 under the "Starting Ip Address" field(or higher if you want but i am assuming you have as static ip 192.168.1.100 and 192.168.1.101 for those 2 computers). So when the other computers dynamically asks for an ip from the router, it will only hand out ip address that is 192.168.1.102 or higher. This achieves our goal of having both static and dynamic ip addresses.
Note:
- Difference between Static and Dynamic IP.
- If you wanna know how to setup static ip, microsoft has an article on it.
