Different picture seen for different IP addresses

by vmo / February 9, 2004 10:40 AM PST

I want to be able to show a picture on a website. But I also want that picture to change on the website depending on the ip address of the viewer.

Ex: House 1 viewing the website would see Pic 1
House 2 viewing the same website would see Pic 2.

Any help would be appreciated.

Without background on the webserver capabilities or if you want to hardcode such into Java I can see some hundred solutions. Nothing specific as to what your answer will be since I don't know if you do CGI, Java or "other."

Before I write further, my policy is I don't write code for non-GNU projects for other people unless they pay me. So don't ask for code.

I will however supply fishing lessons and directions, but no "fish."

With that disclaimer, look at a prime example of how some swap BANNER ADS?

With millions of ip addresses, how do you hope to track who belongs to what ip?

Anyway, you can use java/javascript tricks to get a users ip. Here's an example:

if (navigator.javaEnabled()) {
userDomain = java.net.InetAddress.getLocalHostName()
return (userDomain.toString())

if (navigator.javaEnabled()) {
baseAddress = java.net.InetAddress.getLocalHost()
userDomain = baseAddress.getHostName()
return (userDomain.toString())

Once you have the ip, simply use string functions like userDomain.split(".") to obtain the parts that you need.

The rest is easy, otherwise you need to learn javascript first.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
