inside/outside the dmz

By tony.jansson ·
We have installed a LAN in our neighbourhood. The ISP charges for the connection directly to the Internet backbone but not for servers inside the DMZ or WAN:s connected directly to the DMZ like Sunet (Swedish University Network). So if I download anapplication from e.g. a server in Sunet it does not affect the statistics and the ISP will not ask to charge us for a faster connection. There is a cgi-script at the ISP:s server where we can check if a site is within the DMZ. However most people won't take the trouble to check this. Is there an applet that can be used in a frame or in a Netscape sidebar to tell you if a net adress is inside or outside the DMZ, while your surfing, e.g. by hovering your pointer above the adress in a search result?

By referring to the DMZ, what exactly are you referring to? Where I work, the DMZ is usually referring to the "De-Militarized Zone", which is the small lan of webservers and data servers which lies outside of the main company firewalls.

DMZ is the term used by the ISP, but they use it to cover the area that they don't charge us for, I suppose they believe it's easier to grasp for the end user. Connected to the DMZ is the Swedish University Network (Sunet), the local council in our town and an adjacent town, the university, the hospital and several companies and then finally there is a gateway to the Internet. That's the connection they charge us for. And we're obliged to keep within certain limits otherwise they will charge us for a faster connection. To give you an example, I downloaded a large file from java.sun.com. That download went straight into my statistics, but if I had found it within the "DMZ"/"free area" it wouldn't have shown up on the statistics. I suppose the "DMZ check", that we can do on the ISP:s server is compared to a list of IP:s and it is probably possible to get hold of that list.

I know of no such utility created for the purpose you seek. Unfortunately, you would not be able to use a java applet because ti would run in its own window and owuld not be able to detect mouse-over events in another window. The same thing happens with a program. Unless the code is pugged into the browser, it would be extrememly difficult to develop a program to grab the address from the mouse over.

Once you have the internet address, it would be a very simple matter of resolving the hostto an IP and comparing that IP against a list of IPs/hostnames that your ISP should provide you with and then outputting a message based on whether it is found in the list or not.

The programming is too time consuming to be worth the trouble for this particular application. I apologize if that is not the answer you wanted but its the truth.

I'm beginning to understand how difficult it would be to create an applet that would do this. One solution would be to find a search engine with a syntax that can do this, but I know of no such search engine. Another would be to manipulate the browsers URL-history in some way, but then we're talking about solutions that are too difficult for the end-user (including myself). Thanks anyway for clearing that out for me.
