Tracking IP addresses

Does anybody know if it is possible to track an IP address in order to know where it is from? If I remember well, the IP addresses are distributed in an organized manner to the countries and each country has its internal regulation bodies responsible to assign the addresses to the entities and...

Is it possible to conect two modems directly?

glugglug, the X3 command (blind dialing) is universal and I am sure that all modems do support it. Regarding placing it in the dialing string, I am also sure that there is no problem with it, considering that you place the commands in the correct sequence, because they are executed in sequence...

Is it possible to conect two modems directly?

prosaic, the sounds that I heard are typical when you type the commands ATA and ATX3D. Even with the phore wire disconnected from the jacks, those sounds occur. I am sure that these sounds are not the called "endless spiral of retraining to lower speeds", because no negociation started between...

Is it possible to conect two modems directly?

Is it possible to conect two modems directly?

hummmm... very interesting. A circuit simulating the electricity provided by the phone lines. It makes sense. But I am not absolutely sure if this is necessary, I mean, if the modems really need this external electricity to operate.

Is it possible to conect two modems directly?

Lets suppose that you want to make a file transfer between two PCs that don't have an ethernet adapter or a serial-to-serial cable, only 56K modems built in. I would like to know if it is possible to connect directly the two modems by using a conventional RJ-11 cable. I am wondering if there is...

Building up a LAN gaming house

Maybe... but comparing the GF2 GTS to a GF4 MX44O, I still think that the last is a step ahead in terms of generation and runs cooler (even without fan = maintenance free). What about Radeon value line? Nothing as value as a GF4 MX440 offering the same performance?
