Address

Address

In computer science, "address" refers to the location of a specific piece of information, device or other item that can be accessed by computers.


The most common system used for addresses on the Internet are IP addresses that use a series of four numbers, separated by dots. An example would be: 127.0.0.1


Each computer or device on that network will have a unique "address" that is known by the other computers and devices in the network. Your own personal computer will also have a unique address that it uses for interacting with the various resources on the Internet.


When you use your browser to request a web page from a web server, the web server usually makes a record of what computer asked for the web page, what web page was requested, and whether or not the web page was successfully sent to the requesting computer. The record will contain, among this other data, the IP address of your computer.


Additionally, your internet service provider (ISP) stores who was using what IP address at a particular time. Under an existing law, ISPs are required to retain records for 90 days upon request of a "government entity". They will usually keep that records 3 to 9 months.
