Why does my IP address change?

Every time people establish a new connection with their broadband Internet Service Provider’s (ISP) account either using a wired home / business connection or a wireless connection, the ISP’s network assigns an individual Internet Protocol to them. This is necessary for any computer in order to connect to the web and so that other web servers could provide the data exchange facilities.

There are two types of an IP address assignment – static IP and dynamic IP. Most broadband service providers use dynamic IP address allocation and offer a static Internet Protocol allocation at additional fee. Static IP assignment is often required for device tracking devices such as such as those used in IP address surveillance and those that require a permanent network address.
