Your phone number is a unique set of numbers that identifies your phone so that other people can call you. Similarly, an IP address is a unique set of numbers that identifies your computer so that it can send and receive data with other computers.</p> <p>Currently, most IP addresses consist of four sets of numbers, each separated by a period. <code>192.168.1.42</code> is an example of an IP address.</p> <note style="tip"> <p>An IP address can either be <em>dynamic</em> or <em>static</em>. Dynamic IP addresses are temporarily assigned each time your computer connects to a network. Static IP addresses are fixed, and do not change. Dynamic IP addresses are more common that static addresses — static addresses are typically only used when there is a special need for them, such as in the administration of a server.</p> </note> </page>
