<title>What is an IP address?</title>
<p>"IP address" stands for <em>Internet Protocol address</em>, and each device that is connected to a network (such as the internet) has one.</p>
<p>An IP address is similar to your phone number. 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 administering a server.</p></note>
