<h2>A shared way to find computers</h2>
<p>Early packet networks connected only a few research computers. When independent networks started communicating, they needed a common way to name destinations and move data between them.</p>
<p>The Internet Protocol provided that common language. An IP address became the routing label that helps network equipment forward a packet towards the right network and device.</p>
<h2>IPv4 connected a growing internet</h2>
<p>IPv4 became the standard in the early 1980s. It uses 32-bit addresses, usually written as four decimal groups, such as 203.0.113.10.</p>
<p>About 4.3 billion possible addresses seemed generous at first, but personal computers, smartphones, home routers, and connected equipment made the supply limited.</p>
<h2>NAT and the move to IPv6</h2>
<p>Private address ranges and network address translation (NAT) let many devices share one public IPv4 address. This conserves addresses but can complicate direct incoming connections.</p>
<p>IPv6 uses 128-bit addresses and offers a vastly larger space. IPv4 and IPv6 commonly operate together while the transition continues.</p>
<h2>Frequently asked questions</h2>
<div class="content-faq"><div class="content-faq__item"><h3>Who assigns IP addresses?</h3><p>Providers usually assign public addresses, while routers and network administrators assign private addresses inside local networks.</p></div><div class="content-faq__item"><h3>Can an IP address change?</h3><p>Yes. Consumer connections often use dynamic public addresses that can change over time.</p></div></div>
