IPv6 (Internet Protocol version 6) is the latest Internet protocol designed to replace IPv4, which is gradually running out of available addresses. With its 128-bit length, IPv6 provides an almost unlimited number of IP addresses while also improving connection speed, security, and support for IoT devices.
However, not all users know whether their network already supports IPv6. Below are 4 simple and quick ways to check IPv6 on your computer or online.
Method 1: Check Online

If the site displays an IPv6 address instead of IPv4, your network is prioritizing IPv6.
Benefits of using IPv6:
No shortage of IP addresses: supports billions of devices connected simultaneously.
Improved speed and performance: more efficient data routing compared to IPv4.
Enhanced security: built-in IPsec reduces the risk of attacks.
Future-ready: compatible with 5G, IoT, Smart Home, and other upcoming technologies.
Checking whether your Internet supports IPv6 is very simple and only takes a few steps. If your modem/router hasn’t enabled IPv6 yet, contact your Internet provider for activation support.
IPv6 is the inevitable trend, offering faster speeds, stronger security, and more stable connections for users.
