An IPv6 No Network Access error can occur on any Mac, PC, or mobile device, frustrating attempts to connect to a network. In this guide, we provide answers and instructions to get an IPv6 connection working again.

When a device connects to the Internet, it obtains one or more addresses on the network. Often, a device will obtain both an IPv4 address and an IPv6 address. IPv6 is a newer networking standard, intended to allow for a larger network of connected devices than the older, more widely used IPv4 protocol.

When configured correctly, most devices will work fine when connected to a network using at least one of these two protocols. But sometimes a device will connect and receive an IPv4 address and not an IPv6 address. For example, in Windows, when you look at the network connection details, your device may show a connection to an IPv4 network, but say No Internet access next to IPv6 connectivity.

There are several reasons why this error occurs. Usually, the cause is revealed by the precise troubleshooting step that fixes the problem.
