Test your IPv6 connection online and check whether your device or network has working IPv6 connectivity.
Check whether your current connection supports IPv6.
Use this free IPv6 test to check whether your current internet connection supports IPv6. The tool attempts to connect to an IPv6-only service and detects whether IPv6 connectivity is available.
IPv6 is the newer Internet Protocol designed to provide a much larger address space than IPv4. Many modern internet connections support both IPv4 and IPv6.
IPv6 stands for Internet Protocol version 6. It was created to provide a much larger number of internet addresses than IPv4. IPv6 addresses use hexadecimal characters and are separated by colons.
An IPv6 test can help you troubleshoot connectivity problems and determine whether your internet service provider, router, or network currently provides IPv6 access.
IPv4 uses 32-bit addresses, while IPv6 uses 128-bit addresses. IPv6 provides a significantly larger address space and was designed to support the continued growth of internet-connected devices.
If this tool reports that IPv6 is not available, your current network may not have IPv6 connectivity enabled. This does not necessarily mean that your internet connection is not working. You may still be connected successfully through IPv4.
IPv6 availability depends on your internet service provider, router, operating system, and network configuration. If your ISP supports IPv6, check your router's network settings or contact your ISP for configuration information.
Yes. You can use this IPv6 connectivity test online for free without installing software.
An IPv6 test checks whether your current internet connection can communicate over IPv6 and can display your public IPv6 address when available.
Run this IPv6 test. If the test successfully connects to the IPv6 endpoint and detects an IPv6 address, your connection has working IPv6 connectivity.
The test can fail when your ISP, router, device, or current network does not provide IPv6 connectivity. Some networks support IPv4 only.
IPv6 is not automatically faster than IPv4. Performance depends on your network, ISP, routing, server, and other connection factors.
An IPv6 address uses hexadecimal characters separated by colons, for example 2001:db8::1. The address shown by this tool will be your detected public IPv6 address when available.
Yes. Many modern networks use dual-stack connectivity, allowing devices to communicate using both IPv4 and IPv6.
Yes. This online IPv6 connectivity test is free to use.
Some mobile networks support IPv6, while others may use IPv4, IPv6, or transition technologies. The result depends on your carrier and current network configuration.
