This test reaches a service that exists only on IPv6. A response means your provider delivers native IPv6; no response means IPv4 remains the only path your connection has to the internet.
How it works
- 1Open the page and wait for the IPv6-only connection attempt.
- 2If an address appears, copy it to compare against your IPv4 address.
- 3If nothing appears, read the common causes below before contacting your provider.
Why is my IPv6 not detected?
The usual causes are carrier-grade NAT without IPv6, an older router with IPv6 disabled, a firewall blocking ICMPv6, or a corporate network advertising IPv4 only. Try another device and disable the VPN before drawing conclusions.
Do I need IPv6 today?
The internet works without it, but IPv6 improves access to services that already run on it exclusively and often reduces latency on modern mobile networks.
