The fastest browser-based IPv6 connectivity test available. Six comprehensive tests complete in under 15 seconds by running all checks in parallel. The moment you open the page, it simultaneously tests IPv4-only endpoints, IPv6-only endpoints, dual-stack compatibility, latency, and protocol preferences. Everything runs client-side with zero backend latency. No server round-trips, no queuing, no waiting. Written in vanilla JavaScript with no framework overhead
I started building this after hearing that test-ipv6.com might shut down. Instead of hosting another mirror, I decided to design a new site with a modern UI and similar functionality. It's fast – sometimes even faster than the original. Would love feedback from the community.
By the time I published it, I was very glad to hear that test-ipv6.com will continue. But since I'd already done the work, I chose to publish it anyway as an alternative – just another option for the community.
