Three years ago I wondered when wordpress.com would begin to support IPv6. The irony of hosting a blog that talks a lot about IPv6 on an IPv4-only platform is not lost on me 😦
This is not an OS issue, a load balancer issue, a PHP language issue, or even a WordPress software issue. I’ve seen WP software running full dual-stack, no problems. Five years ago. I’ve done it myself, I just don’t want to run WP myself anymore.
For whatever reason, WordPress.com has not decided to commit to the future. yet.
