www.tomshardware.com is an alias for g.sni.us-eu.fastly.net.

It would not be difficult for them to enable this: https://www.fastly.com/blog/ipv6-fastly (tl;dr: prepend "dualstack." to that alias)

Unfortunately, I cannot find a simple webmaster contact for them. If someone knows how to reach their IT people, please pass this along.

IPv6 at Fastly | Fastly

As Fastly CEO Artur Bergman has [said](https://www.fastly.com/blog/support-http2), “We will always insist that every component of the Fastly platform is fully integrated – we don't limit features to subsets of our network.” We take the time to fully integrate standardized protocols and technologies like [HTTP/2](https://www.fastly.com/blog/http2-now-general-availability) and IPv6 into our stack, and maintain the standards our customers have come to expect. Here’s our story of the evolution of IPv6 at Fastly — and how to implement it.
