After installing a new router, I discovered that Charter is now providing IPv4 and IPv6 addresses to my router.

Been testing it a bit, and typically find that IPv6 provides better response time on pings and better throughput speeds, especially the more distant the source.

But it appears that Microsoft.com is yet to implement IPv6, as no IPv6 addresses are returned from DNS. The same is true for other "technology leaders", including Dell, HP, and IBM.

C:\Users\MtnMan>nslookup

IPV6 frontend isn't really a concern at the moment, the VAST majority of people will be using IPV4 anyway, and no one is really coming from an IPV6 only connection.

Almost all the companies you've mentioned do IPV6 in the data center, where the benefits are far more tangible.

You are at the mercy of Internet weather and traffic. Your deduction of IPv6 being faster isn't because of IPv6 itself, but more likely just less traffic/usage at whatever is processing your packet.

Regardless, nslookup is just the beginning of how Microsoft uses IPv6. Not everything Microsoft uses lives at the Microsoft domain. An example is their cdns and Azure. Yup. Apple uses Azure I know, but it's true.

What does test-ipv6.com show you, when you visit. I wonder if you have your IPv6-capable nameservers all in a row.
