Google over IPv6 Google over IPv6At Google, we believe that IPv6 is essential to the continued health and openness of the Internet – and that by allowing all devices on a network to talk to each other directly, IPv6 will enable innovation and allow the Internet's continued growth.
In March 2008, we began offering Google search over IPv6 on IPv6-only websites like ipv6.google.com (IPv6 connection required), but other Google products were not generally available over IPv6.
That's why we created Google over IPv6. If you operate a network that supports IPv6, enabling Google over IPv6 lets you give users seamless access to most Google services over IPv6 simply by going to the same websites they usually use, such as www.google.com.
Google over IPv6 uses the IPv4 address of your DNS resolver to determine whether a network is IPv6-capable. If you enable Google over IPv6 for your resolver, IPv6 users of that resolver will receive AAAA records for IPv6-enabled Google services.
Normally, if a DNS resolver requests an IPv6 address for a Google web site,
it will not receive one…
…but a DNS resolver with Google over IPv6 will receive an IPv6 address,
and its users will be able to connect to Google web sites using IPv6.
To qualify for Google over IPv6, your network must have good IPv6 connectivity to Google. Low-latency, redundant paths using direct peering or reliable transit are required. Your network must provide and support production-quality IPv6 networking and provide access to a substantial number of IPv6 users. Additionally, because IPv6 problems with users' connections can cause users to become unable to access Google if Google over IPv6 is enabled, we expect you to troubleshoot any IPv6 connection problems that arise in your or your users' networks.
If your network meets these requirements and you'd like to receive Google over IPv6, please let us know at google-ipv6@google.com.
