Translator in the Cloud

In my previous blogs I’ve promised to explain how the IT team here at Juniper Networks implemented ‘translator in the cloud’ to create the ipv6.juniper.net URL allowing IPv6 clients to access any collateral on the Juniper Networks public site. This was a relatively easy 3 step process which I hope I can outline clearly today. Please don’t hesitate to leave a comment if any part needs to be clarified.

 

Today 0.4% of the top 1-million web sites are IPv6 reachable (Comcast IPv6 adoption monitor) a negligible amount for sure. Planned test-drives like the World IPv6 day on June 8th will increase the momentum toward IPV6.

 

Having talked to many customers who host content the effort associated with making this same content available over IPv6 is considered prohibitive. The translator in the cloud concept has been developed to address this very problem, making content available over IPv6 without having to change much if anything at all in the IPv4 service delivery infrastructure.

 

Here is how it works.

 

Step 1: Find a location that has IPv6 and IPv4 connectivity.

Step 2: install a translator IPv6 to IPv4 there and configure it to point it to your web server.

Step 3: Add a AAAA record for your web server pointing to an IPv6 address of the translator.

 

The following diagram may help explain this a little better. When the IPv6 client makes a DNS request for www.example.com, an IPv4 only site, the DNS server responds with an IPv6 address directing the client to a translator in the cloud which completes the translation to IPv4 transparently to the end client. The translation happens in reverse for data going back to the client from this server.

In Juniper’s case, we pointed a AAAA record for ipv6.juniper.net to the translator. That translator was statically configured to translate that IPv6 address into the IPv4 address of our web server and the traffic was re-injected in the Internet.  It has been working successfully since January 2011.
