RE: Google Over IPV6
AFAIK you have to have native peering with them to be part of the pilot. At least, you did when we signed up. They may have relaxed that since. According to a Google IPv6 talk I attended yesterday, they don't intend to relax that rule. Tunneling ipv6 connectivity over ipv4 is trash quality engineering and to be honest, its not a credible substitute for adequate ipv6 infrastructure. facetious Tunneling ipv4 over mpls is trash quality engineering and it's not a credible substitute for adequate ipv4 infrastructure. /facetious Everything is a tunnel... Indeed, but the differentiator here is that the transport for the tunnel in question also provides connectivity to the destination; i.e. - you can get to Google over IPv4. You do not (or, atleast I do not :)) have the option of connecting to Google over MPLS, Ethernet, etc. /TJ

Most companies, though, are completely reliant on their vendors, which means buying a new version, testing, deployment, etc. -- assuming the vendor is still in business, hasn't discontinued the product, has even bothered to try implementing IPv6 yet (most haven't), etc. That may also involve an upgrade of the OS that the app runs on, purchasing new hardware to handle the bloat in newer OSes, etc. You may also need to upgrade your LAN hardware to models that support IPv6 forwarding in hardware, more RAM for routers to run IPv6 code (if it's even available), new VPN boxes, etc. Now, if you keep up with your upgrades every year, and stop using products when the vendors stop supporting them or go out of business, most of this should already be built into your budgets -- but not many execs see value in that.

For you to be doing this, you must have IPv6 connectivity and your IPv6 network must meet Google's fairly stringent requirements. Regards, K. I see cname www.l.google.com and only IPv4 addresses :( Well talk to your ISP and have them turn up IPv6. :-) If they can't do native all the way to you, have them bring up a local tunnel server so they are in a position to diagnose problems with the entire tunnel path.

Re: Google Over IPV6
* Robert D. Scott: When I posted my original note, I was not really looking for end user feedback, but rather is anyone peering V6 with them on either a public fabric or private peer. Any idea if they have native V6 transit, or are tunneling, and to where. Google seems to aim at Tier 1 status for IPv6. No transit, no tunneling.

Map tiles over IPv6 was turned on last week during the Google IPv6 Implementers meeting, and other stuff is IPv6 as well.

Any idea if they have native V6 transit, or are tunneling, and to where. Google seems to aim at Tier 1 status for IPv6. No transit, no tunneling. From their web page at http://www.google.com/intl/en/ipv6/: To qualify for Google over IPv6, your network must have good IPv6 connectivity to Google. Multiple direct interconnections are preferred, but a direct peering with multiple backup routes through transit or multiple reliable transit connections may be acceptable. 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. So you need multiple IPv6 connections or one IPv6 connection with transit IPv6 support to get it. A university with a direct peering with Google and and Internet2 transit to google would probably qualify. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
