Those IPs appear to be used by to Google cache servers at the QIX. It's common for CDNs to utilize provider space and not maintain their own layer-3.

Seems like an odd waste of resources; what if Google, Akamai, Netflix, and anyone else who wanted caches wanted IPs in that block? The IX would be out of address space pretty quickly, forcing a majority of users to re-number because of a small number of other users. -Dave On Thu, Mar 12, 2015 at 1:07 PM, Steven Schecter <schecter@gmail.com> wrote:

that sounds like a recipe for disaster with respect to latency and jitter and control of destination of the user request, eh? Have you tried using 6to4 gateways?

In this case they being Google and their being Google's IP space (but you can replace Google w/ any provider using caching servers). When I was using Comcast 6to4 gateway, the latency wasn't too bad (I'm a Comcast customer). If the anycast is being broadcast from a regional datacenter and your ISP has good connectivity, the latency shouldn't be bad (in the QIX case above, the latency shouldn't be any worse than QIX's IPs unless someone started advertising the same anycast subnet w/ a lower cost). ----------------------------------------------------------------------------------------------- -ITG (ITechGeek) ITG@ITechGeek.Com https://itg.nu/ GPG Keys: https://itg.nu/contact/gpg-key Preferred GPG Key: Fingerprint: AB46B7E363DA7E04ABFA57852AA9910A DCB1191A Google Voice: +1-703-493-0128 / Twitter: ITechGeek / Facebook: http://fb.me/Jbwa.Net

this has the same uncertainty problems with other folk I imagine.

there are a lot of ifs there... and failover is where the problems arise :(
one of the legacy uses of an IX was to place “content” near the eyeballs. For the adventurous, this meant placing NTP chimers, DNS & route servers, and even content directly on the switch mesh. Akamai might have been the first to pull back from that and move its services behind an Akamai router that was on the switch mesh. These days, most folks use BGP “condoms” to protect themselves. manning bmanning@karoshi.com PO Box 12317 Marina del Rey, CA 90295 310.322.8102 On 14March2015Saturday, at 12:55, Dave Temkin <dave@temk.in> wrote:

Hi Jason, This is not commonplace. That prefix is from a specially designated IXP micro allocation block. See http://bit.ly/1OEcHde for detail. The use of these specially designated blocks is for IXPs only. We (Akamai) don't have equipment numbered into this type of address space nor do we have any evidence that we have in the past. We certainly won't in the future. If someone knows of anything that we missed, contact me directly and we'll arrange to renumber. Hope that helps.
