The title is misleading. It not going to make the web faster for everyone. Content hosted on CDN's that don't support the proposed DNS extension (http://tools.ietf.org/html/draft-vandergaast-edns-client-ip-01 http://tools.ietf.org/html/draft-vandergaast-edns-client-ip-...) ie Akamai, is probably going to be slower (higher latency.)
In fact, worst case is that you will be mapped to a server that is not allowed to serve your ip. CDN's get a lot of free traffic by helping isp's with peering imbalances. But this free traffic is restricted to specific ip blocks.
- davidu 15y agoThis option isn't enabled for Akamai. There is no way it can make Akamai slower. Title isn't misleading, but your comment is.
- sirn 15y agoI thought the parent is trying to say accessing content via Akamai will be slower when using Google Public DNS/OpenDNS because they don't support the purposed DNS extension thus the request is routed to a non-local server instead of local one? (Akamai is my main reason of not using OpenDNS to this date, otherwise I would make a switch for long)
- davidu 15y agoAhh, this is possible. Not as likely in the US, but possible. We're working on it. At least it's fixed for Youtube, all Google properties, a bunch of other CDNs now. But yeah, some big guys still remain! We'll get 'em.
- amalcon 15y agoMore importantly, it has no effect on the vast majority of users who are not using Google DNS or OpenDNS. This is a workaround for a specific problem with public DNS servers, and while it's not a bad one, we shouldn't pretend it's going to help everyone.
