I'm not sure we'd want to carry the way metadata works forward now that we have had some time to think about this. We already have DHCP6 and NDP. Just use one of those, and set the host's name to a nonce that it can use to lookup the endpoint for instance differentiation via DNS SRV records. So if you were told you are d02a684d-56ea-44bc-9eba-18d997b1d32d.region.cloud.com Then you look that up as a SRV record on your configured DNS resolver, and connect to the host name returned and do something like GET /d02a684d-56ea-44bc-9eba-18d997b1d32d And viola, metadata returns without any special link local thing, and it works like any other dual stack application on the planet. __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: [email protected]?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
