Thanks for the information. I am still working on changing the system IPv6 default. I have currently relented to specifying every individual IP address that needs to listen for RADIUS across the set of systems running Radiator (both v4 and v6), and I will just live with the binding errors when Radiator starts. The reason is that the Radiator config is managed in a single file that is pushed to multiple systems to ensure consistency of the config. Works great, until trying to support IPv6. Living with the startup errors makes me cringe, but I don't expect success in getting the default changed. At least that gets me CIDR support for IPv4.
I still need CIDR support for IPv6. Many (and soon, the majority) of the clients are going to be IPv6, so most of them will require individual entries (hundreds of them), without CIDR support. From a customer perspective, I think CIDR notation for IPv6 is critical. That is the industry standard way of notating IPv6. Is there any plan for IPv6 CIDR support in the future? If so, what timeframe? Thanks for your help. -Jason On Jun 28, 2013, at 9:38 AM, Heikki Vatiainen <h...@open.com.au> wrote: > On 06/28/2013 03:17 PM, Mueller, Jason C wrote: > >> I am still using ipv6:::, since I have not yet convinced system >> administrators to change the bindv6only attribute to 1. >> >> The example above (which a couple of others also suggested) works for a >> single address (i.e., ipv6:::ffff:128.255.90.90).
