I have two systems here, my desktop, which uses wicked for network configuration and my notebook, which uses network manager. My DHCP server (pfsense) hands out 172.16.0.1 & 8.8.8.8 and RDNSS is used to provide an IPv6 DNS address. Wicked is configured to use 172.16.0.1 & 8.8.8.8, relying on RDNSS for the IPv6 DNS address. On my desktop, resolv.conf lists both IPv4 and IPv6 DNS addresses, but my notebook only gets the IPv4 addresses. It appears wicked accepts the RDNSS info, but network manager doesn't. In network manager, on both IPv4 and IPv6 tabs, Automatic is selected. Is there some other option for RDNSS? tnx jk

James, ISTR to remember exactly this situation - if I am not mistaken, networkmanager does not support RDNSS. See also your own bugreport #1113152 -- Per Jessen, Zürich (8.2°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland.

Yeah, I'd forgotten about that. That was with 15.0 and it's still broken in 15.2. RDNSS is part of the router advertisements, so it there's no excuse for not using it.

There's one other curious thing I've noticed. On my desktop system, where RDNSS does work, the DNS requests use IPv6 for a while and then IPv4, though I think mostly IPv6.
