Hi,

I'm currently testing ipv6 only networks and services to find things that ne=
eds fixing, and when trying to install Debian Trixie using a IPv6 only netwo=
rk with SLAAC configuration the installation fails to detect a network. If i=
 exit to a shell i can ping both the default gateway as well as the two DNS s=
ervers that are running in the local /64 network. If I manually set the DNS s=
ervers in resolve.conf then I can ping and resolve things on the internet bu=
t the installer still does not detect internet and can only install the base=
 OS.

So it looks to me like the installer fails to set the DNS correctly when usi=
ng a pure SLAAC network. (Once installed the system has no issue running on a=
 SLAAC only network and the dns gets configured as expected).

Anyone here that can update the installer to support DNS over SLAAC? This is=
 the netinstall image by the way.

Best regards,

Thomas=20
