question about IPv6-DNS-nameserver link-local (with Interface-name)

[Thomas Schäfer]

Hi,

In my test environment some soho/mobile routers propagate 
IPv6-link-local-adresses to the client(DNS).

In general there is no problem.

Opensuse/NetworkManager writes to /etc/resolv.conf

nameserver fe80::d27a:b5ff:fe7b:e152%wlan0

(Win7, win8, looks similar with its interface-ID)

Ubuntu configures dnsmasq to use this address.

So far so good.
But not all applications accept this DNS-Resolver.

"host" and "dig" make problems.

I described the Situation here in more details.

https://bugzilla.novell.com/show_bug.cgi?id=885053


But I am not sure, where is the bug?
Is it ok, to assign link-local-addresses in /etc/resolv.conf?
or
Are "host", "dig" and maybe other apps buggy?
(confused by IP-addresses with interface extension)
If you try to reproduce my problem - switch off ipv4.

Regards,

Thomas
