Comment 37 for bug 258801

Hmm, I always suspected that my provider was the faulty link here, never thought that 10.11.12.13 where globally classed as faulty... (Hehe I really should have thought of that after looking more closely at the ip-address...)

As a side note, vodafone-mobile-connect from https://forge.betavine.net/projects/vodafonemobilec/ could detect that these faulty DNS servers where issued and issued a bubble popup style warning about that the user might need to disconnect and reconnect to correct this.

If the bug cannot be fixed on it's own (the provider may be the one whos sending 10.11.12.13...), then Network Manager should both issue a formal warning as well as ask if the user wants to use the last known good DNS servers for that connection instead.
