Not really sure what to use for search now. DDG doesn't support IPv6 as I discovered last week while working on an #IPv6 only network. Neither does #Mojeek (and their language support is limited to ascii-only languages - even entering "français" it will ask "did you mean francais?" (same for umlauts) and Russian and Ukrainian aren't indexed at all).
Google and Bing are the only ones I know with IPv6 support.
We seem to be getting driven off the web, folks.
