Isn't ddg Bing results?

Quite sure Qwant does, but DDG does appear to have their own unique results.

For your convenience:

Try "what is my ip" and you will see that DDG displays 207.46.13.131 in the cached snippets, which is Microsoft Bingbot and also the same IP that Bing shows in their cached snippets.

DDG has their own crawler, but they augment results using Yandex and perhaps Bing too.

I remember reading that it uses only Bing for web results and their crawler for Wikipedia only.

I know they (at least used to) use some results from Yandex
