> To do that, DuckDuckGo gets its results from over four hundred sources. These include hundreds of vertical sources delivering niche Instant Answers, DuckDuckBot (our crawler) and crowd-sourced sites (like Wikipedia, stored in our answer indexes). We also of course have more traditional links in the search results, which we also source from multiple partners, though most commonly from Bing (and none from Google).
In other words, their own crawler and the other 400 sources are used for their Instant Answers and widgets while all "traditional links" (i.e. the search results) come from Bing.
Search for "what is my ip" and you will see Bing bot IP in the DDG snippets.
