@Delib #DuckDuckGo does not pro-actively send IP info to MS w/the query according to the privacy policy (which is hard to trust considering #DDG has been caught violating it multiple times). But if you trust the privacy policy, MS still sees your IP when you connect since MS hosts DDG. And MS also sees your query which DDG proxies to Bing. So MS can work out for itself IP-query pairings.
