Not sure exactly what that instant answer is doing, but I can answer the bigger question.
Your IP is never used to geolocate/personalize regular results. Never. You can manually change your location in the settings for those.

Instant answers (that gray box at the top of results) do sometimes use your IP, e.g. weather. GeoIP is always done on DDG servers with a local database, so nobody else gets your IP--just your approximate location, in those few cases.
