Some time ago Google implemented auto complete feature inside search input field. But I just noticed, it works as well if you start typing full domain name with protocol. Results are, I suppose, most typed things in search field. No matter typing url into the Google always fascinated me, the sites that show up fascinate me even more.
This is what shows up on google.com as first auto complete results if you start typing “http:”:
and this if you start typing "https:":
