[dns-operations] DNS over Wikipedia

Wikipedia keeps track of official URLs for popular websites. With DNS 
over Wikipedia installed, domains ending with .idk are redirected by 
searching Wikipedia and extracting the relevant URL from the infobox.


1. Type scihub.idk/ in browser address bar
2. Observe redirect to https://sci-hub.tw (at the time of writing)


My question is about their implementation.
Does it mean any domain ending with .idk went to an interface, this 
interface queried the domain part before .idk from wikipedia, then 
returned a URL redirection to some other website?

I thought querying from wikipedia's API directly (or google API) is even 
more efficient than this way.
