   We all know about the public DNS services offered by Google (8.8.8.8,   
   8.8.4.4) and Cloudflare (1.1.1.1, 1.0.0.1); did you know these   
   addresses have names as well? And of course there are IPv6 addresses to   
   go with the IPv4 ones.   
      
   Try this command to find out all the related Google DNS services:   
      
       host -a dns.google.   
      
   (Yup, that’s “dns.google.”, no “.com” or anything else on the end.)   
   That’s quite a breathtaking list of entries.   
      
   For Cloudflare, try   
      
       host one.one.one.one.   
      
   Note that the “-a” option (“tell me everything”) doesn’t work with   
   Cloudflare; quite a few online services are now imposing restrictions   
   on these “all info” lookups, but clearly not Google, at least not on   
   this domain: obviously they want it to remain easy for people to   
   discover the services they’re offering.
