It all started when was duckduckgo for Lucifer Netflix series and I ended up with 
Question #1: If lucifer and hell are not in my /etc/hosts, why ping says PING lucifer.STUDIO ?
Question #2: Are lucifer and hell Brand TLDs ? How can I search for Brand TLDs ?
ping lucifer
and ping hell
and the response says it is on the internet but is my local subdomain. What?
Code:
[@machine ~]$ hostname
machine.STUDIO
[@machine ~]$ grep -Ei "lucifer|hell" /etc/hosts
[@machine ~]$ cat /etc/resolv.conf
