Private DNS 
To get information from a website, your phone first asks where 
the website is. Private DNS is a way to help secure these 
questions and answers. 
By default, your phone uses Private DNS with all networks that 
can use Private DNS. We recommend keeping Private DNS 
turned on.   
Open Settings and touch Network & Internet > Private DNS to 
turn Private DNS on or off, or change its settings.
