Whats a "dns trapper" ?

A "transparent" proxy that intercepts DNS requests and provides edited
results intended to improve your customer experience, typically
defined as returning A records for web servers full of advertisements
when you were expecting something else.

The unfortunate fact is that if you're using random networks, you'll
get increasingly random results, and there's no substitude for a tunnel
back to a known network.
