Sometimes they require 3rd party stuff, hotlinked images, js on frontpage, etc. I was on a ferry ship with paid sattelite wifi internet once and they only faked DNS responses for gstatic.com, google, etc. But they allowed my domain (DNS queries to it) and stripe.com (because that's how you paid) -- so they only faked responses for a small set of popular domains. IP access to the internet was, apart from stripe, blocked. And because stripe uses FastlyCDN, they allowed all of fastlycdn network ranges (not useful for iodine), so I could browse reddit (they also use fastly) using stripe's CDN (only html, without i.redd.it image hosting, that's elsewhere). AFAIR Fastly doesn't have a free plan, so I couldn't tunnel at higher speeds (via HTTP) but only via DNS. But yeah, sometimes they just outright respond to any query with their IP and you are out of luck.
