A comment on Iodine – tunneling IP over DNS. Parent comment

Nope. Public paywalled hotspots often have ip whitelists while you didn't pay. So they'll let everything trough that goes to THEIR dns. Openvpn on 53 won't help you here. Iodine will.

I don't know why they serve full dns to unpaid users. Maybe to avoid os dns cache issues.

I've used iodine a few times in the past while traveling. Works like a charm.

I see. You can use Iodine to tunnel through any arbitrary DNS server, even ones not under your control. I didn't appreciate that when I posted the above comment. Very neat.

They serve full DNS because then it's a single configuration to bother with - regular DNS. Until tools like this are factored for, there's no reason to do anything stateful with the DNS response. It'd just be extra work.
