Why, if it is encrypted?

#13The iodine protocol allows bi-directional ipv4 traffic over DNS. https://github.com/yarrick/iodine
This is pretty good for bypassing captive portals on public Wi-Fi access points. Sometimes you can use it to get Internet for free without paying. These days most are more clever and will block everything other than the default gateway until you sign on.

#14Actually I turned DNS into a database ;)

#15"Like when one of the parties is under severe censorship."
What if the censor hijacks DNS queries. This is also done outside the realm of censorship, e.g., hotel wifi networks.

Four years ago I managed to use it on a plane to read mails over SSH in a terminal. It was so slow I had the impression to be in a spaceship to another planet...

:) to be fair SSH doesn't cope well on high latency, high packet loss connections.

mosh[0] helps a lot in these scenarios. It doesn't actually make your connection any faster, but it does make things feel a lot more responsive.
