This reminded me of a TCP-over-DNS hack[1].
You could use airport wifi access points protected by captive portal to browse internet without paying by sending traffic through DNS requests.

- niij 9y agoAs the link mentions, that software is outdated and Iodine [0] is a recommended replacement. I setup an Iodine server when doing some traveling and only had to use it one time, and it was painfully slow Not sure why it is slow, perhaps DNS packets must be smaller than a normal TCP packet? It was still pretty cool that it worked, but I wouldn't want to use it regularly. [0]: https://code.kryo.se/iodine/ https://code.kryo.se/iodine/
