Also super useful to tunnel data across in open wifi networks. Using a DNS tunnel there, you end up in a legal gray area where you haven’t clicked the “I Agree” button on the wifi capture portal, but you’re still using their network.
Boingo got smart to this technique unfortunately. I was at one time able to connect via their networks without paying thanks to DNS tunneling. Now if you’re an unauthorized (haven’t paid yet) MAC address, all DNS requests return private IP addresses, and external requests are blocked.
