I remember 15 years or so; a friend and I figured out that DNS got through my friends cellular connection even though the data limit were reached.
We tested and set up a socks-over-dns-proxy back then and it worked! We loled and then never did anything more than that unfortunately (or it depends, we´d most likely be detected if we continued to use that, eh, solution).
- philsnow 4y agoAbout 15 years ago as well, a cruise ship I was on blocked most connections if you hadn't paid, but allowed DNS, so I tunneled some vpn over dns and it worked.
- teaearlgraycold 4y agoI want a comedy sketch for this where you’re explaining your traffic to a sysadmin. “I just really like looking up A records from dig”
- gloyoyo 4y agoSo true. Supposedly, worked in a couple cases, but they knew to accept the quote.

- hsbauauvhabzb 4y agoThis is really common in ‘airgapped networks’ so much that tools exist to create tunnels. I tested this on a job and upstream dns servers blocked me after about 1mb of traffic, it’s an abuse of a public service and a complete waste of resources (5-10x amplification) so something that’s completely understandable. I imagine 10 years ago, controls may not have been so good though. Edit: part of the rationale in some cases, I believe, is to facilitate captive portals for hotel wifi login etc.
