Bizarre and Unusual Uses of DNS

  Official git repo for iodine dns tunnel

Iodine (https://github.com/yarrick/iodine) will do this. I did it with my home Internet connection as the server and found it very useful in a pinch.

Using DNS to exfiltrate arbitrary data thru firewalls that don’t log DNS requests is handy too.

Tangentially related: One can store SSH server host keys in DNS and tell the client to make use of them. This is an alternative to the client asking the user to confirm the server host key, which many people just blindly confirm.

I asked GitLab if they could make use of that, but it hasn't received much attention so far:

• dns-alt-svc

  3 70 3.3 Makefile

  Draft for listing Alt-Svc records in the DNS

Note that there are both HTTPS and SVCB record types.

Regardless of the standard being finalized there's already some support in the wild. To name a few prominent ones iOS, macOS, Cloudflare, Akamai, and NS1 all support both types.
