 DNS-based pluggable transport.

 Encode data in recursive DNS queries and responses. Your local recursive
 resolver sends your packets to the right place. A DNS bridge would be an
 authoritative name server for a particular domain; users would configure a
 domain rather than an IP address in their Bridge lines. Tools already
 exist to do DNS tunneling, for example ​iodine and ​dnscat. Probably
 requires a reliability layer and periodic polling by the client.

 Provides a way for users behind restrictive firewalls to connect to Tor at
 the expense of speed.
