Multi-DoH Server

Warning: This code is highly experimental and I don't recommend running it in production.

The SkyDroid App uses this server to efficiently query a lot of domain names at once in a single request.

It is part of my submission to the ‘Own The Internet’ Hackathon

This server requires a HSD Node running locally with ./bin/hsd --rs-port 53

Enabling Unbound support is recommended.

This server listens on port 8053 and accepts HTTP connections. HTTPS can be enabled using a reverse proxy like Nginx.

Limitations

Example

POST to /multi-dns-query

{
    "type": 16,
    "names": [
        "example.com",
        "redsolver",
        "papagei"
    ]
}

Response

{
    "type": 16,
    "names": {
        "example.com": [],
        "redsolver": [
            "TXT Record 1",
            "TXT Record 2"
        ],
        "papagei": [
            "something something"
        ]
    }
}

How to deploy (if you really want to)

  1. Get the Dart SDK
  2. dart2native bin/multi_doh_server.dart to produce a binary
  3. Something like scp bin/multi_doh_server.exe root@YOUR_SERVER_IP:/root/multi_doh_server/multi_doh_server.exe to copy the binary to your server
  4. Run the binary
