Prerequisites

Running

To run this sample execute the sample/basic/basic_reverse_name_server_example.py script as follows:

python sample/basic/basic_reverse_name_server_example.py

The output should appear similar to the following:

{
    "response": {
        "name_server": {
            "hostname": "domaintools.net",
            "primary": 159,
            "secondary": 0,
            "total": 159
        },
        "primary_domains": [
            "aveneparis.com",
            "aveneskin.com",
            "aveneskinshop.com",
            "avenetherapy.com",
            "blank-nameserver.com",
            "bulk-check.com",
            ...
        ],
        "secondary_domains": []
    }
}

The received results are displayed.

Details

The majority of the sample code is shown below:

# Create the client
with DxlClient(config) as client:
    # Connect to the fabric
    client.connect()

    logger.info("Connected to DXL fabric.")

    request_topic = "/opendxl-domaintools/service/domaintools/reverse_name_server"
    req = Request(request_topic)
    MessageUtils.dict_to_json_payload(req, {"query": "domaintools.net"})
    res = client.sync_request(req, timeout=30)
    if res.message_type != Message.MESSAGE_TYPE_ERROR:
        res_dict = MessageUtils.json_payload_to_dict(res)
        print(MessageUtils.dict_to_json(res_dict, pretty_print=True))
    else:
        print("Error invoking service with topic '{}': {} ({})".format(
            request_topic, res.error_message, res.error_code))

After connecting to the DXL fabric, a request message is created with a topic that targets the "reverse name server" method of the DomainTools API DXL service.

The next step is to set the payload of the request message. The contents of the payload include the query parameter to report on.

From the DomainTools Reverse Name Server Documentation:

"The Reverse Name Server API provides a list of domain names that share the same primary or secondary name server."

The final step is to perform a synchronous request via the DXL fabric. If the response message is not an error its contents are formatted and displayed.
