Python Network Programming

How to do it...

As you have installed ldns, now you may check out the Dyn's dns_lg source code from its source code repository:

git clone [e-mail]:dyninc/dns_lg.git
    
cd dns_lg/
  

Now, you may run the application simply by executing api.py. Running it produces the following output:

$ python api.py
* Running on http://0.0.0.0:8185/ (Press CTRL+C to quit)

Now open another console window to run a curl:

curl http://0.0.0.0:8185/cnn.com/

This will output a line to the preceding api.py console:

127.0.0.1 - - [15/Jul/2017 23:33:40] "GET /cnn.com/ HTTP/1.1" 200 -
  

The curl command produces the following output with the detailed DNS information from the looking glass implementation:

$ curl http://0.0.0.0:8185/cnn.com/
