[python]DNS resolution webapp with flask

Very simple webapp, I still need to do some styling with CSS… this is a simple concept.
here’s an example:

The output will be:

Here are the jinja2 templates:

Here’s the code.

from flask import Flask, request, render_template
import socket

def host_processing(host):
    answer = ""
        answer = socket.gethostbyname(host)
    except Exception:
        # If not resolvable, dun care.

    if answer:
        return answer
        return host

app = Flask(__name__)

def main_form():
    return render_template('tool.html')

@app.route('/', methods=['POST'])
def post_form():
    answers = []
    hosts = request.form['text'].split(',')
    for host in hosts:
    return render_template('answers.html', answers=answers)

if __name__ == '__main__':

  1. If you want the output not to be a list, and want to separate them as commas use take out all for loop in the template, and insert {{ ‘,’.join(answers) }}

  2. To publish the flask to external for demonstration, do this render_template(debug=True,host=’′), else the webservice will only be accessible by localhost.
