How to integrate whois in my web application
Posted by File-Big@reddit | learnprogramming | View on Reddit | 2 comments
I want to create a web application similar to HackerTarget's Autonomous System Lookup. The thing is that I don't want to use any external API's for the lookup, instead I want to use whois and I don't know how to integrate that, any help would be greatly appreciated.
I have created a Python script using Flask, installed whois. I want a really minimalist application with a search bar where I can insert several IP Addresses and get their ASN.

I assume you mean you installed the
whoiscommand-line tool? If so, you can run it from your Python program and capture its output using the built-insubprocessmodule.There are also Python modules that will act as a client for the WHOIS protocol directly, without requiring a separate subprocess, e.g. python-whois.
Or, if you want, you could implement the protocol yourself using sockets by reading and following the RFC 3912 specification.

Yeah, WHOIS is pretty much the simplest protocol out there. Connect to port 43, send domain name followed by \n and then read the results.
