Implementation of a caching DNS Server

General description

This is an implementation of a UDP caching DNS server written in Python3.
All written operations are correspond to RFC 1035

Requirements

  • Python 3.*
  • IPy

Usage

To run a server use the next command:

  1. $ python3 dns.py [-h] [-p P] [-f F]

List of arguments:

Argument Description
-h, —help Show this help message and exit
-p P Port for running a server
-f F Address of a forwarder written in format IP:Port. Port can be omitted

For example, you run a server on 9090 port. Then you can make queries to it by typing the next command (get A records from google.com):

  1. dig +notcp @127.0.0.1 -p 9090 google.com A
