scapy - dns sniffer

How to parse dns request and response ? Scapy is a powerful tool, and it can help us for dns detail.

#!/usr/bin/env python

"""
execute demo py with root privilege, and finish double dns query as follow.

    $ nslookup search.yahoo.com
    $ nslookup github.com

dns sniffer will parse dns requests and responses automatically.
