You can test DNS resolution by doing this:

import socket
# Check to make sure domain is legal and that I can resolve it to IP addr
except socket.gaierror:
     print "Internet connection or DNS error"

For the "connect to a specific website" portion you just have to wait until it 
times out to determine failure.
