This is an experimental implementation of Neubot CDN test (see Neubot's specification for more info).

CODE STRUCTURE:

1.main.py: main program 2 nested for cycle(for all dns server->for all hostname): -resolve name -reverselookup (find the CNAME) -traceroute -whois

2.gethost.py: (e.g. gethost.py www.google.it 8.8.8.8) given an address(string) as argument resolves the name and a server dns as second arg.

3.reverse_lookup.py: (e.g. reverse_lookup.py 8.8.8.8) given an address(dot form) as argument retrieves the cname

NB: Still buggy. Tested only on linux. TODO: catch exception for example when the server does not answer or for example answer with an IPv6
