import socket

# Get the fully qualified domain name

fqdn = socket.getfqdn()

print("Fully qualified domain name of this computer is:");

print(fqdn);

# Get FQN for example.net

hostName = "www.example.net";

fqdn = socket.getfqdn(hostName);

print("Fully qualified domain name of %s is:"%hostName);

print(fqdn);
