[IronPython] socket.getfqdn problem on 2.6.1 RC1.

[Carlos Alberto Costa Beppler]

The problem is that the HTTPServer from standard lib is doing the call
on line 109-110 of the file BaseHTTPServer.py on method server_bind.
See the code bellow.

class HTTPServer(SocketServer.TCPServer):

    allow_reuse_address = 1    # Seems to make sense in testing environment

    def server_bind(self):
        """Override server_bind to store the server name."""
        SocketServer.TCPServer.server_bind(self)
        host, port = self.socket.getsockname()[:2]
        self.server_name = socket.getfqdn(host)
        self.server_port = port

The host variable gets '0.0.0.0' and when the call to socket.getfqdn
is made the exception is thrown.
