Yiwen,

127.0.0.1 is the loopback address. The IP stack of a machine may use
this address to send packets to itself. What happens is that if you send
a packet to 127.0.0.1, the IP stack will at once see that it has received
the very same packet. And the packet will never be seen on the network.!

Well, having that as a server address is surely nothing special,
but most people will know the consequences...
