The response time from a client on a network is measured and a destination address is selected based on the measured response time. The client requests an address from the network. The network may be a local network or a wide area network such as the Internet. The response time of the client is measured to determine the optimum speed at which the client may operate. The measured response time is communicated to the server, where a destination address is selected based on the requested address and the measured response time. The client may then be connected to the destination address.
