| 1. A method of selecting a host for a client in a client-server network,
the method comprising:
receiving a request to identify the host for the client at an authoritative server;
instructing each of a plurality of servers to respond to the received request at a time that is related to the latency between
each of the plurality of servers and the authoritative server, said latency being determined after said request;
sending a plurality of responses from the plurality of servers and the authoritative server to a local server after receiving
the instruction, each response having an address representative of a respective host, said plurality of responses are sent
to the local server at substantially the same time after a one direction latency is calculated between the authoritative server
and each of the plurality of servers;
determining at least one latency involving data transmission between each of the plurality of servers and the local server
and the authoritative server and the local server, the at least one latency being determined after the request; and
selecting a first arriving respective host address from a first arriving response of the plurality of responses.
