  Method for allowing a client and host to affect the resolution address from a name server.

Disclosed is a method for enhancing the Directory Name Server (DNS) such that a client requesting an address of a host can affect the resolution of that address to a specific set of addresses defined for that host.

The proposed idea is to include in the DNS name service request a token that indicates to the name server that it should resolve the host name request from a list of addresses that have a host name and token association at the name server. The process of registering a name with the name server would allow for creating an association between the host name that is being registered and a token. If the token host name pair does not exist on the name server then the name server would resolve the name using existing algorithms.

The proposed idea allows the client and the server whose address is being requested to coordinate on the meaning of the token without any involvement from the name server as the token has no meaning to the name server. This allows the client and server to use the token to say provide for say an initial quality of service based on client connection type. Using the connection type allows the client to be directed to an address that matches the connection type of the client. Thus if the connection type is dial up the name may resolve to a slower server and a connection type of broadband may resolve to a faster server. The token could be used to all...
