Abstract: A system for effectively reducing address resolution of a packet on a network by representing multiple addresses on a node of the network by a single maskaddress. An aggregation utility is utilized to aggregate the multiple addresses from an address space (i.e., a number of addresses having a common initial bits) of sequential addresses. A pre-selected aggregation percent, representing the percentage of actual addresses from the space which is present on the node, is utilized in the evaluation of the maskaddress. The maskaddress comprises of two variables. The first variable represents the size of the space and the common initial bits. The second variable provides information on the number of relevant bits to include in the maskaddress and the length of the space to point out the actual addresses, which are present in the space. A negative address utility is utilized to indicate which addresses from within the address pace are not hosted on the node.

Abstract: The present invention is a system, method, and computer readable medium for saving and reusing recently acquired Internet addresses. When a client computer receives an Internet address for a particular computer name, the computer name and its corresponding Internet address are saved in a client memory area. Before sending a request to a name server, the client memory is checked to determine if the desired computer name and corresponding Internet address are stored in the client memory. If so, the stored Internet address is used to access the desired machine. If the desired computer name and corresponding Internet address are not stored in the client memory, the requested computer name is sent to the name server for conversion. The name server passes the Internet address back to the client, where it is used to access the machine, and is also stored in the client memory for future use.
