Abstract:
A method for reserving a predetermined Internet Protocol (IP) address in a remote access server (RAS) of a network server, the method comprising the steps:providing a finite series of IP addresses having a first address and a last address in sequence; specifying a first fixed address that is intermediate to the first and last addresses, where a portion of the series of IP addresses from the first fixed address to the last address comprises a fixed IP address pool and a remaining portion of the series of IP addresses comprises a dynamic IP address pool, and where the fixed IP address pool includes the predetermined IP address; permitting a remote client that connects to the network server to request an IP address value in an IP address request to the RAS; receiving an IP address request from a remote client; searching only the dynamic IP address pool for an available IP address if the IP address value in the IP address request from the remote client is a predetermined value and, if an available IP address is found, assigning it to the remote client; and searching only the fixed IP address pool for the IP address value in the IP address request from the remote client when the IP address value in the IP address request is not the predetermined value and, if the IP address value in the IP address request is found and is available, assigning the predetermined IP address to the remote client.
