Abstract
A method is shown for splitting a static pool of Internet Protocol (IP) addresses in a Remote Access Server (RAS) of a network server device into a dynamically assignable pool and a fixed assignment pool. The IP addresses of the dynamically assignable pool are available to any remote client connecting to the network server. The IP fixed assignment pool contains IP addresses that have a predetermined assignment to specific remote clients. When a remote client connects to the network server, it requests assignment of an IP address from the RAS. If the remote client does not specify an IP address in its IP address request, then an IP address from the dynamically assignable pool is assigned to the remote client for the duration of its connection to the network server. If the remote client does specify an IP address in its IP address request, then the fixed assignment pool is searched for the requested IP address and the address is assigned to the remote client. The IP addresses of the fixed assignment pool are never assigned to a remote client that does not request a specific IP address.
