IP Setup and Network Address Translation
Numerous factors influence the choice of served address. It is difficult to specify the address that will be served to a particular client in all circumstances. However, when the address server has been configured, and the clients involved have no prior address serving interactions, the Netopia R910 will generally serve the first unused address from the first address pool with an available address. The Netopia R910 starts from the pool on the first row and continues to the pool on the last row of this screen
