The invention relates to an AAA (Authentication, Authorization, Accounting) server system (RADSS) for managing a pool (A) of logical addresses (IP 1 , . . . , IPN) and a method for updating status information within the AAA server system (RADSS). Said AAA server system (RADSS) comprises several AAA servers (RAD 1 , RAD 2 , RAD 3 ). Each of the AAA servers (RAD 1 , RAD 2 , RAD 3 ) are assigned one or more discrete partial amounts (A 1 , A 2 , A 3 ) of the address pool (A). Status information exchanged relating to address allocation affect the discrete partial amounts (A 1 , A 2 , A 3 ) of addresses. The invention has the advantage of a low-complexity and efficient message exchange between the AAA servers (RAD 1 , RAD 2 , RAD 3 ). An efficient allocation of resources to logical addresses is guaranteed as a result of changes to the assignment of partial amounts (A 1 , A 2 , A 3 ) of logical addresses (IP 1 , . . . , IPN) in AAA servers (RAD 1 , RAD 2 , RAD 3 ), according to need.
