The invention includes a method and apparatus for assigning an IP address to a mobile node (MN) from an IP address space represented using an address aggregation tree. A method includes receiving a request for an IP address for the MN, identifying each of a plurality of sub-tree gaps in the address aggregation tree, selecting one of the identified sub-tree gaps, and assigning an available IP address from the selected sub-tree gap to the MN. The sub-tree gaps of the address aggregation tree are identified using a recursive algorithm that traverses the address aggregation tree. The selected one of the sub-tree gaps is selected based on respective sizes of the identified sub-tree gaps. The assigned IP address is communicated to the MN for use by the MN in accessing various services.
