Address database

The address database contains information about the addresses currently allocated by the AAS. The address server maintains this database in memory and records changes to it in a transaction log, which it stores on disk. At startup, the address server rebuilds the address database from the transaction log. When the transaction log reaches the ``database compression size'' (see ``AAS configuration database'') the address server compresses the transaction log by writing a new file containing the current allocation information.
The address database contains the following information about each allocated address:

• Time when the address was reserved

• The lease

• Time when the address was released

• Name of the service that reserved an address

• Identifier of the client using the address (for example, the client identifier for a DHCP client is the client's subnet number, hardware type and hardware address).
