22. A system for replicating IP address assignment changes in a distributed database having a plurality of nodes, comprising: a processor configured to: receive a semantic command at a first node having a first local version of the database, wherein the semantic command comprises a semantically expressed request to modify one or more IP address assignments in the database that allows for provisional modification of the first local version of the database before sending the semantic command to a master node having a master version of the database; provisionally apply the semantic command to the first local version of the database before sending the semantic command to the master node; reconcile the semantic command with the master version of the database, wherein reconciling the semantic command with the master version of the database includes determining whether the semantic command includes any IP address assignment changes that would result in an IP address assignment conflict with IP address assignment data stored in the master version of the database on the master node; and a memory coupled with the processor, wherein the memory provides the processor with instructions.

A system as recited in claim 22 , wherein the provisional modification comprises modifying the first local version of the database before reconciling the modification with the master node.
