A method and system for automatic extension of a distributed numeric range in a multi-master system are described. In one embodiment, each of a plurality of master servers is provided with a unique range of numeric values that can be assigned to clients. Each master server can dynamically extend its associated range when the range is about to be exhausted. For example, a first master server can send a range request to a second master server to obtain additional numeric values when the number of values in its associated range is below a threshold. After receipt of the additional numeric values from the second master server, the first master server updates its associated range and assigns the additional numeric values to the clients.
