1. A method, comprising:
maintaining, by a network device and for a user device, a pool domain into which address prefixes are allocated from a partition of an address pool management (APM) device;
estimating, by the network device and based on pool domain data, an average subscriber login rate for the pool domain by the user device;
estimating, by the network device and based on the pool domain data, an average response latency per apportionment alarm;
calculating, by the network device, a dynamic apportionment threshold based on the average subscriber login rate for the pool domain and the average response latency per apportionment alarm;
calculating, by the network device and based on the dynamic apportionment threshold and a size of the pool domain, a quantity of prefixes to request from the APM device; and
utilizing, by the network device, the quantity of prefixes for the user device.
