In one embodiment, a flow control logic facilitates controlling modem prioritization and registration. The flow control logic controls an order in which stored DHCP requests are provided to a DHCP server. The DHCP requests may be stored in a plurality of groups in a data store. DHCP requests may be distinguishable based, at least in part, on priorities associated with cable modems from which DHCP requests are received. The priority may be determined by a value in the DHCP request. The flow control logic may control the rate and order at which stored DHCP requests are provided to the DHCP server.
