The present invention provides dynamic pool sharing to allow subnets (130, 140) with DHCP servers to borrow IP addresses when subnet capacity requirements reach preexisting limits and assign the IP addresses to DHCP clients (135, 136, 145). Specifically, the network relies on adjacent subnets to share IP addresses so DHCP clients (135, 136, 145) coupled to mobile devices remain coupled to a wireless network. A DHCP client (135, 136, 145) requests an IP address. A home subnet subnets (130, 140) requests pool sharing with adjacent subnets subnets (130, 140) and selects a candidate among the adjacent subnets subnets (130, 140). The home subnet subnets (130, 140) then negotiates the selected candidate with the DHCP client (135, 136, 145). |
