In a multi-unit building, a DHCP service receives a DHCP request from a user attempting to connect to the internet. A database associates a user's MAC address with an ISP identifier, and uses same to assign an available IP address from a pool of IP addresses that correspond to the ISP identifier. Databases that associate MAC addresses with ISPs, and a pool of IP addresses with each of the multiple ISPs, may reside on a DHCP server locally at the multi-unit building, or remote from the building at an ISP's local DHCP server. Thus, even if the building only has a single distribution network for providing broadband access, users at the building can choose access to the internet from among multiple ISPs having a contract with the building's management, rather than being stuck using only a single ISP that has a contract with the building's management.
