T. Lemon: AUTHOR [+1]
The DHCPv4 [RFC2131] and DHCPv6 [RFC3315] protocol specifications describe how addresses can be allocated to clients based on network topology information provided by the DHCP relay infrastructure. Address allocation decisions are integral to the allocation of addresses and prefixes in DHCP.
