To ease the management of a site, the Dynamic Host Configuration Protocol (DHCP) is often used. DHCP exists both for the Internet Protocol Version 4 (DHCPv4 for IPv4) and Version 6 (DHCPv6 for IPv6). To avoid possible pitfalls that occur if both DHCP versions are used and to avoid redundancy, IPv4 Information Options may be transmitted using DHCPv6 as described in this document. In dual-stack IPv4/IPv6 scenarios that employ DHCPv6, DHCPv4 can be completely replaced by using the DHCPv6 IPv4 Information Options.
