DHCPv6 Versus DHCPv4
The following lists the differences between DHCPv4 and DHCPv6:
• Unlike DHCPv4, IPv6 address allocation in DHCPv6 is handled
using a message option.
• The message types, such as DHCPDISCOVER and DHCPOFFER
supported by DHCPv4 are removed in DHCPv6. Instead, DHCPv6
servers are located by a client SOLICIT message followed by a server
ADVERTISE message.
• Unlike DHCPv4 clients, DHCPv6 clients can request multiple IPv6
addresses.
