3 DCN: 21-06-0511-00-0000-indication-ipaddress-conf Soohong Daniel Park, SAMSUNG Electronics. Overview MIH Function enables a mobile terminal to discover mobile terminal’s network address related information before handover. Several address configuration methods are available for both IPv4 and IPv6 mobile terminal to configure its address.  Static IPv4 address manually  Dynamic IPv4 address configuration (using DHCPv4)  Stateless IPv6 address configuration (using RFC2461)  Stateful IPv6 address configuration (using DHCPv6)  etc... If the IP mobile terminal recognizes its address configuration method before handover, it would be a useful information to prepare its address configuration.  DHCP Discover for DHCPv4  RS/RA exchange for Stateless Auto-Configuration  DHCP Solicit for DHCPv6  No message for address configuration

4 DCN: 21-06-0511-00-0000-indication-ipaddress-conf Soohong Daniel Park, SAMSUNG Electronics. IP Address Configuration IPv4 address can be typically configured by either DHCPv4 or static method.  DHCPv4 is dominant method than static when in motion. IPv6 address can be configured by either stateless method or stateful method.  Stateless method: RFC2461  Stateful method: RFC3315 (DHCPv6) IPv6 Prefix is not mandate for all router If no prefix  Don’t need to do a stateless configuration. (RS/RA exchange)  Rather, a mobile node should send a DHCPv6 DISCOVER message to obtain its IPv6 address. Stateful IPv6 configuration regardless of prefix  Admin manageable IPv6 allocation
