Response to IPv4 address exhaustion and removing the need for NAT
| SLAAC | Stateless Address Auto Configuration |
|---|---|
Use the Subnet and add the EUI-64bit mac address ( = 48bit MAC@ + FFFE in the middle ) | |
| SLAAC does not provide the DNS IP@ ( it provide only the subnet in the RA packet ) | |
| Stateless DHCP | SLAAC (for IP@)+ DHCPv6 ( for DNS ) |
1- get the subnet from the RA 2- request the DNS to the DHCP server | |
| in RA ( from server ) | M ( managed address configuration ) = 1 address are mgt by DHCP server and if M = 0 then create your own IP address O ( other address ) = 1 you can ask for additional information to the DHCP server ( but IP addr won't be managed by the DHCP server ) |
| DHCPv6 | Stateful DHCPv6 |
DORA - - - - > SARC Use ICMPv6 packet No Broadcast > > > use All Nodes Multicast | |

RA: Router Advertisement | |
