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 | |
| DHCPv6 | Statefull DHCPv6 |
DORA - - - - > SARC Use ICMPv6 packet No Broadcast > > > use All Nodes Multicast | |
