SLAAC (Stateless Address Autoconfiguration) MAC is the process of automatically configuring IPv6 addresses on a network without the use of a DHCP server. When using SLAAC, each device generates its own unique IPv6 address by combining its interface identifier (based on its MAC address) with the network prefix advertised by the router.
For example, if a device has a MAC address of 00:11:22:33:44:55 and the network prefix advertised by the router is 2001:db8:1234::/64, the device’s IPv6 address would be:
2001:db8:1234::211:22ff:fe33:4455
In this example, the first 64 bits represent the network prefix and the last 64 bits are based on the device’s MAC address. The “ff” in between indicates that this is a modified EUI-64 format.
SLAAC MAC allows for easy configuration of IPv6 addresses on devices without requiring any additional infrastructure or management. It also provides improved security compared to manually configured addresses, as each device has a unique identifier in its IPv6 address. However, it does require that all devices on the network support IPv6 and have unique MAC addresses.
