EUI 64:
The hostaddress is generated from the host's MAC-address, by setting the second beit in the second hexadecimal number of the MAC-adderss to high and adding FF:FE in the middle of the MAC-address.Example:
MAC: 00:1A:11:77:5B:CE
Host-Ad.: 02:1A:11:FF:FE:77:5B:CE
The problem about EUI64 is, that everyone is able to get your MAC-address (which always stays the same for your device). So companies can get more information about your behavior on the internet.
Random:
A 264 bit hostaddress is generated randomly.Static:
The hostddress is set manually at every host.Auto config:
The router sends a router advertisement. The router sends the network address to all notes. The host now knows the network address and its default gateway, because the sending address is also the link-local address.If the host does not want to wait for a router advertisement, it sends an all router multicast and asks for the network address. The router answers with an all notes multicast.
