IPv6 Configurations

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.

DAD: Duplicate Address Detection

The host sends a multicast to see if another host has the same IP-Address. If it gets an answer, the host stops and waits for the superuser to do something.


8.3.1.4 Implementing a Subnetted IPv6 Addressing Scheme

 

In this exercise you should practice configuring PCs with IPv6 Auto Config. To make the network below work, you have to configure the IPv6 address of the interfaces on the two routers like we did in the last exercise. But before you can do this, you have to fill in the addressing table like the one shown below.
