Through NDP routing prefix advertisements, a router or server host may announce configuration information to all link-attached interfaces which causes additional IP address assignment on the receiving interfaces for local or global routing purposes.
This process is sometimes also considered stateless, as the prefix server does not receive or log any individual assignments to hosts.
If a reply is received to the ARP, it indicates the candidate IP address is already in use; a new random candidate IP address is then created and the process repeated.
The process ends when there is no reply to the ARP, indicating the candidate IP address is available.
Uniqueness is guaranteed automatically by the address selection methodology.
It may be MAC-address based according to RFC 4862, or randomized according to RFC 4941.Therefore, hosts search for a DHCP server on the network before assigning link-local addresses.In the automatic address configuration process, network hosts select a random candidate address within the reserved range and use Address Resolution Protocol (ARP) probes to ascertain that the address is not in use on the network.It is okay if it is a little different than what you see below.Once the dock's network service has been added to your list of possible network connections, you have the option to change the order in which your Mac Book will use this service.The service associated with your Horizontal Dock will be listed as Thunderbolt Ethernet Slot followed by a number.Please note that there may be slight variations to the service title as each Mac Book reports differently.Click on the Gear Icon drop-down menu, as illustrated below, and then drag the ethernet connection to the top-most position in the list and click OK Please note: The final step is not always necessary but may be helpful to establish a more reliable connection.Remember, nothing done here is permanent and you can always change it back if necessary.For Internet Protocol (IP) networks, they are assigned most often using stateless address autoconfiguration.In IPv4, they are normally only used to assign IP addresses to network interfaces when no external, stateful mechanism of address configuration exists, such as the Dynamic Host Configuration Protocol (DHCP), or when another primary configuration method has failed.
