Question 3

Provide a high-level description of the address selection process from end-to-end.

Accepted Answer

Here's a high-level description of the end-to-end process of Node1 communicating to a remote host:
1. The operator on Node1 uses an application to send a message to a remote Web server, querying the remote host for its configured addresses.
2. The remote host replies with multiple addresses, including one IPv4 address and several IPv6 addresses.
3. Node1 uses the source address selection algorithm to select the most preferred source address to use with each of the remote host's IPv6 destination addresses.
4. Node1 uses the destination address selection algorithm to sort the IPv4 and IPv6 destination addresses in order of preference.
5. The application used by Node1's operator is provided with the ordered destination addresses and their related source addresses.
6. The application attempts to use the source/destination address pairs until a set of addresses is successful in establishing communications with the remote host.
