These tests should be in CI, or they should be repeated after each change. We should support the following combinations of address literals and hostnames: Legacy configurations: A. No configured Address option B. Address IPv4 literal C. Address hostname (use IPv4 and IPv6 DNS addresses) New configurations: D. Address IPv6 literal E. Address IPv4 literal / Address IPv6 literal F. Address hostname / Address hostname (use IPv4 and IPv6 DNS addresses) G. Address IPv4 literal / Address hostname (only use IPv6 DNS addresses) H. Address hostname (only use IPv4 DNS addresses) / Address IPv6 literal If we can't find an IPv4 or IPv6 address using the configured Address options: * No IPv4: guess IPv4, and its reachability must succeed. * No IPv6: guess IPv6, publish if reachability succeeds. Combinations A and B are the most common legacy configurations. We want to support the following outcomes for all legacy configurations: * automatic upgrades to guessed and reachable IPv6 addresses, * continuing to operate on IPv4 when the IPv6 address can't be guessed, and * continuing to operate on IPv4 when the IPv6 address has been guessed, but it is unreachable.
