Same is true for a host with two IPv4 addresses and either of the IPv4 addresses have problems. Same is true for a host with two IPv6 addresses and either of the IPv6 addresses have problems. The problem can be solved by carefully designing connection establishment protocols to support multiple addresses of a host, which means no solution exists at the connectionless layer of IP. Modified TCP, which send multiple SYN to several addresses of a peer helps a lot to reduce timeout.
