For these server address, in A recording address list, communication terminal preferentially select first address in address list into
Row communication.For AAAA recording address list, communication terminal can also similar selection.This selection mode is usually communication terminal
Default mode.Between first address of A recording address list and first address of AAAA recording address list, such as
The standard documents such as RFC3484, windows operating system etc., all default preferential selection address IPv6 of support.When application server
The address IPv6 is reachable, and the communication process between communication terminal and application server can be set up quickly.Work as application server
The address IPv6 it is unreachable, communication terminal can continuous repeated attempt and application server establish and communicate to connect, or switch and taste
The address IPv4 for trying application server, until communication terminal finally determines reachable server address or whole server address
It is all unreachable.Whole cut-and-try process may cause up to tens seconds time delays, will affect user experience when serious.
