Abstract: The present disclosure relates to application server access methods and terminals. One example method includes in response to a terminal failing to connect to an application server by using an IPv6 address, setting an accessed domain name to a restricted domain name, and, when the accessed domain name is re-accessed later, connecting to the application server by directly using an IPv4 address.
