Scene 1, PC are XP systems, only support IPv4 agreement, and user uses pc access domain name, and initiation is A inquiry.If
CPE agency first sends AAAA inquiry, and the address that AAAA has inquired IPv6 returns to PC, but PC does not support IPv6, can not make
With the address IPv6 that this is inquired, it may also need to initiate A inquiry again, cause query process slack-off.
Scene 2, PC are WIN7 systems, support IPv4/v6 agreement, and user uses pc access domain name, and initiation is that AAAA is looked into
It askes.If CPE agency first sends AAAA inquiry toward IPv4DNS server, and general IPv4DNS server does not support AAAA
Record returns to failure, and CPE can only be inquired toward the switching of next dns server again according to polling schemas, can until being polled to
IPv6 server.The consuming time is longer in this way, and user experience is very poor.
Certainly, the also problem same with the presence of other application scenarios is first dealt into that is, when inquiring A or AAAA and recording
