[多选] A Company is using 6to4 tunnels in their IPv6 network. Which two statements are true about thesetunnels？（）

A . In a 6to4 tunnel， the first two bytes of the IPv6 address will be 0x2002 and the next four byteswill be the hexadecimal equivalent of the IPv4 address
B . In a 6to4 tunnel， the IPv4 address 192.168.99.1 would be converted to the2002：1315：4463：1：：/64 IPv6 address
C . In a 6to4 tunnel， the IPv4 address 192.168.99.1 would be converted to the 2002：c0a8：6301：：/48IPv6 address
D . In a 6to4 tunnel， the first two bytes of the IPv6 address will be locally derived and the next twobytes will be the hexadecimal equivalent of the IPv4 address
E . In a 6to4 tunnel， the IPv4 address 192.168.99.1 would be converted to the 2002：c0a8：6301：：/16IPv6 addre
