When being converted to the destination IP address v4, due to prefix information (such as prefix length, prefix addresses) difference, it may make with extracting IPv4
It misplaces when location, that is, extracts the address IPv4 of mistake, so that the message of forwarding can not be correctly sent to IPv4 and set
It is standby, cause IPv4 equipment to have not been able to response IPv6 equipment.
Both in this case, by comparing the address initial IP v4 and the address converted destination IP v4, can pass through
Difference determines that the converted address destination IP v4 is incorrect.
For another example, address-translating device also needs IPv6 protocol massages being converted to IPv4 protocol massages after receiving message,
It thus needs to modify to the part field of message, such as IP layers and tcp layers of modification of checksum, modifies IP header parameter
Deng, and if checksum calculates mistake, the IPv4 protocol massages parameter error that will modification obtained, thus even if being converted
The address destination IP v4 it is correct, IPv4 protocol massages can be sent to IPv4 equipment, which still will be unable to correctly respond.
Both in this case, by comparing the address initial IP v4 and the address converted destination IP v4, can still pass through
It is identical, determine that the converted address destination IP v4 is correct.
As it can be seen that pre-set address can be passed through in address conversion detection scheme provided by this specification embodiment
