At present, there are two ways for a terminal device (such as a mobile phone and a computer) to dynamically acquire a unicast IPv6 address, which are stateful management configuration and stateless automatic configuration respectively, and when the stateful management configuration is performed, the terminal device receives an IPv6 address carried in a DHCPv6 message of a Router and configures the received IPv6 address to an internet access card, and when the stateless automatic configuration is performed, the terminal device automatically generates the IPv6 address according to prefix information included in a Router Advertisement RA (Router Advertisement) message of a gateway (i.e., the Router) and a suffix information (EUI 64 or random generation) and configures the IPv6 address to the internet access card.
However, if the gateway wants to acquire the IPv6 address of the terminal device connected below the gateway, if the stateless IPv6 address automatic configuration method is used, the IPv6 address of the terminal device cannot be directly counted, because the terminal device is the IPv6 address formed by autonomously combining a prefix and a suffix of a certain rule, and in conclusion, the method for acquiring the IPv6 address in the prior art is very inconvenient.

Based on the above-mentioned superior device, embodiments of the IPv6 address acquisition method of the present invention are presented.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for acquiring an IPv6 address according to a first embodiment of the present invention. In a first embodiment of the method for acquiring an IPv6 address of the present invention, the method for acquiring an IPv6 address of the present invention includes:
step S10: acquiring message data, and determining whether the type of the message data is a duplicate address detection message;
in this embodiment, when the higher-level device acquires the IPv6 address of the terminal device, the message data is acquired, and then it is determined whether the type of the message data is a duplicate address detection message.
It should be noted that the upper-level device is a gateway (router), the terminal device is a device such as a mobile phone or a computer that can access the internet, the Duplicate Address Detection (DAD) message is a special NS (neighbor solicitation protocol) message, the sixth version of internet protocol is IPv6, and the sixth version of internet protocol Address is an IPv6 Address.
The duplicate address detection mechanism is performed before an interface uses a certain IPv6 unicast address, and mainly aims to detect whether other nodes use the address or not, after a terminal network card obtains the unicast IPv6 address, the terminal network card is marked as a test address, then an NS (neighbor solicitation protocol) message is sent, an option field of the NS carries the unicast address, a destination address is a multicast address of a requested node corresponding to the address, if no NA (neighbor advertisement protocol) message for replying the NS message exists in a link within a period of time or no NS message with the same structure is received, the test address to be used is considered to be not occupied by other host nodes in a local link range, the invalid address is converted into an effective address, the address configuration is effective, if the NA message for replying the NS message or the NS message with the same structure is received, the duplicate address detection fails, the test address is converted into an illegal address and cannot be used by the node, namely, the IPv6 address to be configured and used is carried when the NS is sent, therefore, after the message data in the link is obtained, whether the type of the message data of the duplicate address detection message is determined, and whether the IPv6 message is carried, thereby detecting whether the IPv6 address or not.
Optionally, in some possible embodiments, the step of "acquiring message data" in step S10 may include the following steps:
step S101: confirming whether a message signal exists or not through a socket;
illustratively, as shown in the flow of fig. 3, in this embodiment, the upper level device establishes an original socket, where the socket is a socket (PF _ PACKET, socket _ RAW, htons (ETH _ P _ ALL)), and is configured to receive ALL data PACKETs on the network card, and after using the socket, a text descriptor may be obtained, and then it is monitored whether data arrives in the file descriptor, where the process is select, and finally, message data sent from the file descriptor is received, and the process is recvfrom.
Step S102: and if the message signal is confirmed, reading the message signal to acquire message data.
In this embodiment, after the gateway determines whether there is a message signal through the socket, if it is determined that there is the message signal, the gateway reads the message signal to obtain the message data.
It should be noted that, as shown in the flowchart of fig. 3, while represents a loop, after the gateway acquires the IPv6 address, or after the gateway fails to acquire the IPv6 address, the IPv6 address of the next message information is acquired in a loop, and if a message signal is confirmed, the message signal is read to acquire message data, where the process is process data.
Step S20: if the message data is confirmed to be a duplicate address detection message, detecting whether a target address of the message data carries a polymerizable global unicast address;
in this embodiment, the gateway obtains the message data, determines whether the type of the message data is a duplicate address detection message, and further detects whether the destination address of the message data carries a polymerizable global unicast address if it is determined that the type of the message data is a duplicate address detection message.
It should be noted that the aggregatable global unicast address is a common IPV6 address that can be used on the public network, and the message data may be addresses of other types, so that the gateway acquires the message data, determines that the message data carries the IPV6 address by determining that the type of the message data is a duplicate address detection message, and then further determines that the destination address of the message data carries a aggregatable global unicast address, thereby determining that the destination address is an IPV6 address.
It should be noted that, as shown in the flowchart of another embodiment shown in fig. 3, the target address is a target address, the polymerizable global unicast address is a GUA, and whether the target address of the message data carries the GUA is detected.
Step S30: and when the target address is detected to carry the polymerizable global unicast address, confirming that the target address is the IPv6 address.
In this embodiment, if the gateway determines that the packet data is a duplicate address detection packet, it further determines whether the destination address of the packet data carries a polymerizable global unicast address, and when it is detected that the destination address carries the polymerizable global unicast address, it determines that the destination address is an IPv6 address.
Exemplarily, if the confirmation target address 3333 00000000.
It should be noted that, after the gateway determines that the destination address is an IPv6 address, the gateway stores a source MAC (media access control) and the destination address in the DAD message data together, so that the user can query the GUA address of the device through the MAC when querying the IPv6 address later.
Thus, in this embodiment, when the IPv6 address of the terminal device is obtained by the upper device, the message data is obtained, and then it is determined whether the type of the message data is a duplicate address detection message; then, the gateway acquires the message data, confirms whether the type of the message data is a duplicate address detection message, and further detects whether the target address of the message data carries a polymerizable global unicast address if the type of the message data is the duplicate address detection message; and finally, if the gateway confirms that the message data is a duplicate address detection message, further confirming whether a target address of the message data carries a polymerizable global unicast address, and when detecting that the target address carries the polymerizable global unicast address, confirming that the target address is an IPv6 address.
The method and the device can confirm whether the type of the message data is the repeated address detection message or not by acquiring the message data, and detect whether the target address of the message data carries the polymerizable global unicast address or not, and confirm that the target address is the IPv6 address when the type of the message data is the repeated address detection message and the target address of the message data carries the polymerizable global unicast address, namely, the unicast IPv6 address can be acquired at any time no matter in any state, such as a state, a non-state or manual configuration, and the like, thereby improving the convenience for acquiring the IPv6 address to a great extent.
Optionally, based on the above first embodiment of the method for acquiring an IPv6 address of the present invention, a second embodiment of the method for acquiring an IPv6 address of the present invention is provided.

It should be noted that, in this embodiment, as shown in the flowchart in fig. 3, the version type is ether _ type, it should be understood that the message data may be IPv4 (fourth version internet protocol address), and therefore, whether the version of the message data is IPv6 is determined by whether ether _ type is correct or not,

In this embodiment, after the gateway obtains the version type of the message data and detects whether the version type of the message data is the sixth internet protocol, if it is detected that the version type is the sixth internet protocol, it is determined that the version type of the message data is correct.
It should be noted that, if the gateway determines that the protocol version type of the message data is incorrect, that is, if the gateway determines that the version type of the protocol message data is not IPv6, the gateway acquires the IPv6 address of the next message data.
Step S102: if the version type is detected to be correct, detecting whether the next header protocol type of the message data is correct;
in this embodiment, after detecting whether the version type of the message data is correct, if the version type of the message data is correct, the gateway detects whether the next header protocol type of the message data is correct.
It should be noted that, in this embodiment, as shown in the flowchart of another embodiment shown in fig. 3, the next header Protocol type is a next header, it should be understood that whether the type of the Message data is ipcmv6 is determined by whether the next header is correct, icmpv6 (Internet Control Message Protocol Version 6, next header Protocol type in sixth edition) is one of the basic protocols of IPv6, icmpv6 is placed behind IPv6, the target basic Protocol is ICPMv6, whether the next header is ICPMv6 is determined, whether the Message data is likely to be an NS Message is determined, and if the next header is ICPMv6, the Message data is likely to be an NS Message, specifically, the Protocol number of ICPMv6 in IPv6 is 58, and whether the type of the next header is correct is also determined by determining whether the Protocol number of IPv6 is 58.
Optionally, in some possible embodiments, the step of detecting whether the next header protocol type of the message data is correct in step S102 includes the following steps:
step S1021: acquiring a next header protocol type of the message data, and detecting whether the next header protocol type is a target basic protocol;

In this embodiment, the gateway obtains the next header protocol type of the message data, and detects whether the next header protocol type is the target base protocol, and if it is detected that the next header protocol type is the target base protocol, it detects that the next header protocol type of the message data is correct.
It should be noted that, if the gateway determines that the next header protocol type of the message data is incorrect, that is, if the gateway determines that the next header protocol type of the message data is not ICMPv6, the gateway acquires the IPv6 address of the next message data.
Step S103: if the next header protocol type is detected to be correct, detecting whether the source address of the message data is correct;
in this embodiment, after detecting whether the next header protocol type of the message data is correct, the gateway detects whether the source address of the message data is correct if the next header protocol type is correct.

in this embodiment, after detecting whether the source address of the message data is correct, the gateway acquires the usage type of the message data if it is detected that the source address is correct, and detects whether the usage type is a neighbor solicitation protocol.
It should be noted that, as shown in the flowchart of another embodiment shown in fig. 3, the neighbor solicitation protocol is NS, and after detecting whether the source address of the message data is correct, if it is detected that the source address is correct, it obtains whether the usage type of the message data is NS, where it is to be noted that, the ICMPv6 message (that is, NS message) whose usage type of the duplicate address detection message is 135 is detected, and by detecting whether the usage type of the message data is 135, it is determined whether the usage type of the message data is NS.
