Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The invention is further described with reference to the following drawings and specific examples, which are not intended to be limiting.
The IPv6 address survivability scanning system based on traffic analysis provided in the embodiment of the present invention is configured to scan an IPv6 address and perform traversal scanning on the scanned surviving IPv6, and referring to fig. 1, the IPv6 address survivability scanning system includes:
an IPv6 address obtaining module 1, configured to obtain an IPv6 address;
the IP address category judging module 2 is connected with the IPv6 address obtaining module 1 and used for judging whether the obtained IPv6 address is a real IPv6 address or not;
the IP address survivability judging module 3 is connected with the IP address type judging module 2 and is used for judging the survivability of the IPv6 address confirmed to be real;
the IP address traversal range determining module 4 is connected with the IP address survivability judging module 3 and used for determining an IPv6 address traversal range according to the IPv6 address judged to be alive;
the IP address traversal module 5 is respectively connected with the IP address traversal range determining module 4 and the IP address survivability judging module 3 and is used for performing traversal scanning on the IPv6 addresses in the IPv6 address traversal range, and then the IP address survivability judging module 3 performs survivability judgment on all the IPv6 addresses which are traversed and scanned to obtain an IPv6 address survivability judging result;
and the IP address storage module 6 is connected with the IP address viability judging module 3 and is used for storing each IPv6 address judged to be viable.
The IPv6 address survivability scanning system provided in this embodiment has multiple IPv6 address obtaining manners, please refer to fig. 2 specifically, where the IPv6 address obtaining module 1 specifically includes:
a domain name resolution unit 11, configured to obtain an IPv6 address in a domain name resolution manner;
an IPv6 address generating unit 12, configured to randomly generate a suffix address of IPv6 according to the prefix of the IPv6 address pool, and finally generate an IPv6 address;
the IPv6 address calculating unit 13 is used for calculating to obtain a corresponding IPv6 address according to the IPv6 address base prefix and the network card MAC address;
the first IPv6 address obtaining unit 14 is configured to obtain, by obtaining the routing information of the routing device, IPv6 addresses corresponding to devices connected to the routing device.
A second IPv6 address acquiring unit 15, configured to acquire, through an SNMP protocol (network management protocol), a plurality of IPv6 addresses that are attached to the IPv6 device.
In the above technical solution, domain name resolution refers to pointing a domain name to a website space IP, that is, a domain name mapping IP address, and acquiring an IPv6 address in a domain name resolution manner is an existing IP address acquisition manner, and a specific acquisition process thereof is not described herein.
Because the encoding forms of the IPv6 address and the IPv4 are not consistent, the IPv6 address can be finally determined by randomly generating an IPv6 suffix address after determining the prefix of the IPv6 address base. And then the system carries out subsequent survivability judgment on the IPv6 address generated randomly.
The MAC address (local area network address) and the IP address have certain relevance, so that the real IPv6 address can be obtained by reverse estimation based on the MAC address and the prefix of the IPv6 address base.
For example, the MAC address of the device is 00-AA-00-3F-2A-1C, when the MAC address is converted into an EUI-64 address of 00-AA-00-FF-FE-3F-2A-1c, and the EUI-64 address is converted into an IPv6 address, the first byte is 00000000, the 7 th bit of the first byte is inverted to 00000010, the 16 th bit is converted to 0x02, and the final conversion result is 02-AA-00-FF-FE-3F-2A-1C, and the converted IPv6 address is finally obtained and expressed as 2aa.
In this embodiment, the IPv6 address survivability scanning system preferably performs survivability judgment on the obtained IPv6 address by using an ICMP (Internet Control Message Protocol) detection mode.
The ICMP detecting method determines whether an IP address is a live address, and the specific detecting process is not described herein.
The larger the traversal range of the IP address is, the more traversal scan time is required, and in order to implement fast traversal scan of the IPv6 address, preferably, the traversal range of the IPv6 address is:
and traversing 1-15 IPv6 addresses in sequence forwards or backwards by taking the IPv6 address judged to be alive as a traversal initial address, and certainly traversing 1-15 IPv6 addresses before and after traversing. The traversal range can be preset according to actual needs.
Referring to fig. 3, the present invention further provides a method for IPv6 address survivability scanning based on traffic analysis, which is implemented by applying the above-mentioned IPv6 address survivability scanning system, and specifically includes the following steps:
s1, an IPv6 address survivability scanning system acquires an IPv6 address;
step S2, the IPv6 address viability scanning system judges whether the acquired IPv6 address is a real IPv6 address or not,
if yes, the step S3 is carried out;
if not, the scanning process is terminated;
step S3, the IPv6 address survivability scanning system judges the survivability of the IPv6 address confirmed to be real,
if the IPv6 address is alive, the step S4 is carried out;
if the IPv6 address does not survive, the scanning process is terminated;
s4, the IPv6 address survivability scanning system determines an IPv6 address traversal range according to the IPv6 address judged to be alive;
step S5, the IPv6 address survivability scanning system conducts traversal scanning on all IP addresses in the IPv6 address traversal range and judges whether all IPv6 addresses in the IPv6 address traversal range are surviving addresses or not,
if yes, storing the IPv6 address judged to be alive;
if not, the address scanning is finished.
In the above technical solution, in order to extend the range of performing survivability scanning on the IPv6 address, more preferably, in step S5, the IPv6 address survivability scanning system will continue to perform further traversal scanning on the IPv6 addresses determined to be alive in the IPv6 address traversal range. That is, for example, in the process of first traversal scanning, if the system finds that a plurality of surviving addresses exist in the traversal range of the IPv6 address, for example, 3 surviving IPv6 addresses exist, the system returns to step S4, determines the traversal range of the IPv6 address for the three surviving IPv6 addresses respectively, then performs traversal scanning on each IPv6 address again, and performs IPv6 address survivability judgment on the traversal scanning result until a scanning stop signal of the user is received to stop scanning.
The multiple traversal scanning is favorable for expanding the range of survivability scanning, is also a sequential verification process of the last traversal scanning result, and is favorable for improving the accuracy of the traversal scanning result.
In the above technical solution, in step S3 and step S5, the method for determining whether the IPv6 address is a live address includes, but is not limited to, an ICMP detection method, where the ICMP detection method is an existing IP address liveness determination method, and a specific determination process thereof is not described herein.
In order to increase the speed of traversal scanning, preferably, the IPv6 address traversal range in step S4 is:
and traversing 1-15 IPv6 addresses in sequence forwards or backwards by taking the IPv6 address confirmed as the survival as the traversal initial address. Of course, 1-15 IPv6 addresses can be traversed forwards and backwards at the same time.
In addition, it should be noted that the process of acquiring the IPv6 address is an IPv6 address acquisition process based on traffic analysis. The traffic generated by domain name resolution, MAC address data, routing information, data generated by acquiring IPv6 addresses through the SNMP protocol, and the like are all the traffic.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
