The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all 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 application.
Referring to fig. 1, which shows a flowchart of a method for detecting a continuously available IP address according to an embodiment of the present application, the method for detecting a continuously available IP address according to an embodiment of the present application may include:
s11: and acquiring continuous IP addresses distributed to the target data center machine room, and numbering the continuous IP addresses continuously.
When detecting the continuously available IP addresses, first, a target data center room to be detected the continuously available IP addresses needs to be determined. The determining method may specifically be that a user sends a query command of the continuously available IP addresses of the target data center computer room (the query command may include information such as an identifier or a name of the target data center computer room), and then, the target data center computer room is determined according to the received query command of the continuously available IP addresses of the target data center computer room sent by the user, or of course, the target data center computer room may also be obtained through automatic query.
After the target data center room is determined, the continuous IP addresses allocated to the target data center room may be automatically obtained, where the continuous IP addresses mentioned herein may be specifically allocated to the target data center room by the system, or may be allocated by a user of the target data center room actively.
After the continuous IP addresses allocated to the target data center room are automatically obtained, the continuous IP addresses allocated to the target data center room may be automatically numbered: first, first +1, … …, last, and specifically refer to fig. 2, which shows a schematic diagram of consecutive numbers corresponding to consecutive IP addresses allocated to a target data center computer room according to an embodiment of the present application, that is, a first IP address in the consecutive IP addresses is numbered as first, and a second IP address in the consecutive IP addresses is numbered as first +1 … …, so as to detect continuously available IP addresses according to the consecutive numbers of the consecutive IP addresses, and improve convenience and accuracy of detecting the continuously available IP addresses by continuously numbering the consecutive IP addresses.
In order to improve the convenience of detection, first +1, … …, last are integers, and the value of first may be 1 or not 1, that is, when consecutive IP addresses are assigned, consecutive IP addresses may be numbered from 1 according to 1, 2, … … (i.e., the first IP address in the consecutive IP addresses is numbered as 1, and the second IP address in the consecutive IP addresses is numbered as 2 … …), or from an integer (e.g., 2) not equal to 1 according to 2, 3, … … (i.e., the first IP address in the consecutive IP addresses is numbered as 2, and the second IP address in the consecutive IP addresses is numbered as 3 … …).
Through the above-mentioned serial numbering of the continuous IP addresses, the corresponding relation between each IP address in the continuous IP addresses and the serial number can be obtained, so that the detection of the continuously available IP addresses can be conveniently carried out based on the corresponding relation.
S12: and acquiring IP addresses in the continuous IP addresses occupied by the physical nodes in the target data center machine room, and recording the numbers corresponding to the occupied IP addresses in the continuous IP addresses in the used array.

Then, the occupied IP address corresponding number in the continuous IP addresses can be determined according to the corresponding relation between the IP addresses and the numbers in the continuous IP addresses, and the number corresponding to the occupied IP address in the continuous IP addresses is recorded in the used array. Where used [ i ] indicates that the IP address is already occupied and the used array may be unordered.
After the used array is obtained, the number of the numbers existing between any two adjacent numbers in the numbers contained in the used array is the number of the continuously available IP addresses, so that the determination of the maximum continuously available IP address information can be performed subsequently through the used array.
S13: adding a minimum record number and a maximum record number in the used array according to the minimum number and the maximum number corresponding to the continuous IP addresses; the minimum record number is 1 smaller than the minimum number, and the maximum record number is 1 larger than the maximum number.
Considering that only the number corresponding to the occupied IP address in the consecutive IP addresses is recorded in the used array used and the maximum consecutive available IP address is determined, the first IP address and the last IP address in the consecutive IP addresses are ignored, that is, the IP addresses numbered first and last are ignored, so in order to improve the accuracy of detecting the maximum consecutive available IP address information, the minimum record number and the maximum record number may be added in the used array used according to the minimum number and the maximum number corresponding to the consecutive IP addresses, specifically, the minimum record number added in the used array used is less than 1 than the minimum number corresponding to the consecutive IP addresses, that is, the minimum record number added in the used array used is less than 1 than first, that is, the minimum record number added in the used array used is first-1; the maximum record number added in the used array is 1 greater than the maximum number corresponding to the consecutive IP addresses, that is, the maximum record number added in the used array is 1 greater than last, that is, the maximum record number added in the used array is last + 1. For example: assuming that the used array used obtained in step S12 is used ═ b, a, d, c … … ], the used array used obtained after step S13 is used ═ first-1, b, a, d, c … …, last + 1.
S14: and determining the maximum continuous available IP address information corresponding to the target central computer room according to the used array.

According to the process, the continuous IP addresses are automatically numbered continuously, the numbers corresponding to the occupied IP addresses in the continuous IP addresses are automatically recorded in the used array, the minimum record number and the maximum record number are automatically added in the used array, and the last continuous available IP address information corresponding to the target center machine room is automatically, quickly and accurately detected without manual participation.
According to the technical scheme disclosed by the application, the IP addresses in the continuous IP addresses occupied by the physical nodes in the target data center machine room are obtained by continuously numbering the continuous IP addresses allocated to the target data center machine room, the numbers corresponding to the occupied IP addresses in the continuous IP addresses are recorded in the used array, the minimum record number which is smaller than the minimum number corresponding to the continuous IP addresses by 1 and the maximum record number which is larger than the maximum number corresponding to the continuous IP addresses by 1 are added in the used array, and the maximum continuously available IP address information corresponding to the target center machine room is determined according to the used array so as to realize the automatic detection of the maximum continuous IP addresses without manual participation, so that the labor consumption in the detection process of the maximum continuous IP addresses is reduced, the detection efficiency and the detection accuracy of the maximum continuous IP addresses are improved, and the quick deployment and the online of the application are convenient to realize, the stability of the data center is guaranteed, the management cost investment of the data center is reduced, and the user experience is improved.
The method for detecting continuously available IP addresses provided in the embodiment of the present application, determining the maximum continuously available IP address information corresponding to a target central computer room according to a used array, may include:

and determining the IP address corresponding to the maximum number of the continuous available IP addresses according to the two adjacent numbers corresponding to the maximum number in the sorted used array and the numbers corresponding to the continuous IP addresses.
In the present application, when determining the maximum consecutive available IP address information corresponding to the target central equipment room according to the used array, in order to improve convenience and efficiency of determining the maximum consecutive available IP address information corresponding to the target central equipment room, the numbers included in the used array may be sorted according to a size order (specifically, according to a sequence from small to large, or according to a sequence from large to small) to obtain the sorted used array. Then, the number of numbers included between two adjacent numbers in the sorted used array may be obtained, for example: assuming that there are two numbers 2 and 6 adjacent to each other in the sorted used array, it can be determined that the number of numbers included between the two adjacent numbers is 3. And after the number of the numbers contained between every two adjacent numbers in the sorted used array is determined, determining the maximum number of the numbers as the maximum number of the continuous available IP addresses corresponding to the target central computer room. Meanwhile, the IP addresses corresponding to the maximum number of the continuously available IP addresses can be determined according to the two adjacent numbers corresponding to the maximum number in the sorted used array and the numbers corresponding to the continuous IP addresses (namely, the numbers corresponding to the IP addresses in the continuous IP addresses respectively, namely, the corresponding relation between the IP addresses and the numbers in the continuous IP addresses), and specifically, the IP address corresponding to the number existing between the two adjacent numbers corresponding to the maximum number in the sorted used array is determined as each IP address corresponding to the maximum number of the continuously available IP addresses, so that the related personnel can know the maximum number of the continuously available IP addresses corresponding to the target data center machine room, and can also determine each IP address corresponding to the maximum number of the continuously available IP addresses, and the related personnel can conveniently perform subsequent operation based on the information, The preparation is used.
For example: for simplicity, assuming that a certain target data center room is allocated with 8 consecutive IP addresses, and the 8 numbers 2-9 are obtained by consecutively numbering the 8 consecutive IP addresses, wherein the IP addresses with numbers 4 and 6 are occupied, the sorted used array is [1,4,6,10] obtained by recording, adding the minimum record number and the maximum record number, and sorting, and the two numbers 2 and 3 included between the adjacent two numbers 1 and 4 in the sorted used array are obtained, the number 5 included between the adjacent two numbers 4 and 6 in the sorted used array is obtained, the three numbers 7, 8, and 9 included between the adjacent two numbers 6 and 10 in the sorted used array are obtained, and thus, the maximum number 3 can be obtained, at this time, it may be determined that the maximum number of consecutive available IP addresses corresponding to the target central equipment room is 3, and the IP address corresponding to the maximum number of consecutive available IP addresses may be determined according to two adjacent numbers, 6 and 10, corresponding to the maximum number of 3 in the sorted used array, and the number corresponding to the consecutive IP address, specifically, the IP address corresponding to the three numbers, 7, 8, and 9, existing between the two adjacent numbers, 6 and 10, is determined as the IP address corresponding to the maximum number of consecutive available IP addresses.

Of course, the number of the numbers contained in the two adjacent numbers can also be obtained by directly subtracting the smaller number from the larger number and then subtracting 1 from the smaller number in the two adjacent numbers in the used array.
The number of the numbers contained between two adjacent numbers in the sorted used array can be quickly calculated by the method.
Taking the example that the used arrays after the sorting are obtained by sorting the numbers included in the used arrays from small to large in the present application, the core code for obtaining the maximum number of numbers included between two adjacent numbers in the used arrays after the sorting is specifically as follows:
