Example one
Fig. 1 is a flowchart of a method for determining an area to which an IP address belongs according to an embodiment of the present application. The method and the device for determining the IP address can be applied to the situation of determining the region to which the IP address belongs. The method can be executed by a device for determining the area to which the IP address belongs, which can be implemented by software and/or hardware, and is specifically configured in an electronic device, which can be a mobile terminal or a fixed terminal.
Referring to fig. 1, a method for determining an area to which an IP address belongs according to an embodiment of the present application includes:
and S110, acquiring a target IP address.
The IP address is an address assigned to each host connected to the internet, and a user can communicate with other hosts in the internet through the host and the IP address.
The target IP address refers to an IP address to be subjected to area determination. The IP address may be an IPv4(Internet Protocol version 4) address, or an IPv6(Internet Protocol version6, Internet Protocol version 6) address, which is not specifically limited in this embodiment of the present application.
Specifically, taking the IPv4 address as an example, the IP address is 32 bits in length and is divided into 4 segments, each segment is 8 bits and is expressed by decimal numbers, the number range of each segment is 0-255, and the segments are separated by dots. For example, the destination IP address is 192.168.1.1.
And S120, converting the target IP address into an unsigned integer value by adopting a preset rule.
The preset rule is predefined and converts the target IP address to obtain an unsigned integer value which is favorable for statistics and analysis. While an unsigned integer value refers to an integer value without sign bits, which may be represented in binary, octal, decimal, or hexadecimal.
The dot data refers to each number field separated by dots in the IP address.
The two-bit hexadecimal numerical value of each point data means that hexadecimal conversion is respectively carried out on digital fields of IP addresses separated by points to obtain the two-bit hexadecimal numerical value of each point data.
The serial connection means that after points in the middle of the IP address are removed, two hexadecimal numerical values of each point data are sequentially connected from left to right to obtain an integral value of the IP address.
It can be understood that, by adopting the preset rule, the target IP address is converted to obtain the target IP address in the form of an unsigned integer value, so that the target IP address can be counted and analyzed by a numerical method.

The starting address and the ending address exist correspondingly, an IP address range is formed by the starting address and the ending address, and the IP address range represents a certain area.
The non-intersection means that for a start address and an end address indicating a certain IP address range, the network addresses (the IP addresses are composed of two parts, namely a network address and a host address) where the start address and the end address are located need to be kept consistent, that is, only if the network addresses where the start address and the end address are located are kept consistent, the start address and the end address are corresponding, and thus the indicated IP address range is correct. The network address refers to a logical address of a node on the internet in the network, the node can be addressed, and the host address refers to a part of the right part of the IP address used for identifying the host. All IP addresses in the same IP address range may be distributed in the same area, for example, belong to the same cell, the same urban area, or the same province.
The starting address integer value sequence is a starting address integer value sequence obtained by sequencing a plurality of starting address integer values; the termination address integer value sequence is a termination address integer value sequence obtained by sorting a plurality of termination address integer values. And the start address integer value in the start address integer value sequence corresponds to the end address integer value in the end address integer value sequence one to one.
Optionally, the start address integer value sequence and the end address integer value sequence may be stored in a memory after being predetermined, and may be called when needed.

By adopting the technical scheme, the effect of simply, conveniently and accurately determining the region of the IP address can be achieved.

And S240, determining the starting address and the ending address of each range.
Specifically, after at least two IP address ranges that do not intersect each other are acquired, since each IP address range has one start address and one end address, a plurality of start addresses and end addresses can be determined based on the plurality of IP address ranges.
And S250, converting the starting address and the ending address by adopting a preset rule to obtain a starting address integer value and an ending address integer value of each range.
Specifically, hexadecimal conversion is performed on the point data of the initial address to obtain two hexadecimal values of the point data; two hexadecimal numerical values of each point data are connected in series to obtain an integer value of an initial address; carrying out hexadecimal conversion on the point data of the termination address to obtain two hexadecimal values of each point data; and connecting the two hexadecimal values of each point data in series to obtain an integer value of the termination address.
It can be understood that the predetermined start address integer value and the predetermined end address integer value are the same as the rule for unsigned integer value conversion of the target IP address, so that the conversion consistency is ensured, and the accurate search of the target IP address is facilitated.
S260, sequencing the initial address integer values in all ranges from small to large to obtain an initial address integer value sequence; and sorting the termination address integer values in each range from small to large to obtain a termination address integer value sequence.
It can be understood that the starting address integer value sequence and the starting address integer value sequence are obtained by arranging the starting address integer value and the ending address integer value in an ascending order, which is beneficial to searching unsigned integer values expressed by target IP addresses in the following.
S270, loading the start address integer value sequence into a continuous memory, and loading the end address integer value sequence into the continuous memory.
The memory refers to a persistent memory for storing a start address integer value sequence and an end address integer value sequence. The memory may be a removable hard disk or an optical disk, and the embodiment of the present application is not limited thereto.
In the embodiment of the present application, the execution sequence of the above S230 to S270 and S210 to S220 is not limited, and S210 to S220 may be executed before S230 to S270, or after S230 to S270 are executed, S210 to S220 may be executed.
In an optional embodiment, assuming that the length of the start address integer value sequence and, correspondingly, the length of the end address integer value sequence are also l, the start address integer value sequence and the end address integer value sequence are respectively stored in an array, and the obtained start address array in ascending order in the unsigned integer form is recorded as asAnd the obtained ascending-order end address array in the form of unnumbered integers is marked as AeArray AsAnd AeThe length of the array is l.
Optionally, the starting address array and the ending address array are stored in the memory of the computer by means of memory mirroring. When the starting address array and the ending address array are to be read, the data can be accessed as if all the data are loaded into the memory of the computer.
In particular, a binary empty file F is createdsAdding n (the length of the array) to the file F byte by byte according to an unsigned integer memory mapping modesRemoving A, thensIt is also added to file F byte by byte in a memory mapped mannersRemoving; creating a binary empty file FeAdding n to file F byte by byte according to unsigned integer memory mapping modeeRemoving A, theneIt is also added to file F byte by byte in a memory mapped mannereAnd (4) removing.
It can be understood that the starting address array and the ending address array are stored in the memory of the computer in a memory mirror image manner, and the effect of simply and quickly accessing the starting address array and the ending address array can be achieved.

In this embodiment, before determining the region to which the target IP address belongs according to the relationship between the unsigned integer value and the predetermined start address integer value sequence and end address integer value sequence, the predetermined start address integer value sequence and end address integer value sequence need to be read from the memory. The manner of reading the predetermined start address integer value sequence and end address integer value sequence from the memory can be referred to as follows.
First, a structure (in C/C + + language) for storing a sequence of integer values is defined, and the code is as follows:
struct kb_addr{
a uint count; // uint denotes an unsigned integer type, count denotes the number of addresses
Agent _ t × saddrs; // saddrs denotes the starting address first address
}；
Wherein, uint is a pointer type pointing to an unsigned integer.
When the initial address array needs to be loaded into the memory, a structure variable for representing the initial address array is created: struct kb _ addr mykaddr _ s. To FsRead the n saved in (1) and assign it to mykaddr _ s.count; then allocating a contiguous block of memory BsTo accommodate n number of agent _ t, the first address of the block memory is saved to mykaddr _ s.saddrs; then F is mixedsCopying the content after middle n to B byte by bytesIn (1). Accordingly, a structure variable is created to represent the ending address array: structkb _ addr mykaddr _ e; to FeRead the n saved in (1) and assign it to mykaddr _ e.count; then allocating a contiguous block of memory BeTo accommodate n number of agent _ t, the first address of the block memory is saved to mykaddr _ e.saddrs; then F is mixedeCopying the content after middle n to B byte by byteeIn (1). At this point, the information needed for the query is ready. At this point, the start address integer value sequence and the end address integer value sequence required in the search are read completely.

EXAMPLE III
Fig. 3 is a flowchart of a method for determining an area to which an IP address belongs according to a third embodiment of the present application, where the present embodiment is an optimization of the foregoing scheme based on the foregoing embodiments.
Further, the operation of determining the region to which the target IP address belongs according to the relationship between the unsigned integer value and a predetermined start address integer value sequence and end address integer value sequence is refined into the operation of determining a start address integer value to be identified which is smaller than or equal to the unsigned integer value in the start address integer value sequence by adopting a dichotomy; determining an integer value of an ending address to be identified corresponding to the integer value of the starting address to be identified; and if the unsigned integer value is between the start address integer value to be identified and the end address integer value to be identified, determining that the region to which the target IP address belongs is the same as the region of the IP address range of the start address integer value to be identified. ", to complete the determination of the region to which the target IP address belongs.
Wherein explanations of the same or corresponding terms as those of the above-described embodiments are omitted.
Referring to fig. 3, the method for determining an area to which an IP address belongs according to this embodiment includes:
s310, acquiring the target IP address.
S320, converting the target IP address into an unsigned integer value by adopting a preset rule.
S330, determining the start address integer value to be identified which is smaller than or equal to the unsigned integer value in the start address integer value sequence by adopting a dichotomy.
The dichotomy is a binary search method, and can quickly search data to be searched.
Determining a start address integer value to be identified which is smaller than or equal to an unsigned integer value in a start address integer value sequence by adopting a dichotomy method means that a start address integer value closest to the unsigned integer value is found in the start address integer value sequence, and the start address integer value needs to be smaller than the unsigned integer value. That is, it is necessary that the start address integer value to be identified determined in the start address integer value sequence is the largest one of the unsigned integer values or less.
Specifically, in the process of searching the unsigned integer value by adopting the dichotomy, aiming at the initial address integer value sequence arranged in an ascending order, the address integer value recorded in the middle position of the initial address integer value sequence is compared with the searched unsigned integer value, and if the address integer value and the searched unsigned integer value are equal, the searching is successful; if not, continuing to divide and search the initial address integer value sequence; and dividing the initial address integer value sequence into a front sub-initial address integer value sequence and a rear sub-initial address integer value sequence by utilizing the middle position record, if the address integer value recorded in the middle position is smaller than the found unsigned integer value, further searching the front sub-initial address integer value sequence, and otherwise, further searching the rear sub-initial address integer value sequence. And repeating the process until the record meeting the condition is found, so that the search is successful.
S340, determining an integer value of the to-be-identified ending address corresponding to the integer value of the to-be-identified starting address.
And the integer value of the termination address to be identified corresponds to the integer value of the start address to be identified one by one. The position index of the start address integer value to be identified in the start address integer value sequence can be directly used for determining the end address integer value to be identified at the position index with the same end address integer value sequence.
And S350, if the unsigned integer value is between the start address integer value to be identified and the end address integer value to be identified, determining that the region to which the target IP address belongs is the same as the region of the IP address range of the start address integer value to be identified.
It can be understood that the unsigned integer value between the start address integer value to be identified and the end address integer value to be identified has the same network address as the start address integer value to be identified and the end address integer value to be identified, that is, the target IP address represented by the unsigned integer value is the same as the area represented by the start address integer value to be identified, and the host where the target IP address is located is only one host among the hosts in the area.
Optionally, if the unsigned integer value is not between the start address integer value to be identified and the end address integer value to be identified, determining the belonging area of the target IP address fails.
It is understood that the failure of the determination of the home region of the target IP address may be an error in the target IP address itself; alternatively, the predetermined sequence of start address integer values and the predetermined sequence of end address integer values are in error. After determining that the region to which the target IP address belongs is determined to be failed, alarming can be given to a worker, and working log recording can be carried out on the target IP address which is not successfully subjected to region determination.
Optionally, the staff checks the work log at regular time, checks the target IP address, and checks the predetermined start address integer value sequence and end address integer value sequence to determine the cause of the error, and performs corresponding adjustment.
On the basis of the embodiment, the method comprises the steps of converting a target IP address to be determined in a region to which the target IP address belongs to obtain an unsigned integer value, determining a start address integer value to be identified which is smaller than or equal to the unsigned integer value by a binary search method according to the relation between the unsigned integer value and a predetermined start address integer value sequence, determining an end address integer value to be identified according to the corresponding relation between the start address integer value to be identified and the end address integer value sequence, determining whether the unsigned integer value falls in the IP address range according to an IP address range formed by the start address integer value to be identified and the end address integer value to be identified, and if the unsigned integer value falls in the IP address range, determining the region to which the target IP address belongs to be in the IP address range; by the scheme, the effect of simply, conveniently and accurately determining the region of the IP address is achieved.
