Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
As the demand for 5G mobile network IP addresses increases, the complexity of IP address management grows. In the IP address total segment, there are a large number of unused IP addresses and used IP addresses, and the complexity of picking out a free available IP address segment with a specified number of mask bits from the IP address total segment also increases.
At present, the idle available IP address segments of the specified mask in the IP total segment can be inquired only by manually calculating all IP address segments under the specified mask bit number, and after used IP addresses are screened out from the IP address segments, the scattered available IP addresses are clustered to obtain available IP address segments. In addition, the available IP address field needs to be verified as free by manually logging into the relevant network device. Therefore, how to improve the acquisition efficiency and accuracy of the available IP address field becomes an urgent problem to be solved.
In view of the foregoing technical problems, embodiments of the present application provide a method, an apparatus, a server, and a storage medium for acquiring an available IP address segment, which aim to solve the problem of improving the acquisition efficiency and accuracy of an available IP address segment. The technical idea of the application is as follows: and determining a used IP address field and an unused IP address field which meet preset parameters according to the address use identification corresponding to the IP address field stored in the database, screening the IP address field containing the used IP address from the unused IP address field, and determining the usable IP address field after checking the used IP address in the routing information stored in the routing equipment.
Fig. 1 is an application scenario diagram of the available IP address segment obtaining method provided in this application, and as shown in fig. 1, the application scenario diagram includes a server 10, a data server 11, a routing device 12, and a network access device 13, where the number of the network access device 13 is at least one, and in the embodiment corresponding to fig. 1, the number of the network access device 13 is 3, and the network access device includes a first network access device 131, a second network access device 132, and a third network access device 133. The server 10 is connected with a data server 11 for storing the database, the server 10 is further connected with a routing device 12, and the routing device 12 is connected with a network access device 13 for providing services for the network access device 13. In the process of using all the devices in a networking mode, each device uses the corresponding and allocated IP address.
The data server 11 stores all IP address segments that can be allocated and utilized by the server 10 and related parameters of each address segment, wherein the related parameters include an address use identifier, and when an IP address segment is occupied, the address use identifier of the IP address segment is set as a used identifier; when the IP address field is not occupied, the address use identification of the IP address field is set as the unused identification. When the server 10 needs to search an unused IP address, the input unit of the server 10 obtains preset parameters of the IP address to be searched, searches the preset parameters in the relevant parameters of all the assignable IP address segments through the data server 11, and selects an original target IP address segment whose data corresponding to the relevant parameters is equal to the preset parameters, where an address use identifier in the preset parameters of the IP address to be searched is an unused identifier, the original target IP address segment includes an original mask bit number, and the original mask bit number, in combination with an internet communication protocol version, can define an address range of the target IP address segment. When the number of used mask bits of the server 10 is higher than the number of original mask bits, a part of IP address fields in the original target IP address field will be used, and the address use identifiers of the used IP address fields are set as used identifiers, but the address use identifiers of the original IP target address fields still remain unused identifiers, so when determining an unused IP address, the used part of IP address fields need to be removed from the original target IP address field to obtain unoccupied IP address fields, and the unoccupied IP address fields need to be determined as usable IP address fields.
In order to confirm that the available IP address segment is not occupied again, the server 10 may obtain a routing device mapping table of the routing device 12 by logging in the routing device 12 remotely to obtain an IP address segment being used by the access device 13 connected to the routing device 12, and the server 10 may confirm whether the available IP address segment is occupied by comparing the available IP address segment with the IP address segment in the routing device mapping table, and in the case of not being occupied, determine the available IP address segment as an available IP address segment and display the available IP address segment, so that a user using the server 10 can know about the available IP address segment satisfying preset parameters. It should be noted that when the server 10 obtains the IP address field used in the routing device table by logging in the routing device 12, there is at least one routing device 12 that the server 10 can log in, the number of the routing devices 12 in the embodiment corresponding to fig. 1 is 1, and when there are a plurality of routing devices 12, the server 10 can sequentially log in the plurality of routing devices 12 to confirm the usage of the available IP address field.
Fig. 2 is a flowchart illustrating a method for acquiring an available IP address field according to an exemplary embodiment of the present application. As shown in fig. 2, the method for acquiring an available IP address field provided by the present application includes:
s201, the server acquires at least one original IP address field, a target mask bit number and a used IP address field.
The original IP address field represents a usable IP address field that the server looks up in the database, indicating that the address field is unoccupied.
The target mask bit number is the bit number of the network address in the available IP address to be acquired by the server, the bit number is smaller than the total bit number of the original IP address segment, and the residual address bit number after the target mask bit number is removed from the original IP address segment is the host address bit number. In the original IP address segment, the address corresponding to the target mask number from left to right is a network address, and the address corresponding to the rest position of the original IP address segment after the network address is removed is a host address. For example: if the bit number of the original IP address segment is 32 bits, the target mask bit number is less than or equal to 32, if the target mask bit number is 28 bits, the address corresponding to the first 28 bits of the original IP address segment is a network address, and the address corresponding to the last 4 bits is a host address.
The used IP address field is a usable IP address field which is searched in a database by the server and marks that the address field is occupied.
S202, the server obtains an original target IP address field according to the original IP address field and the target mask bit number.
Wherein, the original IP address segment and the target mask bit number are both obtained from step S201.
The original target IP address field represents all IP address ranges available to the original IP address field under the restriction of the target mask bit number. More specifically, the original target IP address field is an IP address field obtained after performing an and operation on the subnet mask determined by the original IP address field and the target mask bit number. For example: the original IP address field is a 32-bit IP address field, the target mask bit number is 28 bits, the subnet mask corresponding to the target mask bit number is a 32-bit subnet mask with the first 28 bits being 1 and the last 4 bits being 0, after the subnet mask and the 32-bit original IP address field are subjected to the AND operation, the first 28-bit address of the obtained result is the same as the first 28-bit address of the original IP address field, the last 4-bit address is 0, in the original target IP address field corresponding to the result, the first 28-bit address is the first 28-bit address of the original IP address field, and the change range of the last 4-bit address is ' 0000 ' -1111 '.
S203, the server screens out target IP address segments which are less than or equal to a preset number threshold value and do not intersect with used IP address segments from the original target IP address segments.
Wherein the original destination IP address field is obtained from step S202.
The target IP address field is an IP address field which is obtained by the server in the original IP address field except the IP address field used and is less than or equal to the preset number threshold. The target IP address field does not have a cross phenomenon with all the used IP address fields, namely, the target IP address field does not contain the IP address marked as used. Wherein the preset number threshold represents a maximum number of IP address segments obtained in the original target IP address segment.
More specifically, when the number of original target IP address segments is less than a preset number threshold or the number of original target IP address segments is greater than the preset number threshold but the number of all target IP address segments determined from the original target IP address segments is less than the preset number threshold, the obtained number of target IP address segments is less than the preset number threshold, otherwise, the obtained number of target IP address segments is equal to the preset number threshold.
S204, the server acquires a routing equipment mapping table corresponding to the target equipment, inquires a target IP address field in the routing equipment mapping table, determines the target IP address field which is not inquired as an available IP address field, and displays the available IP address field.
The target device is a device that is related in the embodiment corresponding to fig. 1 and that determines whether an IP address in a routing device mapping table corresponding to the device to be detected is intersected with the target IP address.
The routing device mapping table indicates a mapping relationship between the target device and the routing information corresponding to the device. The routing information includes an IP address used by a network access device connected to the target device.
The destination IP address field obtained in step S203 is queried in the routing device mapping table, and the destination IP address field that is not queried is determined as an available IP address field, that is, the remaining IP addresses that are not used by the network access device connected to the destination device in the destination IP address field are screened out are determined as available IP addresses, and the addresses are addresses that can be allocated and used by the server.
In the technical scheme, the server determines an original target IP address segment by using the obtained original IP address segment and the target mask digit, reduces the search range, then screens out the IP address segment containing the used IP address from the original target by comparing the address coverage range of the original target IP address segment and the used IP address segment, determines the available IP address segments smaller than or equal to the preset number threshold, and verifies the availability of the available IP address segments by comparing the used IP address segments recorded in the routing mapping table of the available IP address segments and the target equipment, thereby ensuring the accuracy of calculating the available IP address segments, and improving the acquisition efficiency compared with a method for manually calculating the available IP address segments and verifying the availability of the IP address segments by manually logging in equipment one by one.
Fig. 3 is a flowchart illustrating a method for acquiring an available IP address field according to an embodiment of the present application, where an execution subject of the method is a server. As shown in fig. 3, the method for acquiring an available IP address field provided by the present application includes:
s301, acquiring preset parameters and an original distributed IP address field.
The preset parameters comprise a preset network type, a preset internet communication protocol version and a preset network distribution type.
In an embodiment, the network type includes a 4G signaling network, a 4G wireless network, an internet interface network, a 3G data interface network, a packet signaling service network, a voice signaling network, and a voice chain backup network. The Internet communication Protocol versions comprise a fourth version of network communication Protocol (Internet Protocol version 4, IPv4 for short) and a sixth version of network communication Protocol (Internet Protocol version 6, IPv6 for short), and the Protocol versions correspond to IP addresses with different bit numbers. The network allocation types include public networks and private networks. The above-mentioned network type, internet communication protocol version and network allocation type are all prior art and will not be explained in detail here.
S302, according to preset parameters, an unoccupied original IP address field is screened out from the original allocated IP address field.
Wherein the originally assigned IP address field and the preset parameters are obtained from step S301.
The originally allocated IP address field indicates all IP address fields that can be allocated and used by the user corresponding to the server, and the relevant information of the IP address field needs to be stored in the database before the IP address field is allocated and used by the user. The related information of the IP address field is the IP address field and the related attribute information thereof. In one embodiment, the attribute information includes the preset parameter and the address use identifier in step S301.
The unoccupied original IP address has been explained in detail in step S201, and will not be described in detail here.
The original IP address field represents an IP address field of which the address identifier found by the server in all usable IP address fields stored in the database according to the preset parameters is an unused identifier.
More specifically, the process of obtaining an unoccupied original IP address segment specifically includes steps S3021 to S3024:
s3021, obtaining the address use identifier of the original allocated IP address field.
The originally assigned IP address field of this step is obtained from step S301. The address use identifier includes a used identifier and an unused identifier, and the address use identifier is acquired according to the setting of the user when the IP address is allocated or used. More specifically, when an IP address field is available but not yet used by the server, the address use identification of the IP address field is an unused identification; when the IP address field is allocated to a certain device by the server for use, the address use identifier of the IP address field is the used identifier.
The server queries the first IP address segment satisfying the above condition from the originally assigned IP address segment according to the preset parameters obtained in step S301 and the address use identifier obtained in this step. The first IP address field is an IP address field which is originally distributed, and relevant parameters are equal to preset parameters and are not occupied.
When the server can inquire the first IP address field in the original distribution IP address field, step S3022 is proceeded with, otherwise, step S3023 is proceeded with.
S3022, if the first IP address field exists in the original allocated IP address field, screening the first IP address field from the original allocated IP address field.
More specifically, the process of screening out the first IP address field is:
and determining a first IP address field with the network type as a preset network type, the Internet communication protocol version as a preset Internet communication protocol version, the network allocation type as a preset network allocation type and the address use identifier as an unused identifier from the originally allocated IP address field, and determining the first IP address field as the original IP address field. Wherein the originally allocated IP address field is obtained from step S302, a plurality of preset parameters that the first IP address field needs to satisfy are obtained from step S301, and the address usage identification is obtained from step S3021.
After this step is completed, the process proceeds to step S303.
And S3023, if the first IP address segment does not exist in the originally allocated IP address segment, determining that no available IP address segment exists in the originally allocated IP address segment, generating reminding information, and controlling the reminding information to be displayed.
When the preset parameters are required to be met and the unoccupied IP address field does not exist, the server cannot obtain the first IP address field from the originally allocated IP address field, the IP address field which can be utilized by the current server does not exist, and the server generates the reminding information according to the state that the IP address field does not exist and displays the reminding information.
After this step is completed, the current flow is ended.
S303, according to the preset network type, the occupied used IP address field is screened out from the original IP address field.
Wherein the preset network type is obtained from the preset parameters in step S301, and the originally assigned IP address field is also obtained from step S301.
The used IP address field that is already occupied refers to an IP address field that has already been assigned by the server to be used by other devices in the database that can be invoked.
More specifically, the process of obtaining the occupied used IP address segment specifically includes steps S3031 to S3034:
s3031, obtaining the address use identification of the original distribution IP address field.
The address use identifier includes a used identifier and an unused identifier. This step is the same as step S3021, and is not described here again.
After obtaining the address use identifier, the server searches a second unused IP address field meeting the requirement of the preset network type in the originally allocated IP address field according to the address use identifier and the preset network type in step S303.
And when the second IP address field exists in the original allocated IP address field, the step S3032 is carried out, otherwise, the step S3033 is carried out.
S3032, if the second IP address segment exists in the original distribution IP address segment, screening the second IP address segment from the original distribution IP address segment.
More specifically, a second IP address segment in which the network type is the preset network type and the address use identifier is the used identifier is determined from the originally allocated IP address segment, and the second IP address segment is determined as the used IP address segment.
After this step is completed, the process proceeds to step S304.
S3033, if the second IP address segment does not exist in the original distributed IP address segments, screening a third IP address segment which is less than or equal to a preset number threshold value from the original IP address segments, determining the third IP address segment as a target IP address segment, and controlling the target IP address segment to display.
Wherein the originally assigned IP address field is obtained from step S301. The original IP address field is obtained from step S302.
If the second IP address segment does not exist, the IP address segment with the network type being the preset network type in the originally distributed IP address segment is not used, and the IP address segment which is limited in the original IP address segment according to the corresponding preset parameters is not used on the basis that the network type is the preset network type. Therefore, in the case where the second IP address segment does not exist, all the original IP address segments can be assigned to the device to acquire an IP address by the server and used.
