Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the accompanying claims.
As the demand for IP addresses for 5G mobile networks increases, the complexity of IP address management increases. The complexity of picking out free available IP address segments in a given mask number of bits from the IP address block is also increased by including a large number of and intermixed unused IP addresses and used IP addresses in the IP address block.
The available IP address segments free of the specified mask in the current query IP total segment can only be obtained by manually calculating all IP address segments under the specified mask bit number, screening out the used IP addresses from the IP address segments, and clustering the scattered available IP addresses to obtain the available IP address segments. Furthermore, the available IP address field needs to be verified by manually logging into the relevant network device to see if it is idle. Therefore, how to improve the efficiency and accuracy of obtaining the available IP address segments is a problem to be solved.
Aiming at the technical problems, the embodiment of the application provides a method, a device, a server and a storage medium for acquiring an available IP address field, which aim to solve the problem of improving the acquisition efficiency and accuracy of the available IP address field. The technical conception of the application is as follows: and determining a used IP address section and an unused IP address section which meet preset parameters according to the address use identification corresponding to the IP address section stored in the database, screening the IP address section containing the used IP address from the unused IP address section, and determining the usable IP address section after checking the used IP address in the routing information stored in the routing equipment.
Fig. 1 is an application scenario diagram of an available IP address segment obtaining method provided in the present application, as shown in fig. 1, including a server 10, a data server 11, a routing device 12, and a network access device 13, where the number of network access devices 13 is at least one, and in an embodiment corresponding to fig. 1, the number of network access devices 13 is 3, including a first network access device 131, a second network access device 132, and a third network access device 133. The server 10 is connected to a data server 11 for database storage, the server 10 is also connected to a routing device 12, and the routing device 12 is connected to a network access device 13 for providing services to the network access device 13. In the process of networking use of all the devices, each device uses its corresponding allocated IP address.
The data server 11 stores all the IP address segments and the related parameters of each address segment that can be allocated and utilized by the server 10, wherein the related parameters include an address usage identifier, and when the IP address segment is occupied, the address usage identifier of the IP address segment is set as a used identifier; when the IP address segment is unoccupied, the address use identifier of the IP address segment is set to be an unused identifier. When the server 10 needs to search for an unused IP address, the input unit of the server 10 obtains a preset parameter of the IP address to be searched, searches for the preset parameter from the relevant parameters of all the allocable IP address segments through the data server 11, and picks out an original target IP address segment with data corresponding to the relevant parameter equal to the preset parameter, where an address use identifier in the preset parameter of the IP address to be searched is an unused identifier, and the original target IP address segment includes an original mask bit number, and the original mask bit number in combination with the internet communication protocol version can define an address range of the target IP address segment. When the number of usage mask bits of the server 10 is higher than the number of original mask bits, a part of the IP address segments of the original target IP address segments will be used, the address usage identification of the used IP address segments is set to the used identification, but the address usage identification of the original IP target address segments remains unused, so that when determining the unused IP address, it is necessary to reject the used part of the IP address segments from the above-mentioned original target IP address segments to obtain the unoccupied IP address segments, and determine the unoccupied IP address segments as usable IP address segments.
To again confirm that the available IP address segment is unoccupied, the server 10 may obtain, through the telnet routing device 12, a routing device mapping table of the routing device 12 to obtain an IP address segment being used by the access device 13 connected to the routing device 12, and the server 10 confirms 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, determines the available IP address segment as an available IP address segment if it is unoccupied, and displays the available IP address segment so that a user using the server 10 can learn about the situation of the available IP address segment satisfying the preset parameters. Notably, when the server 10 obtains the IP address field used in the routing device table by logging on the routing device 12, the server 10 may log on at least one routing device 12, and in the embodiment corresponding to fig. 1, the number of routing devices 12 is 1, and when the number of routing devices 12 is multiple, the server 10 may confirm the use condition of the available IP address field by logging on the routing devices 12 sequentially.
Fig. 2 is a flowchart of a method for obtaining an available IP address field according to an exemplary embodiment of the present application. As shown in fig. 2, the available IP address segment acquiring method provided in the present application includes:
S201, the server acquires at least one original IP address segment, a target mask bit number and a used IP address segment.
The original IP address segment represents a usable IP address segment which is searched in a database by a server and marks that the address segment is unoccupied.
The number of bits of the target mask is the number of bits of the network address in the available IP address to be acquired by the server, the number of bits is smaller than the total number of bits of the original IP address field, and the number of address bits remaining after the number of bits of the target mask is removed in the original IP address field is the number of bits of the host address. In the original IP address segment, the address corresponding to the number of the target mask bits from left to right is a network address, and the address corresponding to the rest position after the network address is removed from the original IP address segment is a host address. For example: the number of bits of the original IP address field is 32 bits, the number of bits of the target mask is less than or equal to 32, if the number of bits of the target mask is 28 bits, the address corresponding to the first 28 bits of the original IP address field 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 that the server looks up in the database, indicating that the address field is occupied.
S202, the server obtains an original target IP address segment according to the original IP address segment and the target mask bit number.
Wherein both the original IP address field and the target mask number of bits are obtained from step S201.
The original target IP address field represents all the IP address ranges that the original IP address field can obtain under the constraint 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 for 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 AND operation, the obtained first 28-bit address of the result is the same as the first 28-bit address of the original IP address field, and the last 4-bit address is 0, and 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 and do not cross the used IP address segments from the original target IP address segments.
Wherein the original target IP address field is obtained from step S202.
The target IP address segment is an IP address segment which is smaller than or equal to a preset number threshold value and is obtained from the rest IP address segments after the server removes the used IP address segment from the original IP address segment. The target IP address segment does not cross all the used IP address segments, namely the target IP address segment does not contain the used IP address. 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 the 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 number of obtained target IP address segments is less than the preset number threshold, otherwise, the number of obtained 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, queries a target IP address segment in the routing equipment mapping table, determines the unrequired target IP address segment as an available IP address segment, and displays the available IP address segment.
The target device is a device, in at least one routing device related to the embodiment corresponding to fig. 1, to be detected whether an IP address in a routing device mapping table corresponding to the device crosses the target IP address.
The routing device mapping table represents the mapping relationship between the target device and the routing information corresponding to the device. The routing information includes an IP address in use by the network access device connected to the target device.
And querying the target IP address segment obtained in the step S203 in a routing equipment mapping table, and determining the target IP address segment which is not queried as an available IP address segment, namely determining the remaining IP addresses which are obtained after screening out the IP addresses which are not used by the network access equipment connected with the target equipment in the target IP address segment as available IP addresses, wherein the addresses are the addresses which can be allocated and used by the server.
In the technical scheme, the server determines the original target IP address segment by utilizing the obtained original IP address segment and the target mask bit number, shortens the searching range, screens the IP address segment containing the used IP address from the original target by comparing the original target IP address segment with the address coverage of the used IP address segment, determines the available IP address segment which is smaller than or equal to a preset number threshold value, verifies the availability of the available IP address segment by comparing the available IP address segment with the used IP address segment recorded in the routing mapping table of the target equipment, ensures the accuracy of calculating the available IP address segment, and improves the acquisition efficiency compared with a method for manually calculating the available IP address segment and verifying the availability of the IP address segment by one manual login equipment.
Fig. 3 is a flow chart of a method for obtaining an available IP address field according to an embodiment of the present application, where an execution body of the method is a server. As shown in fig. 3, the available IP address field obtaining method provided in the present application includes:
s301, acquiring preset parameters and an original allocated IP address field.
The preset parameters include a preset network type, a preset internet communication protocol version and a preset network allocation type.
Wherein the network type is a network type usable by the device to be allocated with the IP address, and 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 chained backup network. The internet communication protocol versions include a fourth version of the network communication protocol (Internet Protocol version, abbreviated as IPv 4) and a sixth version of the network communication protocol (Internet Protocol version, abbreviated as IPv 6), which correspond to IP addresses of different digits. The network allocation types include public networks and private networks. The above network types, internet communication protocol versions and network allocation types are all prior art and will not be explained in detail here.
S302, screening unoccupied original IP address segments from the original allocated IP address segments according to preset parameters.
Wherein the original allocated IP address field and the preset parameters are obtained from step S301.
The original allocated IP address field represents all the IP address fields that can be allocated and used by the user corresponding to the server, and the IP address field needs to store the relevant information of the IP address field into the database before being allocated and used by the user. The relevant information of the IP address field is the IP address field and the associated attribute information thereof. In one embodiment, the attribute information includes the preset parameters and address usage identification in step S301.
The unoccupied original IP address has been explained in detail in step S201, and will not be described again.
The original IP address segment represents the IP address segment with unused identification which is identified by the address found by the server in all available IP address segments stored in the database according to the preset parameters.
More specifically, the process of obtaining the unoccupied original IP address field specifically includes steps S3021 to S3024:
s3021, obtaining an address use identifier of the original allocated IP address field.
The original 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 acquisition of the address use identifier is set according to the user when assigning or using the IP address. More specifically, when an IP address segment is available but not yet used by the server, the address usage identification of the IP address segment is an unused identification; when an IP address segment is assigned by a server to a device for use, the address use identifier of the IP address segment is a used identifier.
The server queries the first IP address field satisfying the above condition in the original allocated IP address field according to the preset parameters obtained in step S301 and the address usage identifier obtained in this step. The first IP address segment is an unoccupied IP address segment with related parameters equal to preset parameters in the original allocated IP address segment.
When the server can query the first IP address field in the originally allocated IP address field, step S3022 is entered, otherwise step S3023 is entered.
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 segment is:
and determining a first IP address segment with the network type being a preset network type, the Internet communication protocol version being a preset Internet communication protocol version, the network allocation type being a preset network allocation type and the address use identification being an unused identification from the original allocation IP address segment, and determining the first IP address segment as the original IP address segment. Wherein the original allocated IP address field is obtained from step S302, the plurality of preset parameters that the first IP address field needs to satisfy are obtained from step S301, and the address usage identifier is obtained from step S3021.
After this step is completed, the flow advances to step S303.
S3023, if the first IP address field does not exist in the original allocated IP address field, determining that no IP address field is available in the original allocated IP address field, 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 original allocated IP address field, the IP address field which can be utilized by the current server does not exist, and the server generates reminding information according to the nonexistent state of the IP address field and displays the reminding information.
After the step is completed, the current flow is ended.
S303, screening out occupied used IP address segments from the original allocated IP address segments according to the preset network type.
Wherein, the preset network type is obtained from the preset parameters in step S301, and the original allocated IP address field is also obtained from step S301.
The occupied used IP address field refers to an IP address field that has been allocated by the server to be used by other devices in the callable database.
More specifically, the process of obtaining the occupied used IP address field specifically includes steps S3031 to S3034:
S3031, the address use identification of the original allocated IP address field is obtained.
The address usage identification includes a used identification and an unused identification. This step is the same as step S3021 and will not be described here again.
After obtaining the address usage identifier, the server searches for a second IP address segment which meets the requirement of the preset network type and is not used yet in the original allocated IP address segment according to the address usage identifier and the preset network type in step S303.
When there is a second IP address segment in the originally allocated IP address segment, step S3032 is entered, otherwise, step S3033 is entered.
S3032, if the second IP address segment exists in the original allocated IP address segment, the second IP address segment is screened from the original allocated IP address segment.
More specifically, a second IP address segment whose network type is a preset network type and whose address usage identification is a used identification is determined from the originally assigned IP address segments, and the second IP address segment is determined as a used IP address segment.
After the completion of this step, the flow advances to step S304.
S3033, if the second IP address segment does not exist in the original allocated IP address segment, screening a third IP address segment smaller than or equal to the preset number threshold value from the original IP address segment, 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 field does not exist, the IP address field with the network type being the preset network type in the original allocated IP address field is not used, and on the basis that the network type is the preset network type, the IP address field limited in the original IP address field according to the corresponding preset parameters is not used. Thus, in the absence of the second IP address segment, all of the original IP address segments may be assigned by the server to the device to be obtained and used.
After all the original IP address fields are determined to be available, if the number of the original IP address fields is smaller than a preset number threshold value, determining all the original IP address fields as a third IP address field; if the number of the original IP address segments is greater than or equal to the preset number threshold, selecting the IP address segments equal to the preset number threshold from the original IP address segments, and determining the IP address segments as a third IP address segment. The selection mode of the IP address field is not limited.
After the third IP address segment is selected, the server determines the third IP address segment as a target IP address segment, where the explanation of the target IP address segment is explained in detail in step S203, which is not described herein.
After this step is completed, the flow proceeds to step S306.
S304, obtaining the original target IP address segment according to the original IP address segment and the target mask bit number.
Wherein the original IP address field is obtained from step S3032, and the target mask bit number is a bit number representing the network address in the subnet mask defining the distribution range of the server lookup IP address field, and the target mask bit number is explained in detail in step S201 and is not described herein.
The process of acquiring the original target IP address segment defined by the subnet mask corresponding to the target mask bit number from the original IP address segment is explained in detail in step S202, and will not be described again here.
S305, screening out target IP address segments which are less than or equal to a preset number threshold and do not cross the used IP address segments from the original target IP address segments.
Wherein the original target IP address field is obtained from step S304.
The target IP address segment screened from the original target IP address segment means that the address distribution range of the target IP address segment does not overlap with the address distribution ranges of all the used IP address segments obtained in step S3032, i.e., the target IP address segment does not include any used IP address.
