Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

The first embodiment:

referring to fig. 1, fig. 1 is a schematic flow chart of an IP address allocation method according to a first embodiment of the present invention. At present, when a cloud enterprise provides cloud server IP for a user, only two hundred or more IP addresses are often provided under a certain subnet, but with the increasing of the number of users, when the number of cloud servers to be deployed is one, two or more thousand or more in actual supply, the existing technology is difficult to meet the requirements of the user.

The inventor finds in practical work that only two hundred or more specific IP addresses can be provided under a certain subnet because when the subnet mask of the IP address of the DHCP server (Dynamic Host Configuration Protocol) is 255.255.255.0, it masks off only one byte of address parameter when providing the IP address, resulting in that the DHCP server fixes three bytes of address parameter when providing the specific IP address. For example: assuming that the address of a DHCP server is a.b.c.d, when the subnet mask of the DHCP server is 255.255.255.0, since the last address parameter D is masked by the subnet mask, the address of the DHCP server can only be a.b.c.x when providing a specific IP address to a user (where X varies from 0 to 255 and is not equal to D), and at this time, the IP address that the DHCP server can provide under a certain subnet only includes two hundred.

For the above reasons, the inventor found in practical work that when the subnet mask of the DHCP server is adjusted to 255.255.0.0, it masks off the address parameter of two bytes altogether when providing an IP address, so that the DHCP server fixes only the address parameter of two bytes when providing a specific IP address. That is, assuming that the address of one DHCP server is a.b.c.d, when the subnet mask of the DHCP server is 255.255.0.0, since the last two address parameters C and D are masked by the subnet mask, the specific IP address provided to the user can be represented as a.b.x.y (where a and B are unchanged, X ranges from 0 to 255, and Y ranges from 0 to 255), wherein the same IP address as the DHCP server cannot be included in the IP addresses obtained by the change of X and Y, that is, the IP address reserved in the protocol is discarded, and when the subnet mask is 255.255.255.0, the specific IP address that the DHCP server can provide rises from the first two hundred to six million under a certain subnet. And the reserved IP address in the protocol is the reserved IP address in the TCP/IP protocol.

Based on the above analysis, the IP address allocation method provided in the first embodiment of the present invention may be applied to a DHCP server, where the DHCP server may provide up to sixty thousand specific IP addresses under a certain target subnet, and the method may include the following steps:

s100, receiving an IP address acquisition request of a user.

In this embodiment, the user may send an IP address acquisition request to the DHCP server according to the actual needs of the user. At this time, when receiving the IP address acquisition request of the user, the DHCP server may determine whether the user is a new user or an old user according to the IP address of the user.

S200, determining a target subnet used by the user.

In this embodiment, as an implementation manner, after receiving an IP address acquisition request of a user, the DHCP server may allocate a new subnet section as a target subnet when the DHCP server determines that the user is a new subscriber according to the IP address of the user; when the DHCP server judges that the user is an old user, the IP address of the user is analyzed, the subnet of the current IP address of the user can be used as the target subnet, and a new subnet section can be allocated as the target subnet of the user according to the requirement, so as to improve the experience of the user.

As another implementation manner, in some other embodiments of the present invention, a target subnet may be determined according to the IP address providing rule of the DHCP server itself, so as to provide a specific IP address for the user.

S300, under the determined target subnet, a first IP address resource pool is obtained by determining a first address parameter and a second address parameter of the IP address under the target subnet.

In this embodiment, after obtaining a determined target subnet in step S200, all IP addresses meeting user requirements under the target subnet are obtained by determining a first address parameter and a second address parameter of an IP address under the target subnet, where the first address parameter and the second address parameter are both variable parameters. For example: when the IP address of the DHCP server is 17.102.1.1, the IP address that can be determined is in the general form of 17.102.x.y, and at least one of X and Y can be changed to obtain different IP addresses according to the change rule of the first address parameter X and the second address parameter Y, that is, when X is 1, Y can be changed from 0 to 255, and when X is 2, Y can be changed from 0 to 255. The first IP address resource pool comprises all IP addresses meeting the requirements of users.

S400, responding to the IP address acquisition request, and determining the IP address allocated to the user in the first IP address resource pool.

In this embodiment, after the IP address meeting the user requirement is obtained from the sixty-thousand IP addresses in the target subnet in step S400, and the first IP address resource pool is generated, the DHCP server responds to the IP address obtaining request of the user, and determines the IP address allocated to the user in the first IP address resource pool.

Based on the above design, in the IP address allocation method provided in the first embodiment of the present invention, when a specific IP address is provided to a user, by determining the value of the first address parameter and the value of the second address parameter in a certain target subnet, the number of IP addresses that can only be provided in a number of two hundred and more than two hundred in a certain target subnet in the prior art is increased to the number of IP addresses that can be provided in a number of sixty thousand, so that a large number of IP address acquisition requirements of the user can be met in a target subnet, and user experience is enhanced.

Because all the determined IP addresses in the determined target subnet may include some IP addresses occupied by users and some IP addresses agreed to be unusable in a protocol, an IP address meeting the user requirement is selected from all the determined IP addresses in the determined target subnet to generate a first IP address resource pool, and different policies may be set, an implementation manner provided by the embodiment of the present invention is: and eliminating IP addresses which are occupied by users and cannot be used in the protocol in all IP addresses under the target subnet, and taking the remaining IP addresses as a first IP address resource pool meeting the requirements of the users. Referring to fig. 2, fig. 2 is a schematic flow chart of the sub-steps of step S300 in fig. 1. As an implementation manner, in the present embodiment, the step S300 may include the following sub-steps:

s311, under the target subnet, all IP addresses under the target subnet are obtained through the change of at least one parameter of the first address parameter and the second address parameter.

In this embodiment, after obtaining a determined target subnet in step S200, all IP addresses in the target subnet are obtained by determining a change in at least one of the first address parameter and the second address parameter of the IP address in the target subnet.

S312, all IP addresses under the target subnet are removed from the IP addresses which cannot be used currently, and the remaining IP addresses are used as a first IP address resource pool meeting the requirements of the user.

In this embodiment, after all IP addresses in the target subnet are obtained in step S311, the IP addresses that cannot be used currently in all IP addresses in the target subnet are removed, and the remaining IP addresses are used as the first IP address resource pool meeting the user requirement, where the IP addresses that cannot be used currently include IP addresses that have been occupied by users and/or IP addresses that cannot be used in a protocol.

The manner of obtaining the IP address already occupied by the user may be, but is not limited to: when the DHCP server acquires the IP address acquisition request of the user, the DHCP server acquires the IP address allocated by the user when all the previous IP address requests according to the IP address of the user, and the IP address allocated when all the previous IP address requests is the IP address occupied by the user when the current IP address acquisition request is carried out.

Based on the above design, in the IP address allocation method provided in the first embodiment of the present invention, when a specific IP address is provided to a user, after all IP addresses of the target subnet are obtained, the IP addresses occupied by the user are removed, and the remaining IP addresses are used as the first IP address resource pool meeting the user requirements and provided to the user, so that it is ensured that the IP addresses provided to the user are available IP addresses, and the experience of the user is enhanced.

As another policy for obtaining the first IP address resource pool, another implementation manner provided in the embodiment of the present invention is: and respectively labeling the IP addresses which can be used by the user in all the IP addresses under the target subnet, the IP addresses which are occupied by the user and can not be used in the protocol by adopting different identifications. Referring to fig. 3, fig. 3 is another schematic flow chart of the sub-steps of step S300 in fig. 1. As another implementation manner, in this embodiment, step S300 may further include the following sub-steps:

s321, under the target subnet, obtaining all IP addresses under the target subnet through the change of at least one parameter of the first address parameter and the second address parameter.

S322, all IP addresses under the target subnet are used as a first IP address resource pool meeting the user requirements, wherein the IP addresses in the first IP address resource pool are respectively marked with an identifier whether the IP addresses are occupied by the user.

In this embodiment, after obtaining all the IP addresses in the target subnet through step S321, the DHCP server obtains the IP addresses allocated by the user when the user requests all the previous IP addresses according to the IP address of the user, and labels all the IP addresses in the target subnet by using different identifiers, so as to distinguish the occupied IP addresses from the unoccupied IP addresses in all the IP addresses in the target subnet.

For example, when an IP address is obtained, each IP address may be assigned with associated field information, which may be used to characterize whether the IP address is already occupied. Assigning 1 to the assigned IP address field of all previous IP address requests, and assigning 0 to the assigned IP address field of the unoccupied IP address in all IP addresses under the target subnet, so as to represent whether the specific IP address in all IP addresses under the target subnet is occupied. When the associated of the target IP address is 0, it means that the target IP address is available; when the associatedness of the target IP address is 1, it is characterized that the target IP address is occupied.

It should be noted that, in the IP address allocation method provided in the first embodiment of the present invention, all the IP addresses in the first IP address resource pool are labeled to distinguish between an IP address occupied by a user and an IP address not occupied by the user, and the labeling manner may also be: and marking the IP address occupied by the user in the first IP address resource pool and not marking the IP address not occupied by the user, or marking the IP address not occupied by the user and not marking the IP address occupied by the user, or marking by other means, as long as the occupied IP address and the unoccupied IP address in the first IP address resource pool are distinguished.

Based on the above design, in the IP address allocation method provided in the first embodiment of the present invention, when the IP address acquisition request of the user is obtained, the IP addresses already allocated to the user in the target subnet in all past IP address acquisition requests of the user are obtained at the same time, and when all the IP addresses under the target subnet are provided to the user, the IP addresses are all marked with the identifier of whether the IP addresses are already occupied by the user, so as to ensure that the user definitely determines whether the selected IP addresses are available IP addresses, thereby enhancing user experience.

After a first IP address resource pool meeting user requirements is obtained, different strategies can be set to provide the IP addresses required by the user to the user, and an implementation manner provided by the embodiment of the invention is as follows: and directly distributing the IP addresses meeting the IP address quantity required by the user by the DHCP server according to the IP address quantity required by the user. Referring to fig. 4, fig. 4 is a schematic flow chart of the sub-steps of step S400 in fig. 1. As an implementation manner, in the present embodiment, the step S400 may include the following sub-steps:

s411, obtaining the number of the IP addresses requested by the user according to the IP address obtaining request.

In this embodiment, when the DHCP server obtains the IP address obtaining request of the user and when it is indicated in the IP address obtaining request of the user that the user needs to obtain a plurality of IP addresses, the DHCP server may analyze the IP address obtaining request of the user first to obtain the number of IP addresses requested by the user.

And S412, in the first IP address resource pool, determining the IP addresses meeting the number of the IP addresses requested by the user as the IP addresses allocated to the user.

In this embodiment, after obtaining the number of IP addresses requested by the user through step S411, the DHCP server determines, in the first IP address resource pool, an IP address satisfying the number of IP addresses requested by the user as an IP address allocated to the user according to the number of IP addresses requested by the user.

The manner of determining the IP addresses satisfying the number of IP addresses requested by the user may be, but is not limited to: random generation, sequential arrangement, etc. For example: assuming that the number of the IP addresses requested by the user is 10, at this time, the DHCP server may randomly select 10 IP addresses from the first IP address resource pool to provide to the user, so as to meet the user's requirement; or after the previously allocated IP addresses are passed, according to the sequence number arrangement, 10 specific IP addresses are selected from the first IP address resource pool to be provided to the user, so as to meet the user's requirements.

Based on the above design, according to the IP address allocation method provided in the first embodiment of the present invention, when the number of IP addresses requested by the user is large, IP addresses meeting the user requirement can be allocated to the user at one time according to the predetermined allocation rule, which reduces the user request link, improves the efficiency of allocating a large number of IP addresses to the user, and enhances the user experience.

The embodiment of the invention also provides an implementation mode for determining the IP address allocated to the user, which comprises the following steps: and listing all IP addresses with the same value of the first address parameter in all the IP addresses determined under the target sub-network as the value of the first address parameter input by the user according to the first address parameter input by the user, and allocating the target IP address to the user according to the target IP address selected by the user. Referring to fig. 5, fig. 5 is another schematic flow chart of the sub-steps of step S400 in fig. 1. As another implementation manner, in this embodiment, step S400 may further include the following sub-steps:

s421, receiving the value of the first address parameter input by the user.

In this embodiment, after the DHCP server obtains all IP addresses meeting the user requirements under the target subnet according to step S300 to generate the first IP address resource pool, a value of the first address parameter input by the user may be received, so that the user may autonomously select a desired IP address.

S422, in the first IP address resource pool, according to the value of the first address parameter input by the user, all selectable IP addresses with the same first address parameter value of the IP address and the first address parameter value input by the user are searched in the first IP address resource pool.

In this embodiment, after obtaining the value of the first address parameter input by the user, according to the value of the first address parameter input by the user, the DHCP server searches all IP addresses having the same first address parameter value as the first address parameter value input by the user in the first IP address resource pool, and uses the IP addresses as selectable IP addresses, and displays all the selectable IP addresses to the user in a list form.

And S423, receiving the IP address selected by the user from the selectable IP addresses as the IP address determined to be allocated to the user.

In this embodiment, after all the selectable IP addresses determined according to the value of the first address parameter input by the user are obtained and displayed in step S422, the user may select an IP address required by the user according to all the selectable IP addresses displayed in the list, and meanwhile, after receiving an IP address selected by the user from the selectable IP addresses, the DHCP server takes the IP address as an IP address determined to be allocated to the user.

Based on the above design, in the IP address allocation method provided in the first embodiment of the present invention, after all IP addresses meeting user requirements are acquired as the first IP address resource pool in the determined target subnet, according to the value of the first address parameter input by the user, all IP addresses in the first IP address resource pool, where the value of the first address parameter is the same as the value of the first address parameter input by the user, are determined as the selectable IP addresses of the user, and the IP addresses allocated to the user are determined in a manner selected by the user, so as to enhance user experience.

Referring to fig. 6, fig. 6 is an operation diagram illustrating the IP address allocation method provided in fig. 5. In this embodiment, after the DHCP server determines a target subnet, according to the value of the first address parameter input by the user, the DHCP server lists the IP addresses whose values of the first address parameter in all the IP addresses under the target subnet are the same as the value of the first address parameter input by the user, and finally, according to the IP address selected by the user from the listed IP addresses, the IP addresses allocated to the user are determined; meanwhile, according to the method of the first IP address resource pool shown in fig. 3, among all listed IP addresses, the IP addresses already occupied by the user are labeled, and all listed IP addresses are sorted according to the available-allocated order; the allocated IP address can be set to be unselected, so that the situation that one allocated IP address is selected due to the mistaken selection of a user is avoided, and the user experience is enhanced.

The embodiment of the invention also provides an implementation mode for determining the IP address allocated to the user, which comprises the following steps: according to the value of the first address parameter and the value of the second address parameter input by the user, searching an IP address with the value of the first address parameter and the value of the second address parameter being the same as the value of the first address parameter and the value of the second address parameter input by the user in a first IP address resource pool, and determining the IP address as the IP address allocated to the user when the IP address input by the user exists in the first IP address resource pool. Referring to fig. 7, fig. 7 is another schematic flow chart of the sub-steps of step S400 in fig. 1. As another implementation manner, in this embodiment, step S400 may further include the following sub-steps:

s431, receiving the value of the first address parameter and the value of the second address parameter input by the user.

In this embodiment, after the DHCP server obtains all IP addresses meeting the user requirement under the target subnet according to step S300 to generate the first IP address resource pool, the value of the first address parameter and the value of the second address parameter input by the user may be received as the IP addresses selected by the user.

S432, searching a target IP address with the first address parameter value and the second address parameter value which are respectively the same as the first address parameter value and the second address parameter value input by the user in the first IP address resource pool.

In this embodiment, after the value of the first address parameter and the value of the second address parameter input by the user are obtained in step S431, the target IP address with the first address parameter value and the second address parameter value respectively the same as the value of the first address parameter and the value of the second address parameter input by the user may be searched in the first IP address resource pool.

S433, determining the target IP address as the IP address allocated to the user,

in this embodiment, when the IP addresses with the same value of the first address parameter and the same value of the second address parameter, which are input by the user, are found in the first IP address resource pool in step S432, the IP addresses may be determined as the target IP addresses to be allocated to the user; when the IP addresses that are the same as the value of the first address parameter and the value of the second address parameter input by the user are not found in the first IP address resource pool in step S432, an error message may be sent to the user to prompt the user that the address is occupied, and then step S431 is executed again until the IP addresses that are the same as the value of the first address parameter and the value of the second address parameter input by the user can be found in the first IP address resource pool, are used as the determined target IP addresses and are allocated to the user.

Based on the above design, in the IP address allocation method provided in the first embodiment of the present invention, after all IP addresses meeting user requirements are acquired under a determined target subnet as a first IP address resource pool, according to a value of a first address parameter and a value of a second address parameter input by a user, IP addresses that are the same as the value of the first address parameter and the value of the second address parameter input by the user are searched in the first IP address resource pool, and the IP addresses are allocated to the user as the determined target IP addresses, so as to increase user experience.

The embodiment of the invention also provides an implementation mode for determining the IP address allocated to the user, which comprises the following steps: and the IP address determined according to the value of the first address parameter and the value of the second address parameter selected by the user is used as the IP address allocated to the user. Referring to fig. 8, fig. 8 is another schematic flow chart of the sub-steps of step S400 in fig. 1. As another implementation manner, in this embodiment, step S400 may further include the following sub-steps:

s441, the first address parameter selected by the user from all the selectable first address parameters is received.

In this embodiment, after the DHCP server obtains all the IP addresses meeting the user requirement in the target subnet according to step S300 to generate the first IP address resource pool, the first address parameters of all the IP addresses meeting the user requirement in the first IP address resource pool may be sorted, listed according to a certain order and displayed to the user, as the first address parameter selectable by the user, and then the first address parameter selected by the user in all the selectable first address parameters is received, as the first address parameter selected by the user, where all the selectable first address parameters include the first address parameters of all the IP addresses meeting the user requirement in the first IP address resource pool.

S442, according to the selected first address parameter, all selectable IP addresses having the same first address parameter of the IP address as the selected first address parameter are searched in the first IP address resource pool.

In this embodiment, after the first address parameter is selected according to step S441, according to the value of the selected first address parameter, the DHCP server searches all IP addresses having the same value as the first address parameter of the IP address in the first IP address resource pool as selectable IP addresses, and displays all the selectable IP addresses to the user in the form of a list or the like.
