The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.
The method and apparatus for generating a virtual private cloud network subnet network address according to the present invention are described below with reference to fig. 1 to 3.
Fig. 1 is a flow chart of a method for generating a network address of a virtual private cloud network subnet, which is provided in the present invention, as shown in fig. 1, and includes:
step 110, generating a plurality of subnet network addresses of the virtual private cloud network based on the network address of the virtual private cloud network, the first length of the network identification bit in the mask of the virtual private cloud network, and the second length of the network identification bit in the subnet mask of the virtual private cloud network;
the second length is not less than the first length.
Specifically, the network address described in the embodiment of the present invention refers to an IP address, and may specifically be an IPv4 address.
It should be noted that, in the embodiment of the present invention, the mask is described by using a prefix expression method, that is, a "/" symbol and numbers from 8 to 24 are added to the IP address, where the numbers represent the length of the network identification bits in the mask. For example, an IP address field is 192.168.1.1/20, then the mask for that IP address field is "/20", which indicates that the length of the network identification bits in the mask is 20 bits.
The first length described in the embodiment of the present invention refers to the length of the network identification bit in the mask of the VPC network, and the unit is a bit.
The second length described in the embodiment of the present invention refers to the length of the network identification bit in the subnet mask of the VPC network, and the unit is a bit.
It should be noted that, in the embodiment of the present invention, when the first length ranges from 8 bits to 24 bits, it is recommended to use the network segment of the VPC network as "10.0.0.0"; when the first length ranges from 12 bits to 24 bits, it is recommended that the network segment using the VPC network is "172.16.0.0"; when the first length ranges from 16 bits to 24 bits, it is recommended that the network segment using the VPC network is "192.168.0.0".
In an embodiment of the present invention, after receiving an input from a user selecting a VPC network, the IP address of the VPC network and the first length of the network identification bit in the mask of the VPC network may be obtained. Likewise, upon receiving input from a user selecting a VPC network subnet mask, a second length of network identification bits in the subnet mask of the VPC network may be obtained.
It will be appreciated that an IPv4 address is divided by a 32-bit binary number into four digits, typically represented by 4 decimal numbers, each segment not exceeding 255 at maximum. The IP address consists of a network type, a network range, a network bit and a host bit, i.e. the IP address specifically comprises a network type segment, a network range segment, a network bit segment and a host bit segment 4-segment number. For example, the IP address is denoted as 192.168.1.1, and the values on the network type segment, the network range segment, the network bit segment, and the host bit segment in the IP address are 192, 168, 1, respectively.
The 1 st bit to 8 th bit in the 32 bit IP address is a network type segment; the 9 th bit to the 16 th bit are network range segments; the 17 th bit to the 24 th bit are network bit sections; bits 25 to 32 are the host bit segments.
Further, in an embodiment of the present invention, after obtaining the IP address of the VPC network, the first length of the network identification bit in the mask of the VPC network, and the second length of the network identification bit in the subnet mask of the VPC network, the optional values on each segment of the subnet IP address may be automatically calculated according to the IP address of the VPC network, the first length of the network identification bit in the mask of the VPC network, and the second length of the network identification bit in the subnet mask of the VPC network, so as to generate a plurality of subnet IP addresses of the VPC network, and the user may select the subnet IP address from the plurality of subnet IP addresses to create a subnet of the VPC network.
According to the virtual private cloud network subnet network address generation method, through selecting the VPC network, the mask of the VPC network and the subnet mask of the VPC network by a user, the length of the network identification bit in the mask of the VPC network and the length of the network identification bit in the subnet mask of the VPC network can be automatically calculated to generate a plurality of subnet IP addresses of the VPC network, so that the user can conveniently establish the VPC subnet by selecting the subnet IP addresses from the subnet IP addresses, the time for establishing the VPC subnet by the user is greatly saved, the accuracy of the subnet website data is ensured, the establishment flow of the VPC subnet is simplified, the establishment efficiency of the VPC subnet is improved, and the user experience is improved.
Based on the foregoing embodiments, as an optional embodiment, generating a plurality of subnet network addresses of the vpn based on the network address of the vpn, the first length of the network identification bit in the mask of the vpn, and the second length of the network identification bit in the subnet mask of the vpn, includes:
determining a first target number and a first numerical step based on the first length and the second length, if the first length is determined to be greater than the first threshold and less than or equal to the second threshold, and the second length is determined to be greater than the first threshold and less than or equal to the second threshold; the first target number is the number of network range segment values in a subnet network address of the virtual private cloud network;

The network address includes a network type segment, a network range segment, a network bit segment, and a host bit segment.
Specifically, the first threshold described in the embodiment of the present invention refers to the most significant bit in the network type segment in the IP address, that is, the first threshold may specifically take a value of 8.
The second threshold described in the embodiment of the present invention may be the highest bit in the network range segment in the IP address, that is, the second threshold may specifically be 16.
The first target number described in the embodiments of the present invention refers to the number of network range segment values in the subnet IP address of the VPC network. In the case where it is determined that the first length is greater than the first threshold and equal to or less than the second threshold, and the second length is greater than the first threshold and equal to or less than the second threshold, the first target number may be determined according to the first length and the second length.

Which is used to calculate the value of the network range segment in the subnet IP address.
It should be noted that, in the embodiment of the present invention, the specific calculation formula of the numerical step is λ=2 (8-(n％8＝＝08:n％8)) N represents a numerical parameter, which is a positive integer, which may be a second length or a second threshold. Wherein the formula term "n% 8= 08:n%8" represents: if n is divided by 8, the formula term takes the value of 8; if n is not divisible by 8, the equation term takes the remainder of n divided by 8.
Further, in the embodiment of the present invention, the first threshold may be 8, and the second threshold may be 16, which indicates that the values of the network identifier bit length in the mask of the VPC network and the network identifier bit length in the subnet mask thereof are both on the network range segment when the first length is greater than 8 and less than or equal to 16 and the second length is greater than 8 and less than or equal to 16, and only the value of the network range segment in the subnet IP address needs to be calculated, then the first target number and the first value step may be calculated based on the first length and the second length.
In the embodiment of the invention, assuming that the IP address of the VPC network is 10.0.0.1, the first length is 9 bits, the second length is 15 bits, the first target number N 1 ＝2 15-9 =64, first value step λ 1 ＝2 (8-(15％8＝＝08:15％8)) ＝2。
Further, a first data set of network range segments in the sub-network IP address is determined based on the value of the network range segments in the IP address of the VPC network, the first target number and the first value step. Specifically, the IP address of the VPC network is 10.0.0.1, then it The value of the network range segment is 0. Further, according to the calculated first target number 64 and the calculated first value step length 2, a first data set A of the network range segment in the subnet network address can be calculated 1 ＝{0,2,4,6,…,126}。
Further, a plurality of subnet network addresses for the VPC are generated based on the value of the network type segment, the value of the network bit segment, and the value of the host bit segment in the IP address of the VPC network, and the first data set of the network range segment in the subnet IP address. That is, when the IP address of the VPC network is 10.0.0.1, the value of the network type segment, the value of the network bit segment, and the value of the host bit segment in the IP address of the VPC network are 10, 0, and 1, respectively; first data set A of network range segment in subnet network address 1 = {0,2,4,6, …,126}, an IP address set consisting of a plurality of subnet IP addresses of the VPC network may be obtained, which may be denoted as 10.A 1 0.1, {10.0.0.1,10.2.0.1,10.4.0.1, …,10.126.0.1}, which contains 64 subnet IP addresses, i.e., 64 subnet IP addresses can be generated.
According to the method, when the values of the network identification bit length in the mask of the VPC network and the network identification bit length in the subnet mask are both in the network range section, the values of the network range section in the subnet IP address are calculated, so that a plurality of subnet IP addresses of the VPC network can be quickly and automatically generated for selection by a user, the time for creating the VPC subnet by the user can be saved, and the creation efficiency of the VPC subnet is improved.
Based on the foregoing embodiment, as an optional embodiment, after generating the plurality of subnet network addresses of the virtual private cloud network, the method further includes:
receiving a first input from a user, the first input for selecting a target subnet network address from a plurality of subnet network addresses;
in response to the first input, a subnetwork of the virtual private cloud network is created based on the target subnetwork network address.
Specifically, the target subnet network address described in the embodiment of the present invention refers to a subnet IP address selected by a user from a plurality of subnet IP addresses for creating a VPC subnet.
