Embodiment Construction

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0056] The embodiment of the present invention discloses a method for dividing network address segments, see figure 1 As shown, the method includes:

[0057] Step S11: receiving the IP address, mask, number of divided subnets and required IP numbers corresponding to each subnet input by the user.

[0058] For example, if the user enters an IP address of 202.12.3.0, a mask of / 24, and the number of divided subnets is 5, the number of IPs required for the first...

Abstract

The present application discloses a method and system for dividing a network address segment, including: receiving an IP address, a mask, the number of divided subnets, and the required IP number of the subnet entered by a user; and obtaining the subnet by using the required IP number of the subnet The actual number of required IPs; calculate the M that is greater than or equal to the smallest 2 of the actual required IPs of the subnet [i] The even number to the power, get the assigned IP number of the subnet; use the total number of bits of the mask and the M of the subnet [i] , get the subnet mask length and subnet mask; according to the actual required IP number of the subnet from large to small, generate the order of the subnet; use the starting IP and the allocated IP number of the subnet to calculate the current subnet The broadcast address of the network; use the broadcast address and IP address of the subnet to calculate the start address of the subnet. This application only needs the user to input the IP address, mask, the number of subnets and the required IP number of the subnet, and then the network segment address and subnet mask of the subnet can be calculated, so that the network address can be quickly, accurately and automatically completed. Non-uniform division of segments.

Description

technical field [0001] The invention relates to the Internet field, in particular to a method and system for dividing network address segments. Background technique [0002] In today's society where communication is more and more developed, network construction is becoming faster and faster, and network address planning is also an indispensable part of network construction design, and automatic network address planning can reduce network planning and construction. Time and accuracy. Generally speaking, the early network address planning is generally based on manual calculations. Network engineers calculate the optimal address allocation scheme according to actual needs. However, as the network scale increases, the amount of calculation required is getting bigger. [0003] Algorithms and software in the prior art can only perform uniform subnet division, but cannot perform non-uniform subnet division. [0004] Therefore, how to quickly and accurately perform non-uniform sub...
