Abstract

The invention relates to the technical field of network communication, in particular to a subnetwork division method and device. The method comprises the following steps: configuring an IP network segment address of an IP address pool on a dynamic host configuration protocol (DHCP) server, a network mask of the IP address and a subnet mask of the IP address, so that the DHCP server divides the IP address pool into a plurality of subnets based on the network mask of the IP address and the subnet mask of the IP address; and configuring an IP gateway address of gateway equipment accessed to the DHCP server, a network mask of the gateway IP address and a subnet mask of the gateway IP address, so that the gateway equipment configures one gateway IP address for each subnet in the plurality of subnets.

Description

technical field [0001] The present application relates to the technical field of network communication, in particular to a subnet division method and device. Background technique [0002] IP is 32-bit binary data, usually expressed in decimal and separated by ".". IP address is a logical address, which is used to identify each host in the network. IP is unique, that is, the IP of each machine is unique in the world. The Internet is composed of many small networks, and each network has many hosts, thus forming a hierarchical structure. The hierarchical characteristics of address allocation are considered in the design of IP addresses, and each IP address is divided into two parts, the network number and the host number, so as to facilitate the addressing operation of the IP address. The network number and host number of the IP address are determined by the subnet mask. The function of the subnet mask is to divide an IP address into two parts: the network address and the hos...
