IP address distribution method based on area codes and data center server

Abstract

The invention provides an IP address distribution method based on area codes. The IP address distribution method is characterized by comprising the following steps that a data center server is configured and used for being connected with base stations distributed nationwide to form a wide-area Internet, unified network configuring, monitoring and managing are conducted on the base stations in the whole network through the data center server, and IP addresses are distributed on the base stations in the whole network based on the area codes. According to the IP address distribution method, the area codes are explicitly merged into the second bytes and the third bytes of the IP addresses so that the information of the city which infrastructures belongs to can be rapidly identified according to the distributed IP addresses, and the IP address distribution difficulty is lowered; meanwhile, the network prefixes of the IP addresses are the same or similar, route aggregation is facilitated, the IP address distribution difficulty under the large-scale network can be obviously lowered, and the route efficiency is improved. The invention further relates to the data center server used for IP address distribution and management.

Description

technical field [0001] The invention relates to the technical field of communication networks, in particular to an IP address allocation method based on telephone area codes and a data center server. Background technique [0002] IP (Internet Protocol) is the core protocol of the TCP / IP protocol family. The IP address is a 32-bit identifier assigned to each interface of each host (or router) in the network, and is used for network addressing. Currently, the version number of the IP protocol is 4 (abbreviated as IPv4). Due to the rapid development of the network, the entire IPv4 address space resource is very scarce. In order to solve this problem and improve the utilization rate of IP address resources, the concept of variable length subnet mask VLSM (Variable Length Subnet Mask) was first proposed, and then on the basis of VLSM, a non-classified addressing method was further studied, namely Classless Inter-Domain Routing selects CIDR (Classless Inter-Domain Routing).

Problems solved by technology

However, in a complex large-scale network, such as a nationwide infrastructure interconnection, the network usually has a wide coverage and a large number of network nodes; it is often difficult to divide the address blocks by simply changing the length of the CIDR network prefix. Moreover, because it cannot reflect the regular characteristics of the infrastructure in the region, the network planning is chaotic and the routing efficiency is low.
