Method and apparatus for monitoring IP address state

Abstract

The invention discloses a method and apparatus for monitoring an IP address state. The method comprises the following steps that: when a routing table of a certain router device in a network is updated, the router device is accessed and IP address information in the routing table of the router device is collected; IP addresses in the routing table are stored into a database and initial state information of each IP address is marked as an active state; and periodic detection is carried out on the stored IP address in the database and state information of the corresponding IP addresses is updated based on the detection results. When the routing table of the router device in the network is updated, the router device is accessed and the IP address information in the routing table is collected; and all the IP address that once occurred in the routing table can be collected, so that data loss can be avoided; and because periodic detection is carried out on the stored IP address in the database and whether the IP addresses are in active states is checked and the state information is updated based on the detection results, so that real-time monitoring of the IP address states can be realized.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a method and device for monitoring the state of an IP address. Background technique [0002] In computer network applications, each network user must have at least one IP address. IP address resources are limited. Network administrators need to know whether the IP address under management is online for a long time, whether the IP address under management is in use or not. It has been offline. The current method of managing IP addresses is usually for the network administrator to manually record the IP address and the corresponding status information into the document. It is impossible to know the usage of the IP address being managed at a certain moment. Facing the intricate network environment, how to quickly collect IP addresses and their status information, and ensure that the collected information is accurate, and realize real-time monitoring of IP address status i...
