Problems solved by technology

[0003] However, due to the intermittent use of IP addresses (that is, IP addresses may be connected to the network at any time, they may also be offline at any time) and the continuous expansion of the network scale, making it very difficult to detect idle IP addresses

Embodiment Construction

[0045] In order to realize the purpose of the present invention, the present invention adds a functional plug-in to the network management server to realize the free detection of the allocated IP addresses in the IP address pool. The functional plug-in is specifically divided into two parts, the foreground and the background. The foreground is responsible for the start of idle IP address detection, the distribution of idle IP address detection configuration, and the query of idle IP addresses. The background is responsible for idle IP address reachability detection, The update of free IP address data and the provision of free IP address data after the administrator sends a free IP address query command through the foreground. Through the long-term effective periodic detection of IP addresses in the present invention, idle IP addresses that have not been used for a long time are recorded, so that it is convenient for administrators to release and re-allocate these idle IP addres...

Abstract

The invention provides a device for detecting idle IP addresses and a method corresponding to the device. The device for detecting the idle IP addresses comprises two parts, namely a foreground and a background, wherein the foreground is responsible for the starting of detection of the idle IP addresses and issue of configuration, and the background is responsible for accessibility detection of the IP addresses, data updating of the idle IP addresses and providing of the data of the idle IP addresses when an administrator inquires the idle IP addresses. Long-term and effective periodical detection is carried out on the IP addresses through the device and the corresponding method, the IP addresses not used for a long time are recorded, and therefore the network administrator releases and reallocates the idle IP addresses conveniently, and further the resource utilization rate of the IP addresses is improved.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method and device for detecting idle IP addresses. Background technique [0002] As a kind of network resource, IP address has been in-depth network management. Through the management of IP address, network administrators can keep abreast of the access status and utilization rate of IP addresses in the network, so as to re-plan the network. For those IP addresses that have not been used for a long time , can be released to save IP address resources. [0003] However, due to the discontinuous use of IP addresses (that is, an IP address may be connected to the network at any time, it may also be offline at any time) and the continuous expansion of the network scale makes it very difficult to detect idle IP addresses. Contents of the invention [0004] In view of this, the present invention provides a method and device for detecting idle IP addresses. Through the method of the...
