Dns Monitor is very useful for network administrators, server administrators, and webmasters. It has served customers from 30 countries and big corporations such as Cisco, IBM, Motorola, and Nokia. Dns Monitor is able to do three things. Watch working states of dns servers. Dns Monitor will send messages and take necessary steps to deal with troubles within seconds when any dns servers work abnormally. Dns Monitor (registered edition) is able to watch thousands of dns servers (maximum number limited only by CPU capability), and send dns querys to all target dns servers simultaneously and receive responses without affecting each other. Analyze the quality of responses from monitored dns servers. Dns Monitor could record and display each sections of every response, which enable Users to decide whether to optimize the dns server.
