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 . All actions of querying and receiving are carried out simultaneously , which is much better than traditional in-turns method which usually result in long interval-time when watching too many dns servers , such as nslookup.
Each watching job is displayed in graphs : max/min/avg, TTL, lost rate etc.
