Nsping uses DNS queries to monitor reachability and operation of nameservers, as well as the latency of DNS queries. It does this by sending random recursive DNS queries to the nameserver (avoiding the effects of DNS caching) and measuring the amount of time between the sending of the query and the receipt of the response packet.
