DNS “ping”

from nsping.8

 Nsping uses DNS queries to monitor reachability and operation of name-
 servers, 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.
