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.
