dnsperf 2.14.0-2 (arm64 binary) in ubuntu oracular

 dnsperf gathers accurate latency and throughput metrics for the Domain Name
 Service (DNS). Network operators can benchmark their naming and addressing
 infrastructure. dnsperf "self-paces" the DNS query load to simulate network
 conditions.
 .
 resperf systematically increases the query rate and monitors the response
 rate to simulate caching DNS services.
