Simple Go program to ping DNS servers.
It sends periodically DNS A requests to a resolver, for a given domain, and displays the time needed to get the reply.
First:
go get github.com/MickaelBergem/dnsping
# Provided you have configured your PATH to include $GOPATH/bin:
dnsping -helpYou should get the following output:
dnsping - monitor response time for DNS servers
Send DNS requests periodically to monitor a DNS server response time.
Usage: dnsping [option ...] targetdomain
-count=0: Number of requests to send
-d=1000: Interval to wait between two pings
-i=false: Do an iterative query instead of recursive (to stress authoritative nameservers)
-r="127.0.0.1:53": Resolver to test against
-random=false: Use random Request Identifiers for each query
-v=false: Verbose logging
