dnstimes.sh:
-----------
... your.dns.sever domains.txt [port] - measure latency per domain, print results
... -t dtimes.txt - print average and standard deviation
for given output of previous run
... -p dtimes.txt - plot a histogram with gnuplot for it
To measure for domains relevant to you it might make sense to use something like browser bookmarks as a starting point.
In most popular browsers it is easy to extract them to .html file.
Then you could use xurls with coreutils to extract domains, e.g.
xurls < bookmarks.html | cut -d'/' -f3 | cut -d':' -f1 | sort -u | grep -F '.' > domains.txt
Now you can run dnstimes:
dnstimes.sh 192.168.1.80 domains.txt > dtimes.txt
To calculate avg and standard deviation:
dnstimes.sh -t dtimes.txt
You might also plot a histogram with gnuplot, e.g.
dnstimes.sh -p dtimes.txt
