Is your DNS round-robin setup really round?
Just test!
Take this simple script and test on your own, with python 2 or 3.
Options:
usage: dns_round_robin_test.py [-h] [-c COUNT] [-d DELAY] name positional arguments: name DNS name to test optional arguments: -h, --help show this help message and exit -c COUNT, --count COUNT set total count of resolves -d DELAY, --delay DELAY set delay between resolves in 1/100s of second
Sample run command:
$ ./dns_round_robin_test.py google.com -c 20
Sample output:
================ google.com ================ 20/20 188.43.66.170 [ ||||| 25.0%] 5 188.43.66.187 [ ||||| 25.0%] 5 188.43.66.174 [ |||||||||| 50.0%] 10

Hi!
There was no actual non-russian post till today, sorry. I’ll be a good boy 😉
I’m using Ubuntu Linux (ok, Richard, GNU/Linux) from about the end of 2006. I like it very much. I’ve tried some other distros but Ubuntu made me happy: I’ve started to work and not configure the system for myself. Ubuntu works great, looks amazing and still simple and free to get, install and use.
Since 2007 I’m working to support Russian community in many ways. Supporting http://ubuntu.ru/ is my primary role now, but I’m also looking for more opportunities to express my feelings about this great system: Ubuntu.
Hello there!
Dear visitor!
If you came to my site you probably noticed that it is in Russian. Sorry for that but I’m Russian man and I work in Russia and I speak Russian a lot. I’ve set up this English category in order to promote my international activities.
I hope, I’ll be able to write once a year at least. BTW! Feel free to subscribe to my English posts RSS feed.
