Those DNS are not the best ones for me. They are the default dns servers on my
I ran a script to query the DNS and collect response time on those and it was quite crappy. I'll post my method below but the average/max response per DNS where :
75.153.176.1 Average : 136.075 msec / Max: 231 msec
75.153.176.9 Average : 140.145 msec / Max: 244 msec
Then I tried with google, not much better :
8.8.8.8 Average : 136.075 msec / Max: 231 msec
8.8.4.4 Average : 135.175 msec / Max: 254 msec
So I tried with other DNS server I could find for Telus ( »
Telus FAQ »
What are the DNS addresses used by Telus? )
209.115.152.130 Average : 63.935 msec / Max: 152 msec
209.115.152.150 Average : 63.255 msec / Max: 138 msec
216.123.224.131 Average : 60.54 msec / Max: 119 msec
209.202.110.120 Average : 103.735 msec / Max: 180 msec
209.202.110.121 Average : 102.725 msec / Max: 192 msec
I know that this is somehow empiric and maybe linked to my type of connection / place (dry DSL in North Van).
For the records, here is the (quick and dirty) bash loop I used :
$ for i in {1..200};do dig $i.test.google.com @75.153.176.9;done | awk '/Query time/ {SUM+=$4;if (($4) > max) max = ($4)} END{print "Average : "SUM/200" msec / Max: " max " msec"}'
I did a flush of local cache ($ dscacheutil -flushcache ) between all tests.
Note that 207.194.28.230 and 207.102.93.157 did not respond at all.
