DNS Lookup explanation - Neurobion - 08-15-2016 07:29 PM

Hi everyone,

I have question about how exactly is measured DNS Lookup time in your test result. I don't understand why this number is too high. I did many different tests against Goggle NS and never have so bad response query time as you.

e.g. for:

Host: edge.quantserve.com
DNS Lookup: 495 ms

I don't have higher query time than 52ms (global maximum for that host for 27040 queries)
Code:
dig @8.8.8.8 edge.quantserve.com

or

Code:
curl -w "@curl-format.txt" -o /dev/null -s edge.quantserve.com
with %{time_namelookup}

Your tests showed me 495ms, 84ms, 125ms,...

Thank you
