Is there any way to determine if my DNS provider actually use the TTL setting I provide?
$dig @ns1.google.com +nocmd gmail.com A +noall +answer
gmail.com. 300 IN A 184.108.40.206
gmail.com. 300 IN A 220.127.116.11
the second column here is the TTL value (300)
The website http://www.mxtoolbox.com/ can tell you that information.
