I need some help with setting up the DNS records. This question might be already been asked, but can't find it on the forum.

When I have a existing domainname on my webserver, and I want to add (or change) an extra A record like 'test.mydomain.com' and point it outside my server (for example) to ip '12.345.67.89'.

In the control panel I add the record | test | A | 12.345.67.89.

Then when I ping test.mydomain.com the IP doesn't resolve.
After an our of 14 or what, the changes are done, and I can ping test.mydomain.com

I understand DNS update cycles, but correct me if i'm wrong, adding A records on existing domains, should be done in a span if minutes to resolve, not a day? I've seen this happening on other DA installations, but doesn't seem te work on mine?

Please advise how to speed up these changes. (I have root /admin rights if needed)
 
Prolly there would be doable with some settings in refresh ratio or something like that but i cannot say how to do that.

Im interested aswell cause i would like to understand how does service like dyndns do that so quickly :)

A fast way if you need just for test purpose is edit your hosts file

Windows:
C:\Windows\System32\drivers\etc\hosts
Linux
/etc/hosts

Well that should depend on your dns server (on your computer/connection) aswell.

I use to use google ones (8.8.8.8 and 8.8.4.4) and usually are quite fast.

PS. Thanks for the link, didnt knew that :)
 
If you change TTL now records out there still have the old TTL and won't update until those records expire.
