Public parsing is not just a matter of within 10 minutes, actually also in less than a few minutes, this all not?

at least 10 minutes? Is there a way to take effect immediately? I this application is in the automatic program implementation, May 1 hour in a resolution, then every 10 minutes of 60 minutes there will be a delay, is not very friendly,

Public DNS domain name management notification to the global DNS server it can guarantee 24 hours notice to all domestic much faster

Unless you can build the DNS server
And let the end of the running program must use your own DNS server

1 hour in a parse???
This extreme
As moved a secondary finish all move on day 2 to 1 week
Now you move every day!!!!!!!!!!!!

If this is another kind of the attack on the DNS server?

then just skip the domain name, use IP directly,

Depends on the record of TTL value, many DNS service providers limit the minimum 10 minutes,
In addition, the influence of the TTL value is "cache" time, so the new analytical records can be effective immediately; On the interpretation of the original record is modified, the new value need TTL unused to take effect,
More curious is IP is changing in your scene? Normal, if is a fixed IP, you didn't modify the IP address of the DNS records, no matter what time, regardless of whether the cache, the results should be unique,
If your IP is not fixed, so there is a better way:
Looking for a fixed IP server, write a web service, an interface designed to accept a request from the real server, and then save the latest IP address, another interface for reading, return the IP address of the latest; Your real server every minute call this interface automatically report,
