Subdomains other IP destination

[Nowwis]

Hello,

I have a problem with a particular application.
I have a domain bbb.com
I create a subdomain a.bbb.com

I wanted to point my domain to a.bbb.com under a different ip my server.
So I went in the parent zone bbb.com order to change the ip of this subdomain. After 48h nothing worked ...

There are 24 I changed the area to tell Plesk subdomain manages its own area, and I changed all the IP for the new, but nothing happens again, I'm afraid it is not that ...

Someone could not tell me how not to do?
Or how to check whether the implementation is consistent?

Thank you in advance!

Nowwis,

are your plesk-servers also the correct dns servers?
Please be sure, that they are connected correctly.

Dear Nowwis,

you could provide me the domain via PM and I couold check it for you. It is normally an whois on the domain registry and check which nameservers are registered.
