How to redirect a subdomain to another hosting?

That is, if a record "poddomen" already exists.
If not, then it should be created and specify IP addresses that the hosting that will host poddomen.site.ru - Carli commented on July 8th 19 at 16:45

strange addition, since the creation of podelena And is created automatically. - caleb_Stehr commented on July 8th 19 at 16:48

: The question does not explicitly specify whether there is now a subdomain or not.
I assumed that he only plans to allocate a separate subdomain.
If not previously faced with such tasks, the wording "to change the a-record" can be misinterpreted.

A subdomain is an a record, it is not created by itself.
Of course, if DNS is not in control hosting services, and the user creates a subdomain, click the "create a subdomain" site, through which the panel itself creates a separate folder for a record. - Carli commented on July 8th 19 at 16:57
