How to use Vesta DNS service without Digital Ocean DNS Management

[lostncg]

First, I have to say sorry about my stupid, this question may similar with many post that can be googling, but I still can't understand.

My server is Digital Ocean Ubuntu 16.04,
nameserver(ns1.digitalocean.com & ns2.digitalocean.com) of DO is set in FREENOM custom nameserver
4 A records are created in DO DNS Management and point to DO VPS IP :
domain.ml XXX.XXX.XXX.XXX
ns1.domain.ml XXX.XXX.XXX.XXX
ns2.domain.ml XXX.XXX.XXX.XXX
ns3.domain.ml XXX.XXX.XXX.XXX

After the installation of Vesta control panel, I change the default nameserver in Vesta to ns1.domain.ml & ns2.domain.ml

My requirement is
without config in DO, just add subdomain in Vesta CP and make it work

But failed
Currently, I have to add subdomain.domain.ml into DO A record, then it will work

Anyone can help me?

You need to be able to create glue records for your custom nameservers. These are sometimes referred to as "vanity" or "child" nameservers, usually this can be done with your domain registrar.

For freenom, this looks like the guide you need to follow - https://my.freenom.com/knowledgebase.ph ... ticle&id=3

Once that is set up and the glue records are propagated you should be amble to use nsx.domain.ml as DNS servers that read records from your Vesta DNS settings.

EDIT: If you want to then use subdomain.domain.ml with the Vesta DNS, you will need to set separate NS records in DO, would look like this:
subdomain.domain.ml NS ns1.domain.ml
subdomain.domain.ml NS ns2.domain.ml
subdomain.domain.ml NS ns3.domain.ml
