Error when adding a new domain / Park a Domain

[itaivanx]

When I'm adding a new park domain, itaivan.com, the error say:
Unable to add the domain name − Sorry, the domain is already pointed to an IP address that does not appear to use DNS servers associated with this server. Please transfer the domain to this servers nameservers or have your administrator add one of its nameservers to /etc/ips.remotedns and make the proper A entries on that remote name server.
I can change my NS before, as I have other stuff running in that domain, as email.

All my domain are managed in the same NS Server, so I can't change that. I just would like to use my www with x10hosting.

Hi,

For security reasons, we require that any domains must point to our nameservers before they can be parked. This is to verify that you are the owner of the domain.

Our nameservers are:
ns1.x10hosting.com
ns2.x10hosting.com

Once you have parked your domain name, you can add other DNS records in the Advanced DNS Editor, if you need to.

Thank you,

I can certify to you that I own the domain just creating any txt file or any other records, as Microsoft, Google and other companies does.
Can we do that?
