Even if the IP would resolve to the server, it would not work since that subdomain is not listed in your account.
The main domain is, though as a pointer (pointer domains can not hold a subdomain on their own).
If you want to be able to add a subdomain, and host a site on it with us, you would need to add the domain as a separate domain using "Add New" under "Account Manager->Domain Setup".
Additional information:
When I checked the domain using an online tool, I got this response regarding: bajko.nz
Whois Record Not Available
This domain is not registered.
On another tool it lists as cancelled as of yesterday, did you own the domain and forget to renew it at the registrar?
