Welcome you are in advance of my attempt. :)

205.178.132.60 will be the master? The name does not matter to DNS, 
although it may be an issue with the service provider (Zoneedit, for 
example, wants your NS records to point to $SERVERNAME.zoneedit.com.)

Glue is only when the NS name is in your zone. You could put the NS 
records in your zone. You would then need the glue in the parent domain. 
For second-level domains this is normally done at/by the registrar, but 
in your case it would be done by those who control web-hosters.com. 
(Appears to be you.)

I get the same thing, albeit from the NS servers you mentioned.

When did you try it? Maybe NS and glue records at the parent domain 
weren't updated yet?

$ host -t ns preview.web-hosters.com.
preview.web-hosters.com name server ns4.hostingplatform.com.
preview.web-hosters.com name server ns3.hostingplatform.com.
$ host 0000025.preview.web-hosters.com.
Host 0000025.preview.web-hosters.com not found: 3(NXDOMAIN)

Summary:
     1. Must have not waited long enough for propagation of records at
        web-hosters.com NS servers.
     2. There IS no "A" record for 0000025.preview.web-hosters.com.

UPDATE:
$ host 0000025.preview.web-hosters.com. ns3.hostingplatform.com.
Using domain server:
Name: ns3.hostingplatform.com.
Address: 205.178.132.60#53
Aliases:

0000025.preview.web-hosters.com has address 205.178.132.170

One hour is an abnormally long time to cache NXDOMAIN results.
