Question : Set up separate nameservers for a subdomain.

If we currently have a domain, let's say acme.com hosted on our current hosting provider (Hostgator), how can we set different nameservers for a subdomain of acme.com?  For example, if webdevelopment.acme.com was hosted on another server and that server requires webdevelopment.acme.com to point to another nameserver rather than just an A record.  How would I go about doing this?

Thank you

Answer : Set up separate nameservers for a subdomain.

It depends on the platform you're working with really.

What you describe is a delegation, which normally consists of these records:

# acme.com zone

webdevelopment   IN NS   ns1.webdevelopment.acme.com.
ns1.webdevelopment.acme.com.  IN A  IPAddress

Where the first record, the NS record, delegates responsibility for webdevelopment to a server called "ns1.webdevelopment.acme.com" and the second record provides glue to prevent circular lookups.

Once that's done, all records for webdevelopment would be created on the new ns1 server rather than on the name server for acme.com.
