DNS Delegation / Glue Records

Hi,


Can anyone assist in how this can be done. I have a domain abc.com which I have the NS records pointing at XILO for web/mail etc. I need to create xyz.abc.com that has NS records pointing at 1.1.1.1 / 2.2.2.2.


From what I understand (and have done before on another system) I need to either -


1) Host the DNS on a different system and create sub zone for xyz.abc.com with the 1.1.1.1/2.2.2.2 NS records. (Though this isnt supported by XILO/CPanel)

2) Somehow create the sub zone within CPanel to allow the delegation of the sub zone to the different name servers.


Anyone have any ideas?


Thanks,

Peter

This is possible within the portal for all gTLD domains.


Within the domain tool you can register your nameservers to point the sub-domain to the A record. It does have to follow a set format like nsX or dnsX - arbitrary names are not fully supported at this time.


DNS records also have to be created within the zone for that too so the roots and the zone itself point to the same place.


Should you have any issues in doing so, please do raise a domain support ticket via your portal.

Hi Matt,


Thanks for the reply, the problem is that I want to delegate control of the subdomain to different Name Servers (for use with dyndns etc) rather than create an A-Record that points at a specific IP.

You can create NS records in the zone that point elsewhere for that domain to be resolved by them but you wouldn't then register them as glues in that case.


Much like how DNS looks at the root domain which points nameservers to the domain, which then has nameservers for those records and you can then point sub-domains to other DNS servers.


Reseller accounts can do this out of the box via WHM but shared would need to be requested via support as cPanel does not allow creation of NS records.

Ahh, thats a shame as support said they coudln't (or wouldn't support) the creation the NS records when I'd asked. I'd hoped there was some way within CPanel I just wasn't aware of.

This has since changed a little as we've moved over our DNS backend to something in house. cPanel still works as normal and interfaces with it but allows us to do more and better site to site replication.


Pop a ticket in and we can do that for you.
