Custom DNS NS Record
-
Hello, how can I add a custom DNS NS Record delegating a subdomain to my internal name server?

Hey there astawkieliszek!
There’s a map a subdomain section in the support pages. This should be able to guide you in completing this.

Thanks for your response!
Unfortunately, the ‘map a subdomain’ section does not cover the thing I am asking help with. I need to simply add a new NS record to my domain managed by wordpress.com (e.g. sub.example.com NS record delegating this subdomain to ns1.sub.example.com, where example.com domain is managed by wordpress.com).
The tutorial ‘Mapping Your Domain and Managing DNS’ says “There are a few kinds of DNS changes that you cannot make directly through our tools, but that can be requested by contacting us via a ticket”. “Managing NS records for a domain” is mentioned.
How can I contact worpdress.com team via a ticket? Is the forum only way to request support? I guess that adding NS records would be a very simple task, however I am not able to do this using administrative tools and I am somehow frustrated because we need it for our internal company network.

Hi there,
What exactly are you trying to do? You don’t own any custom domains on WordPress.com, so there is nowhere for you to configure name server records or any other DNS records with us.
What is the domain, and where are you trying to point it?
-
Thank you for your response!
The blog I need help with is astalabs.wordpress.com and the domain managed by wordpress.com is astalabs.com. I need a DNS NS record internal.astalabs.com that points to ns.internal.astalabs.com.

astalabs.wordpress.com is a subdomain of WordPress.com. You cannot configure ANY DNS records on that subdomain as you don’t own the root domain. We do.
If you want to have astalabs.wordpress.com appear at your own domain, internal.astalabs.com, you don’t need name servers. You need to add a CNAME record on your domain astalabs.com for the subdomain internal, pointing to astalabs.wordpress.com This must be done at your domain provider for that domain.
Next you need to add the domain mapping upgrade to your site here on WordPress.com to create a connection from this side.

We are the owner of the astalabs.com domain. We have registered this domain through WordPress.com and we can manage this domain records with your Domain Management tools. However, we cannot add NS records.
We have an internal network that is accessed through VPN connections. Its FQDN name is internal.astalabs.com. When a user query the DNS with e.g. host1.internal.astalabs.com, the DNS returns an address of wordpress server because there is a wildcard CNAME record *.astalabs.com (we cannot change it). So we have to add a NS record internal.astalabs.com that points to our internal server ns.internal.astalabs.com. Using your Domain Management tools I can add a glue A record for ns.internal.astalabs.com, so it would not be a problem, but as I mention we cannot add a NS record using your tools, that is why I am asking for your help.

We have registered this domain through WordPress.com
astalabs.com is not registered with us. It is only mapped here, and is owned by the username, astalabs, and I can only make changes to the domain mapping upgrade if requested by that user.
The domain itself is registered with Key-Systems GmbH:
https://whois.icann.org/en/lookup?name=astalabs.com
However, we cannot add NS records.
That is correct. Name server records need to be configured at your domain registrar. Currently you have that domain pointed to WordPress.com’s name servers. That is required for the mapping to work. If you add additional name servers to the domain at your registrar, the mapping upgrade you added with us might no longer work.
It’s not possible to add additional NS records directly to the DNS section here on WordPress.com.
-
What you can do is to move your domain’s DNS to a different provider that does allow DNS editing. There are free DNS hosting providers available, if you can’t do this directly with your registrar. I’m not familiar enough with them to recommend one, though.
Then you can map your domain to us using A-records instead.
You will need to add two A-records with these IPs:
192.0.78.24
192.0.78.25
That will have the same effect in pointing your domain here, but we won’t be in control of your DNS so any DNS changes will need to be made wherever you’re hosting the DNS.
-
Thank you for your answer. So I understand that one cannot add a NS record to a DNS section in worpdress.com in order to delegate subdomain to a name server. In that case we will consider moving a domain’s DNS to a different provider.
-
I have one more question. Is it possible to delete wildcard cname record *.astalabs.com from our mappings? That could resolve our problems and our worpdress page will still be accessible.
-
The wildcard CNAME cannot be deleted, no. This is a system setting for all WordPress.com sites and cannot be changed on a per-site level.
