Hello Mohamed,

For illustration, let's call things as follows:

Description Example
Your Registrar registry.com
Your Domain example.org
You Subdomains sub1.example.org, sub2.example.org
Your new DNS Servers ns1.dns-servers.net, ns2.dns-servers.net

Scenario 1: All DNS Records at dns-servers.net

You will need to copy all the records from the Linode DNS Manager for each subdomain to dns-servers.net. Instructions for creating the subdomains at dns-servers.net will be specific to that DNS provider.

You can use the Linode DNS Manager to browse through your subdomains to determine the records, or you can use the linode-api or the linode-cli to get your records programmatically. See the Appendix A for an example of how to do this.


Scenario 2: Use dns-servers.net for example.org, Linode's DNS servers for the subdomains

At dns-servers.net you will need to create NS records for each subdomain. Instructions for how to do this at dns-servers.net would be specific to that DNS provider.

Name Server Subdomain
ns1.linode.com sub1.example.org
ns2.linode.com sub1.example.org
ns3.linode.com sub1.example.org
ns4.linode.com sub1.example.org
ns5.linode.com sub1.example.org
ns1.linode.com sub2.example.org
ns2.linode.com sub2.example.org
ns3.linode.com sub2.example.org
ns4.linode.com sub2.example.org
ns5.linode.com sub2.example.org

Note: You do not need to remove the root example.org zone from the Linode DNS Manager as it will not be referenced.


Appendix A: Downloading DNS Records from the linode-cli

Assuming you have installed the linode-cli you would use the following command to get the id for each domain:
linode-cli domains list

id domain type status soa_email
968719 example.org master active x@mail.me
1769660 sub1.example.org master active x@mail.me
818976 sub2.example.org master active x@mail.me

For each domain, using its id, you would then use the following command to get the records for that domain (sub1.example.org is shown):

linode-cli domains records-list 1769660

id type name target ttl_sec priority weight
8057428 TXT v=spf1 mx -all 0 10 5
18461244 A blog 10.105.2.127 0 0 0
19106776 A mail 10.164.221.203 0 0 0
```
