Create and Point a Subdomain to our system from another DNS provider without delegating our name servers using NS records
NS Records stands for nameserver records. You can add additional NS records to a domain if you plan on using another provider for some of your subdomains.
These records indicate which name servers are authoritative for the zone/domain. NS Records are primarily used if you want to break your domain into subdomains. Subdomains indicate you are delegating a portion of a domain name to a different group of name servers, thus creating NS records to point the name of the subdomain to different name servers.
1. Add your subdomain into DNSME control panel
3. Create NS records within the primary DNS provider
4. Configure Failover record for the root domain/subdomain zone
