Is it possible to alias DKIM records, and what is NS delegation?

Email marketer from Web Hosting Talk mentions that NS delegation can be used for service portability. By delegating a subdomain to your own name servers, you can switch between different providers without requiring your users to change their DNS settings. This gives you more flexibility and control over your infrastructure.

Email marketer from StackExchange explains that CNAME flattening is a technique used by DNS providers to automatically resolve CNAME records to their underlying A records. This is important for certain DNS configurations, such as when a domain apex (e.g., example.com) needs to point to a service that only provides an IP address.

Email marketer from Quora explains that NS delegation helps in separating concerns and responsibilities for different parts of a domain. This allows different teams or organizations to manage their respective parts of the DNS without interfering with each other, improving overall efficiency and security.

Email marketer from Superuser answers that DKIM records can be aliased using CNAME records. Instead of directly setting the DKIM TXT record on your domain, you can create a CNAME record that points to the ESP's DKIM record. This allows the ESP to manage the DKIM key rotation and other DKIM configurations.

Marketer from Email Geeks explains that aliasing DKIM records is possible, as many ESPs built on top of cloud ESPs do this. You need to generate a sending domain per client with the selector, but point them to your DNS in your UI. SendGrid checks for the TXT and downstream records, not the CNAME. Matching the subdomains exactly is important. Also suggests NS delegation.

Email marketer from Medium states that CNAME records are used when you want a domain name to point to another domain name, rather than an IP address. This is useful when the IP address of the target domain might change, as the CNAME record will automatically update to the new IP address. A records directly map a domain name to an IP address.

Email marketer from Reddit shares that NS delegation is commonly used for handing off control of a subdomain to a third-party service, such as a hosting provider or a CDN. By delegating the subdomain, the third party can manage all DNS records for that subdomain, making integration and management easier.

Email marketer from Stack Overflow explains that NS delegation allows you to delegate a subdomain to a third-party DNS provider. This is useful when you want to give control of a portion of your domain to another entity, allowing them to manage DNS records independently.

Email marketer from DNSimple explains that an NS record delegates a domain or subdomain to a set of name servers. This delegation means the specified name servers are authoritative for that domain or subdomain, and all DNS queries will be directed to those servers.

Expert from Email Geeks warns that getting clients to actually do NS delegation can be a pain, despite it being a better approach.

Expert from Email Geeks explains that if you look up the record, it will end up at SendGrid, so it is hidden but not completely. Regarding NS Delegation NS just means your team needs to manage all the DNS records for your clients. The client sets up the NS record pointing to your DNS servers, and you manage all the DNS beyond that.

Expert from Word to the Wise explains that subdomain delegation (NS delegation) is handing off a subdomain to someone else, letting them control the DNS records on the delegated subdomain. It can be used to separate concerns and to allow other systems or people to manage the zone.

Documentation from DigitalOcean shares that NS records are used to delegate a zone (domain or subdomain) to a set of name servers. When a DNS resolver queries a domain, it uses the NS records to determine which name servers are authoritative for that domain, and thus, where to find the relevant DNS records.

Documentation from RFC Editor explains that Name Server (NS) records are used to delegate authority for a domain or subdomain to a specific set of name servers. This delegation allows for distributed management of DNS zones, where different parts of the domain can be managed by different entities.

Documentation from Google explains that to add a DKIM record, you may need to add a CNAME record provided by Google, and the CNAME record will point to Google servers to verify DKIM. It is important to check with your domain provider to ensure CNAME is allowed.

Documentation from IETF details that DKIM relies on DNS to store the public key used to verify email signatures. The DKIM record is stored as a TXT record in the DNS zone for the domain, and the receiving mail server retrieves this record to validate the DKIM signature on incoming emails.

Documentation from Cloudflare explains that DKIM records often use CNAME records to point to the ESP's servers. Cloudflare automatically flattens these CNAMEs, resolving them to the underlying A records, which is necessary for DKIM to function correctly. This ensures that the correct DKIM signature is used for email authentication.

Documentation from Amazon Web Services explains that Route 53 allows you to delegate subdomains to other DNS services. You create NS records in the parent domain's zone that point to the name servers for the delegated subdomain. This enables you to use different DNS providers for different parts of your domain.
