Customize Name Server and CDN Zone
- Your customers need to configure their website DNS setting to use the CDN service and web application firewall (WAF).
- There are two ways to configure DNS settings:
- Option A - Change the name servers of the domain to Comodo DNS servers. The domain will then use Comodo authoritative DNS.
- Option B - Create DNS 'CNAME' and 'A' records for the domain in cWatch. The admin needs to add these records to their domain's DNS management page. This means the domain will continue to use its existing authoritative DNS.
- cWatch generates 'NS', 'CNAME' and 'A' records for your customer to configure the DNS settings of their website as explained above
- Help to configure these DNS settings is available to your customers in 'CDN' > 'Settings' > 'Activation'.
- See https://help.comodo.com/topic-285-1-848-13908-Activate-CDN-for-a-Website.html in the website admin guide for more details.
- By default, cWatch provides the NS and CNAME records with 'Comodo' branding in the domain names
- You have the option to specify your own name servers, so the NS records generated for your customers do not feature Comodo branding.
- You can also specify a sub-domain for creating the CNAME record.
- You should configure the DNS settings of your name servers to point to Comodo name servers and add a new NS record for CDN subdomain generated for your customers.
