Manage domains

You can distribute content through the default domain and through a personal domain.

Default domain

When creating a CDN resource, a default domain of the form *.selcdn.net is automatically generated.

You can view the default domain in the Control Panel: from the top menu, click Products → CDN → CDN Resources → CDN Resource page → General tab.

It is not recommended to distribute content directly through the default domain, as the use of third-party domains can make it difficult to promote the site and affect the order in the search engine.

Through the default domain, content is distributed via HTTPS and a Let's Encrypt® certificate is automatically issued for the domain.

Personal domain

Only a third-level subdomain for the main domain may be used as a personal domain, e.g. cdn.example.com for example.com. It is not allowed to use the main domain as a personal domain.

A CNAME record will be used to forward requests to the default domain.

By default, each CDN resource has a limit of 10 personal domains. To increase this limit for free, create a ticket.

Connect personalized domain

If you don't already have a domain you want to use as a personal domain, register it in your DNS hosting control panel.
In your DNS hosting control panel, create a resource record:
- record type is CNAME;
- record name is a subdomain of the form cdn.example.com;
- value - default domain of the form *.selcdn.net. Specify the domain without the protocol. You can view the default domain in the control panel: in the top menu, click Products → CDN → CDN Resources → CDN Resources section → Resource page → General tab.
In the Control Panel, on the top menu, click Products and select CDN.
Open the CDN resource page → General tab.
In the Personal Domains block, click Add Domain.
Specify the personal domain for which you configured the record. If you need to attach multiple domains, add them in one window, as each domain operation results in the reissuance of Let's Encrypt® CDN resource certificate.
Click Connect.
