# SSL Issurance when using external DNS

If you're using an external DNS provider for your domain, you need to ensure that the DNS is set up to be able for our platform to issue SSL certificates for your domain.

## Domains added after May 12th, 2026

We use a deterministic `_acme-challenge` subdomain for each domain to issue SSL certificates.

If your domain is for example `example.com`, you need to add the following DNS records to your domain's DNS settings:

| Type    | Name                          | Value                           |
| ------- | ----------------------------- | ------------------------------- |
| `CNAME` | `_acme-challenge.example.com` | `example.com.acme-challenge.dk` |

## Domains added before May 12th, 2026

If you've added a domain before May 12th, 2026, then the DNS record you have to add can be found in the domain's DNS settings in the hosting panel.
This domain consist of a CNAME that points to a hash under the `auth.acme-challenge.dk` subdomain.

For example:

| Type    | Name                          | Value                                                         |
| ------- | ----------------------------- | ------------------------------------------------------------- |
| `CNAME` | `_acme-challenge.example.com` | `efcb7ff6-357c-49d2-ae53-d54ce73b0de7.auth.acme-challenge.dk` |
