Edit DNS records at Strato

Before you start

• Any plan. Connecting a domain you own is free on every plan.
• A STRATO login and a published yaya site.

In yaya, open Website > Domain, type the name in Hostname, and click Connect domain. Keep the DNS steps open.

Sign in and find the DNS page

1. Sign in at the STRATO Kunden-Login.
2. Open Domains > Domainverwaltung.
3. Click the gear icon (Zahnrad) next to your domain.
4. Open the DNS tab.

The STRATO pages are in German. The names in this article are the ones on the screen.

What the screen calls the fields

• Präfix is the host. STRATO adds the domain name for you. Type only the front part.
• Wert is the value of a TXT record.
• For a CNAME, STRATO asks for one field. It is the target address.

Add the CNAME record for a subdomain or www

STRATO sets a CNAME on a subdomain only. Create the subdomain first if www is not in the list.

1. Open Domainverwaltung. Click Subdomains anzeigen and open the list.
2. Click the subdomain, for example www.
3. Open DNS-Verwaltung.
4. Click verwalten next to CNAME-Record.
5. Type the yaya target in the target field.
6. Tick the box next to the notice text.
7. Click Einstellungen übernehmen.

A CNAME turns off every other DNS setting on that subdomain. They come back only after you remove the CNAME.

STRATO does not say whether the CNAME target needs a final dot. Type the target as yaya shows it.

Use the bare domain

STRATO says a CNAME works for subdomains only. The bare domain keeps its own NS records. No ALIAS option is documented. Use the www plus redirect route.

Use the www fallback.

1. Connect www.example.com in yaya and add the CNAME above.
2. Open Domainverwaltung. Click the gear icon next to the bare domain.
3. Click Umleitung einrichten.
4. Choose extern and type www.example.com as the target.

STRATO lists a 301 redirect.

Test https://example.com after the change. The STRATO pages do not say that the redirect covers HTTPS. See Use a subdomain or www.

Add the TXT ownership record

yaya shows a name that starts with _cf-custom-hostname..

1. Open the DNS tab of the domain.
2. Click TXT- und CNAME-Records verwalten.
3. Click Weiteren Record erstellen.
4. Type _cf-custom-hostname.www in Präfix.
5. Paste the yaya value in Wert.
6. Click Einstellung übernehmen.

For the bare domain, type _cf-custom-hostname.

Do not change the STRATO SPF rule. It belongs to your mail.

Delete or replace a conflicting record

A name is either an alias or has other records. Remove the old record on the subdomain before you set the CNAME.

Check the result in yaya

1. Open Website > Domain.
2. Click Check again.

STRATO says changes can take up to 24 hours. yaya sets up HTTPS on its own. There is no deploy step. Leave your MX records as they are.

Fix common problems

There is no CNAME option. You are on the bare domain. Select the subdomain first.

The subdomain lost its other settings. This is normal after you set a CNAME.

Still waiting. See Fix a domain that won't verify.
