Important notes

• Changes to DNS entries take effect immediately on our nameservers, but worldwide propagation can take up to 24 hours.
• An A record and a CNAME record cannot exist simultaneously for the same hostname.
• A CNAME record can only be created for subdomains (e.g. www.example.ch), not for the main domain itself.
• If you change an MX record, please note that this affects mail delivery. Make sure the new mail server is configured correctly.

Common DNS record types

• A – Points a hostname to an IPv4 address (e.g. 185.85.110.92)
• AAAA – Points a hostname to an IPv6 address
• CNAME – Redirects a subdomain to another hostname (e.g. shop.example.ch → shopify.com)
• MX – Defines the mail server for the domain (e.g. 10 mail.example.ch)
• TXT – Text records for SPF, DKIM, DMARC, domain verifications etc.
• SRV – Defines services like Autodiscover for email clients
• CAA – Specifies which certificate authority may issue SSL certificates

Additional supported types: AFSDB, ALIAS, DNAME, DNSKEY, DS, HINFO, LOC, MINFO, NAPTR, RP, RRSIG, SPF, TLSA.

Do not delete and recreate the zone

When you create a domain in your hosting administration (Plesk), we automatically create the matching DNS zone with all the correct records for website and e-mail. You do not have to do anything.

If you delete the zone and create it again, you get an empty default zone with no connection to your hosting. The domain then points to our page «Domain not active», and the browser reports a certificate warning although the certificate is shown as valid in Plesk.

Important: If you enter the addresses of your website yourself, always adjust both records, the A record (IPv4) and the AAAA record (IPv6), each for the main domain and for www. Most visitors still come via IPv4. If only the IPv6 record is correct, most of them still see the wrong page. You find the correct addresses in your hosting administration under «Hosting & DNS» of the domain.
