Edit DNS records

DNS records determine where your domain points: which IP address a website has, which server accepts email, which text entries serve as verification.

Where the records live

Domains → your domain → DNS → DNS records, direct address: dash.regfish.de/my/domains/<tld>/<sld>/zone/records

For each record the table shows Type, Name, Data, TTL, and an Action column with an Edit link. Above it sit the tools:

• All types filters by record type, for example MX only or TXT only.
• Columns shows and hides columns.
• Search record filters by name and data.
• New record creates a record.
• Import / Export in the top right reads in a zone file or writes the zone out as a BIND file.

At the bottom, Records per page sets how many records are shown at once.

Creating a record

1. Choose New record.

2. Set the Type. What you have to enter depends on it:

   Type	Data field	Used for
   A	IPv4 address	Web server over IPv4
   AAAA	IPv6 address	Web server over IPv6
   CNAME	Target name	Pointing to another name
   MX	Mail server + priority	Email delivery
   TXT	Free text	SPF, DKIM, DMARC, domain verification
   CAA	Flags, tag, value	Which certificate authority may issue
   ALIAS	Target name	Like CNAME, but also allowed at the domain root

3. Enter the Name. For the domain itself the domain name is enough; for a subdomain use the full name (www.example.de).

4. Set the TTL — the time in seconds that resolvers cache the response. Allowed values are 60 to 604800. Ahead of a planned change, a low value is worth setting so the change takes effect quickly.

5. Save.

Tip

Changes do not take effect everywhere at once. Resolvers hold on to the old response for as long as the previous TTL allows. So if you are planning a move, lower the TTL before you change the address, not after.

Editing and deleting

Edit in the row opens the record for editing. To delete, select the row with the checkbox on the left and confirm the deletion.

The same thing through the API

Task	Endpoint
List records	GET /dns/{domain}/rr
Create a record	POST /dns/rr
Change a record	PATCH /dns/rr/{rrid}
Delete a record	DELETE /dns/rr/{rrid}
Export the zone	GET /dns/zones/{domain}/export

The rrid is a record’s ID; it comes back in the response of GET /dns/{domain}/rr.

If you change records from a script, take a look at the DNS change with rollback recipe — it shows how to undo a change that failed.

Checking that the change has landed

The DNS Doctor tile on the domain overview checks the zone for typical mistakes. To find out whether a change is already visible worldwide, use the propagation check under Monitoring & Protection.
