Managing DNS records

This process covers creating, editing and deleting individual DNS records within an existing DNS zone.

Prerequisites

Before creating or changing a DNS record, check:

• that the correct DNS zone is selected
• which record type (e.g. A, MX, TXT) is needed
• whether the desired name is already used by another record
• whether the change affects your website, email delivery or other services

Note

Incorrect DNS records can make a domain unreachable or stop email delivery. Review changes carefully before saving.

Available record types

The following record types are available:

Type	Purpose
A	points a name to an IPv4 address
AAAA	points a name to an IPv6 address
ALIAS	points a name to another name (also possible at the zone apex @)
CNAME	points a name to another name
MX	sets the mail server responsible for receiving email
SRV	points to a service including its port
TLSA	stores a certificate fingerprint for DANE/TLSA
TXT	stores arbitrary text, e.g. for SPF or DMARC records

Step-by-step: creating a record

1. Sign in to the customer portal

Sign in with your account in the customer portal.

2. Open the zone

Navigate to DNS Zone in the main menu and open the desired zone.

3. Create a new record

Click New in the records table.

4. Enter the details

Fill in the required information:

• Type – the desired record type (see table above)
• TTL – time to live in seconds (range 0–604800, default 300)
• Name – the hostname of the record (e.g. www or @ for the domain itself)
• Content – the target value of the record (e.g. an IP address or hostname)
• Priority – required only for MX and SRV records; lower values are preferred

5. Review your input

Before saving, check in particular:

• that the selected type is correct
• that name and content are entered without errors
• that a priority is set for MX or SRV records

6. Save the record

Save the new record.

Editing an existing record

The Name, Content, TTL and Priority columns can be edited directly in the table:

1. Click into the desired field in the records table.
2. Enter the new value.
3. Confirm the input to save the change.

Alternatively, use the Edit action on the right side of the row to open the full edit form for the record.

Deleting a record

1. Find the record to delete in the records table.
2. Click Delete on the right side of the row.
3. Confirm the security prompt.

Follow-up checks

After saving, check:

• whether the record appears correctly in the table
• whether resolution via dig or nslookup returns the expected value
• whether dependent services (website, email) remain reachable

Common issues

Record cannot be saved

Possible causes:

• the name exceeds 255 characters, or the content exceeds 65,535 characters
• no priority was set for an MX or SRV record
• the TTL is outside the allowed range of 0 to 604800
• the content does not match the format expected for the type (e.g. not a valid IP address for A/AAAA)

Domain or service is unreachable after the change

Possible causes:

• an incorrect or duplicate record was created
• an existing record was accidentally overwritten or deleted
• the change has not fully propagated on the internet yet
