Create a DNS Record

Similar to creating a DNS zone, you need to provide the UUID of the DNS zone to host the new record.

Note: There are various record types for DNS records, and each of them has unique specifications.

Prerequisite: You need an IONOS Cloud account with API credentials configured with the appropriate permissions.

To create a DNS zone of Type A, follow this step:

• Perform a POST request with these details:

  • corresponding UUID of the DNS zone,

  • name of the subdomain; example: www

  • record type; in this case: A,

  • content or destination of the A record in the form of an IPv4 address; example: 1.1.1.1

  • TTL you need (minimum 60 seconds and maximum 86.400 seconds), and

  • status of the DNS record (enable), true or false.

Result: On a successful POST request, you receive a response with the DNS record having the UUID assigned.

Info: If you want to create a Wildcard DNS record, you need to provide “*” as the name of your DNS record to match the requests for all non-existent names under your DNS zone name.

Request

curl --location \

Create records of other types

Cloud DNS supports the following record types: A, AAAA , CNAME, ALIAS, MX, NS, SOA, SRV, TXT, CAA, SSHFP, TLSA, SMIMEA, DS, HTTPS, SVCB, OPENPGPKEY, CERT, URI, RP and LOC.

Here is a brief explanation of the most common record types:

• A: Specifies the IPv4 address associated with a zone name.

• AAAA: Specifies the IPv6 address associated with a zone name.

• MX: Specifies the mail exchange servers for a zone name.

• CNAME: Specifies an alias for a zone name, allowing multiple names to resolve to the same IP address.

• TXT: Allows arbitrary text to be associated with a zone name that is commonly used for SPF records and other types of verification.

• NS: Specifies the name servers for a zone name.

• SRV: Specifies the location of services for a zone name that is commonly used for Session Initiation Protocol (SIP) and other protocols.

Here you can see examples of records with different record types:

Record Type	Record Name	Record Value	Notes
A	example.com	192.168.1.1
AAAA	example.com	2001:0db8:85a3:0000:0000:8a2e:0370:7334
MX	example.com	mail.example.com	Priority is mandatory
CNAME	www.example.com	example.com
TXT	example.com	v=spf1 mx -all
NS	example.com	ns1.example.com
SRV	_sip._tcp.example.com	10 5060 sipserver.example.com	Priority weight port is mandatory

Quota

To retrieve the quota of DNS records, perform a GET request to the /quota endpoint.

Result: On a successful GET request, you receive a response containing the quota limits and quota usage for your contract.

Request

curl --location 'https://dns.de-fra.ionos.com/quota' \
--header 'Authorization: Bearer eyJ0eXAiOiJKV1QiLCJraWQiO' \
--header 'Content-Type: application/json'
