How do I use the Linode API to set my Reverse DNS (rDNS)?

In order to assign rDNS for an IP address, you must make sure that the name you intend to use resolves to the IP address.

Getting Familiar with v4 of the Linode API

You can review the following guide:

• https://www.linode.com/docs/platform/api/getting-started-with-the-linode-api/

Once you have an access token as described in the above guide you can then get the information needed to build your request to set reverse DNS. Documentation can be found here

Using the API to set the rDNS of your IPv6 address

You will need to replace three pieces of information in the example below:

• $IPV6_ADDRESS
• $DNS_NAME
• $TOKEN (Your Access Token having read_write access to ips)

curl -H "Content-Type: application/json" \
    -H "Authorization: Bearer $TOKEN \
    -X PUT -d '{
      "rdns": "$DNS_NAME"
    }' \
