Can't set PTR record for IPv6 address for Google Cloud VM

I have a Google Cloud Compute Engine VM, it has a public ipv4 IP and a public external ipv6 IP. In the console, I input the PTR record: blabla.mywebsite.com. (the domain is already verified) both for ipv4 and ipv6 in the public DNS PTR record field, and ipv4 works normally, but ipv6 will return:

Invalid value for field 'resource.name': 'External IPv6'. Access config name is immutable.

Is that mean currently I can't add ptr records for an ipv6 IP? or is there any wrong with my configuration?

Solution

  • It worked by running a gcloud command in Cloud Shell.

    gcloud compute instances update-access-config [INSTANCE_NAME] --public-ptr --ipv6-public-ptr-domain [DOMAIN_NAME]

    Although this did add an IPv6 PTR record, in the console we can't see it.

    Thanks @john-hanley for answering this.
