The examples are showing an Ipv4 in the "ipAddress" field but the value of "ipAddressType" is "IP_V6". Simply changing the latter value should resolve this mismatch. For example: { "dnsRuleId": "dnsRule1", "domainName": "www.example.com", "ipAddressType": "IP_V4", "ipAddress": "192.0.2.0", "ttl": "?", "state": "ACTIVE" }
