How to create host record and assign the hostname to an unused IP

[#1]

Hi infoblox family,

I was looking through the documentation of infoblox and I got the API calls to search the record hosts with zone name  (testingwapi-hostname is already created by me in UI)

API call:

https://["URL"]/wapi/v2.10.3/allrecords?zone="domain_name"&name=testingwapi

I am looking to use POST API call method to create a record host with a hostname and zone and use the record host _ref to create another POST API call to assign an IPv4 address.

It is not possible unfortunately.  The IP address must be added as part of the initial creation, either by supplying it directly or by using a next_available_ip function.
