URGENT, PLEASE HELP

[#1]

Hi Team,

I have an urgent question.

I have a question wrt API.

If I ask for next available IP from a subnet using Infoblox API and don’t create any host record against it.

Now after 5 sec , I shoot another API asking for next available IP , will I get the same IP???

My question is will the Infoblox save the IP temporarily for some time or not ?? If yes, what’s the time??

Calling next_available_ip on a network does not reserve it for any future use.  If you run next_available_ip on the same network multiuple times, you will get the same address back every time.

$ curl -k1 -u admin:infoblox -X POST 'https://192.168.1.6/wapi/v2.9/network/ZG5zLm5ldHdvcmskMTAuOS4xNi4wLzI0LzA:192.168.1.0/2/default?_function=next_available_ip'
{
    "ips": [
        "192.168.1.25"
    ]
}
$ curl -k1 -u admin:infoblox -X POST 'https://192.168.1.6/wapi/v2.9/network/ZG5zLm5ldHdvcmskMTAuOS4xNi4wLzI0LzA:192.168.1.0/2/default?_function=next_available_ip'
{
    "ips": [
        "192.168.1.25"
    ]
}
$ curl -k1 -u admin:infoblox -X POST 'https://192.168.1.6/wapi/v2.9/network/ZG5zLm5ldHdvcmskMTAuOS4xNi4wLzI0LzA:192.168.1.0/2/default?_function=next_available_ip'
{
    "ips": [
        "192.168.1.25"
    ]
}
$

To reserve it immediately against future use, you would need to create an object on that ip address, or create an object using the next_available_ip function.

Here's a host record example, which excludes the .1 address in the requested network:

curl -k1 -u admin:infoblox -H 'Content-Type: application/json' -X POST \ 'https://192.168.1.6/wapi/v2.9/record:host' -d '{"name": "test.example.org", "ipv4addrs": [{"ipv4addr": {"_object_function": "next_available_ip", "_object": "network", "_object_parameters": {"network": "192.168.1.0/24"}, "_result_field": "ips", "_parameters": {"num": 1, "exclude": ["192.168.1.1"]}}}]}'

Thanks for your answer. 

Can I use API asking for next available IP and in the same request pass on few IP's which Infoblox should ignore while giving me next available IP ??

Yes, anything in square brackets is an array.  That section would look like this:

"exclude": ["192.168.1.1","192.168.1.2","192.168.1.3"]

 You could also place an exclusion range or a set of reservations in the network, to block out addresses.
