IPAM REST API questions

To expand on your questions a bit
There's a rest API, if you use it you'll end up using SWQL sooner or later for querying something. There are API calls with no SWQL though.

1/2 on sufficiency, on a technical level you need time and such as in my SS, or on  non-technical level depends on your org i suppose.

I think release is Cancel or Remove.

THANK YOU
It's extremely useful and what I was looking for.
I guess I need to play around those settings as soon as I get access to the systems.

First of all I need to find how the IPs are "reserved". Are they reserved as DHCP records, or it's just a "available" "not available" status? 
Then, I need the correct option (unfortunately I cannot find what I have to type there, but I believe that's for another day).

But many thanks, it's a very good starting point

Someone IPAM-ey will have to jump to help from there I think, I'm more familiar with the api stuff
