Funny enough, we had an integration with Infoblox at some point: https://www.checkpoint.com/downloads/partners/checkpoint-infoblox-solution-brief.pdf
However, this appears to be Threat Prevention focused.
If I'm understanding what @dj0Nz is doing in the script, the data is being read from Infoblox and is being written to our Management API with some minimal error checking.
That seems like the most reasonable approach here and is certainly possible with APIs and appropriate scripting.
If you want to keep this data in sync, that's also feasible, but further development is clearly required.
If there are other specific use cases, they may or may not be possible depending on available APIs.
