IPAM update between two GRIDs

[#1]

Hello,

We currently have an On-premise infrastructure and a Cloud infrastructure and each has the IPAM service
We wish to have an update of all the networks (IPAM) created in the Cloud infrastructure.
       1-How can we have an update on the DDI On-premise infrastructure of all the networks created in the Cloud IPAM?
      2-How to blog an IP address as a network gateway (IPAM) so that it is not used for other needs

Best regards

Look into cloud network automation / infoblox cloud platform. This will allow you to make API calls to reserve networks and update information via cloud infra to a cloud member.
