Hello @Lior Elayev ,
I understand that you would like to know if there is a way to get the resolved IP of FQDN objects that are configured on network/application rules collection on firewall policies.
I checked with the Azure Firewall Product Group team, and they confirmed that as of today, there is no native API or feature which could get the resolved IP of FQDN configured on network/application rules.
I would request you to leave your feedback in the below forum requesting this feature. All the feedback you share in these forums will be monitored and reviewed by the Microsoft engineering teams responsible for building Azure.
