AzNetworkTool CLI extends Azure CLI for network operationnal needs.
This CLI helps us daily to:
- Find to which of our Azure resource(s) belong an IP Address, whether public or private. NIC, (I|E)LB, Redis & Public IPs supported.
- Find available subnets in a virtual network.
- Find an address space when we to create a virtual Network that not overlap with existing virtual networks. Useful when we need to peer Virtual Networks.
