How can I find out how many IP addresses have been used in a subnet?

I have a /23 subnet in my VPC. I want to find out how many IP addresses have been used in that subnet.

Hi @rndnds,

Welcome to Google Cloud Community!

I would recommend our Network Analyzer specifically VPC network insights for your use case. It is capable of showing both IP address utilization and Unused IP address through:

• IP address utilization insights
• Unused IP address insights

Here’s a sample below of my VPC subnetwork allocation ratio:

I hope the information above is helpful.
