Retrieve lost internal ip addressess

[sakibapur]

Hey guys can you help me, I want to search released internal IP address in all my project from my VPC.

Hi,

I replicate this concern by creating a custom vpc network, reserving a static internal IP address and assigning to a certain VM instance then delete the instance and release the static address. 

I tried to check this information in activity logs and also under logging under GCE Address resource, unfortunately there is no information wherein you can see the exact IP address that is already deleted.
