I can’t speak to AWS but I do it in Azure. In Azure an IP address isn’t ever released/reassigned until you “Force Stop” a VM which causes the IP, memory and vProcs to be deallocated from the VM.
(Azure also has other options – this is just the default.)

Someone from another one of our IT groups has provisioned some servers at AWS for Citrix and the proposal is to add a couple of DCs there. He says “All AWS instance should always be DHCP clients”. I think of this as a bad practice, but I would think that if it’s the standard at AWS, then lots of others are doing the same. So even better would be if I could hear from someone who does have DCs at AWS. I have cloned DCs in an isolated test network, which we regularly use for testing. I’ll be connecting those to the DCs I’m building at AWS for testing before even attempting this in production. Even if I have no problems in testing, I am leery to do this in prod.
