- moduspol 7y agoI could have missed it, but I've never seen a suggestion not to overlap network addresses unless you want to peer them. If you're launching ephemeral networks for testing VMs / virtual appliances in their own, isolated networks, it can be totally feasible to have lots of them using the same addresses. You can only create 5 VPCs (at all) by default per AWS account, but they'll raise that limit for you if you request it.
