what is this and why? I work in private VPCs in AWS a lot. I’m testing, debugging, and fidgeting with instances, requiring SSH access. If DNS isn’t configured, I’ve then had to look up IP addresses for instances through the AWS console (or just memorize the IP). After that, there’s the SSH public host key fingerprint. I either blindly accept it or manually look it up. If I terminate and redeploy the instance, there’s a chance I’ll get that SSH WARNING!
