SSH without user-known hosts checking

If the IP address of the host you are connecting to frequently changes, as in the case of cloud instances, but you are sure that that you are connecting to the correct host, you can use the following ssh command to disable known host checking (Note: This may lead to MITM attacks).

ssh -o UserKnownHostsFile=/dev/null user@10.0.3.x
