vagrantfileを編集してIPアドレスを動画の通りに直しから
vagrant upをして
vagrant statusをしたのですが

Current machine states:

default not created (virtualbox)

The environment has not yet been created. Run `vagrant up` to
create the environment. If a machine is not created, only the
default provider will be shown. So if a provider is not listed,
then the machine is not created for that environment.
と結果が返ってきます。
