Incident Response Basics Trying to Do Lab

I am following instructions & it is not allowing me to do lab. If a lab requires fumbling around that should be included in instructions.

The IP address looks to be incorrect. It will start with 10. not 101. The lab IP seem to start with 10.91 or 10.101 so if I had to guess I would say the IP should be 10.101.12.145.
