How is it possible to have a box with an inet of 192.186.56.101 and another on 10.0.2.15?

On virtualbox I have a machine running metasploitable2 with an inet of 192.168.56.101 and I also have a kali machine with an inet of 10.0.2.15 on the same network, how is this possible?

Does having the metasploitable2 machine on a “host-only adapter” have something to do with this?
