Why is NMAP showing more hosts than expected?

I am using VMware Workstation, and I have a few VMs installed. When I turn on Kali VM (192.168.140.13) and Windows 10 VM (192.168.140.15) and run NMAP on Kali. I received the following output:

└─# nmap 192.168.145.0/24Nmap scan report for 192.168.140.1Nmap scan report for 192.168.140.2Nmap scan report for 192.168.140.15Nmap scan report for 192.168.140.254Nmap scan report for 192.168.140.13Nmap done: 256 IP addresses (5 hosts up) scanned in 10.72 seconds

The question is why is it showing 5 hosts up? I know the default gateway is 192.168.140.2. But, what about 192.168.140.1 and 192.168.140.254?

thank you!
