When I used

nmap -sP IP/24 -v,

nmap scanned for around 5 minutes. Then it reported that all 256 hosts are up.

But when I used

nmap -sP * .* .*.253 -v

it said the host wasn't up.

What's going on here?

You can use nmap -sO -v IP/24. -sO means IP protocol scan. You can also see which machines are open in this scan.
