ipaddress doesn't properly tag reserved IP in 192.0.0.0/24?

Question

I'm trying to setup a script using ipaddress module in python 3.x. I'm looking for making a parser looking for some info on public IP.

When checking the IP, I'm finding that ipaddress is not tagging as reserved the IP range 192.0.0.0/24.

From IETF docs :

192.0.0.0/24 192.0.0.0–192.0.0.255 Private network IETF Protocol Assignments.

From ipaddress docs :

is_reserved: True if the address is otherwise IETF reserved.

The code :

import ipaddress
print(ipaddress.ip_address("192.0.0.12").is_reserved)

Output :

False

Is there something I'm doing wrong ?
