import ipaddress


ADDRESSES = [
    '172.16.254.00'
]

for ip in ADDRESSES:
    addr = ipaddress.ip_address(ip)
    if addr.version==4:
        {
            print("true")
        }
    else:
        {
            print("false")
        }

I tried to validate an invalid IPv4 address using IPaddress library from py 3.8.6 but somehow it considers any address ending with "00" to be valid.

I hope this is helpful to the community please let me know if the issue is with validation from your end or a bug in the library.
